94-461: The Loddiges family (not uncommonly mis-spelt Loddige ) managed one of the most notable of the eighteenth and nineteenth century plant nurseries that traded in and introduced exotic plants, trees, shrubs, ferns, palms and orchids into European gardens. The founder of the nursery was Joachim Conrad Loddiges (1738–1826). He was born in Hildesheim , Lower Saxony ; his father Casper Lochlies
188-410: A Christie's auction for $ 9.65 million). On the death of George Loddiges in 1846, the nursery business passed to his son Conrad Loddiges II (1821–1865), who found it increasingly difficult to negotiate a new lease from the land-owner (St. Thomas' Hospital), given the much higher prices the land could now command for housing development, due to London's growth into the surrounding countryside. Similarly,

In outplanted trees, maximum stomatal conductances (g) were initially low (<0.01 cm/s), and initial base xylem pressure potentials (PSIb) were -2.0 MPa. During the growing season, g increased to about 0.20 cm/s and PSIb to -1.0 MPa. Minimum xylem pressure potential (PSIm) was initially -2.5 MPa, increasing to -2.0 MPa on day 40, and about -1.6 MPa by day 110. During

Stock for fall planting must be properly hardened-off. Conifer seedlings are considered to be hardened off when the terminal buds have formed and the stem and root tissues have ceased growth. Other characteristics that in some species indicate dormancy are color and stiffness of

Today, memorials to members of the Loddiges family can be seen in the gardens of the Church of St John-at-Hackney and Abney Park Cemetery . Standard botanical author abbreviations for the Loddiges family: Plant nurseries A nursery
658-462: A greater early season resistance to water-flow through the soil–plant–atmosphere continuum (SPAC) than had containerized outplants. Resistance to water flow through the SPAC decreased in bareroot stock of both species as the season progressed, and was comparable to containerized seedlings 9 to 14 weeks after planting. Bareroot black spruce had greater new-root development than containerized stock throughout
752-695: A high-elevation planting study in southeastern British Columbia. In the larger gaps (≥1.0 ha), height increment by year 6 was ranging from 10 cm to 20 cm. Lajzerrowicz et al. Concluded that plantings of conifers in clearcuts at high elevations in the southern mountains of British Columbia are likely to be successful, even close to timberline; and group selection silvicultural systems based on gaps 0.1 ha or larger are also likely to succeed. Gaps smaller than 0.1 ha do not provide suitable conditions for obtaining adequate survival or for growth of outplanted conifers. Planting stock, "seedlings, transplants, cuttings, and occasionally wildings, for use in planting out,"
846-487: A major influence on field performance. The field performance among various stock types in Ontario plantations was examined by Paterson and Hutchison (1989): the white spruce stock types were 2+0, 1.5+0.5, 1.5+1.5, and 3+0. The nursery stock was grown at Midhurst Forest Tree Nursery, and carefully handled through lifting on 3 lift dates, packing, and hot-planting into cultivated weed-free loam. After 7 years, overall survival
940-511: A minimized handling and lifting-planting cycle, a system based on specification for nursery stock and minimum morphological standards for acceptable seedlings works tolerably well. In certain circumstances, benefits often accrue from the use of large planting stock of highly ranked morphological grades. Length of leading shoot, diameter of stem, volume of root system, shoot:root ratios, and height:diameter ratios have been correlated with performance under specific site and planting conditions. However,

Close to the Abney Park Chapel he also laid out a rosarium to complement the chapel's 'botanical rose windows' (described as 'botanical' owing to their unusual ten-part arrangement, as in the five sepals and five petals of the rose family , or petals of a simple rose including indentations as shown in the White Rose of York ). George Loddiges also appears to have influenced

Heat shock increased soluble HSP 72/73 levels in both the morning and afternoon. In all instances, shoot and root heat tolerances were significantly greater in the afternoon than in the morning. Planting stock continues to respire during storage even if frozen. Temperature is the major factor controlling
1222-450: A percentage of TA was higher in field-planted white spruce than jack pine until the end of the season. The stomata of both white and black spruce were more sensitive to atmospheric evaporative demands and plant moisture stress during the first growing season after outplanting on 2 boreal sites in northern Ontario than were jack pine stomata, physiological differences that favoured growth and establishment being more in jack pine than in
1316-407: A root system to develop new roots or extend existing roots cannot be determined by eye, yet it is the factor that makes or breaks the outcome of an outplanting operation. The post-planting development of roots or root systems of coniferous planting stock is determined by many factors, some physiological, some environmental. Unsatisfactory rates of post-planting survival unrelated to the morphology of

Propagation nurseries may also sell plant material large enough for retail sales and thus sale directly to retail nurseries or garden centers (which rarely propagated their own plants). Nurseries may produce plants for reforestation , zoos, parks, and cities. Tree nurseries in

The survival and growth of Engelmann spruce and subalpine fir outplanted in 3 silvicultural trials on such sites in gaps of various sizes were compared by Lajzerowicz et al. (2006). Survival after 5 or 6 years decreased with smaller gaps. Height and diameter also decreased with decreasing size of gap; mean heights were 50 cm to 78 cm after 6 years, in line with height expectations for Engelmann spruce in
1598-507: A small seed and gardening business in the village of Hackney, north of London, with assistance from a fellow German emigree, Johann (syn. John) Busch. Busch was appointed as chief gardener to Catherine the Great and the two remained in contact - it is through this connection that the Loddiges had a role in importing and establishing rhubarb in Britain. Seed packets were received from all over
1692-404: A small seed business started by fellow German émigré John Busch, which he purchased, together with the good will of Busch's clientele in 1771 and had fully paid for by 1777, by which time he began to write to people all over the world, urging them to send him packets of seeds collected from trips to native hills, valleys and plains. From these small beginnings, its initial catalogue appearing in 1777
1786-414: A specific number and size of plant, while others produce a wide range of plants that are offered for sale to other nurseries and landscapers and sold as first come first served. Retail nurseries sell plants ready to be placed in the landscape or used in homes and businesses. Propagation nurseries produce new plants from seeds, cuttings, tissue culture, grafting, or division. The plants are then grown out to

If the landscape of the nursery has sections of land where erosion could occur, the nursery needs to come up with a solution such as by using erosion prevention structures like rip rap. Topography impacts nursery design and layout and it

A few years later, in 1829, Jacob Rinz (a visitor from a Frankfurt nursery) commented: never shall I forget the sensation produced by this establishment. I cannot describe the raptures I experienced on seeing that immense palm house. All that I had seen before of the kind appeared nothing to me compared with this. I fancied myself in the Brazils; and especially at that moment when Mr Loddiges had

Soil Conditions For a nursery to produce healthy crops, it will need to have healthy soil. The soil should have good drainage and nutrient holding capacity. Soil testing will help a nursery find out its pH levels, and also
2350-576: Is a person who owns or works in a nursery. Some nurseries specialize in certain areas, which may include: propagation and the selling of small or bare root plants to other nurseries; growing out plant materials to a saleable size, or retail sales. Nurseries may also specialize in one type of plant, e.g., groundcovers , shade plants, or rock garden plants. Some produce bulk stock, whether seedlings or grafted trees, of particular varieties for purposes such as fruit trees for orchards or timber trees for forestry. Some producers produce stock seasonally, ready in

They include retail nurseries, which sell to the general public; wholesale nurseries, which sell only to businesses such as other nurseries and commercial gardeners ; and private nurseries, which supply the needs of institutions or private estates. Some will also work in plant breeding . A " nurseryman "

The nursery manager aims, and is normally able to avoid stresses greater than moderate, i.e., restricting stresses to levels that can be tolerated by the plants without incurring serious damage. The adoption of nursery regimes to equip planting stock with characteristics conferring increased ability to withstand outplanting stresses, by managing stress levels in

Types of stock include bareroot seedlings and transplants, and various kinds of containerized stock. For simplicity, both container-grown and bareroot stock are generally referred to as seedlings, and transplants are nursery stock that have been lifted and transplanted into another nursery bed, usually at wider spacing. The size and physiological character of stock vary with

The potential for survival and growth of a batch of planting stock may be estimated from various features, morphological and physiological, of the stock or a sample thereof. The size and shape and general appearance of a seedling can nevertheless give useful indications of PSPP. In low-stress outplanting situations, and with

He was the son of Joachim Conrad Loddiges (c.1738–1826) and Sarah Aldous. Joachim Loddiges was a German-born nurseryman who founded Conrad Loddiges and Sons, one of the largest nurseries in the 1800s. Along with his brother William, George also trained in the trade of plants and
2914-485: Is nursery stock that has been made ready for outplanting. The amount of seed used in white spruce seedling production and direct seeding varies with method. A working definition of planting stock quality was accepted at the 1979 IUFRO Workshop on Techniques for Evaluating Planting Stock Quality in New Zealand: "The quality of planting stock is the degree to which that stock realizes the objectives of management (to

3008-955: Is planted, undergoes any substantive physiological or physical change. In its present form, RGC testing is silviculturally useful chiefly as a means of detecting planting stock that, while visually unimpaired, is moribund. Seedling moisture content can be increased or decreased in storage, depending on various factors including especially the type of container and the kind and amount of moisture-retaining material present. When seedlings exceed 20 bars PMS in storage, survival after outplanting becomes problematical. The Relative Moisture Content of stock lifted during dry conditions can be increased gradually when stored in appropriate conditions. White spruce (3+0) packed in Kraft bags in northern Ontario increased RMC by 20% to 36% within 40 days. Bareroot 1.5+1.5 white spruce were taken from cold storage and planted early in May on
3102-790: Is reflected by changes in root activity. This is helpful in determining the readiness of stock for lifting and storing and also for outplanting after storage. Navratil (1982) reported a virtually perfect (R² = 0.99) linear relationship in the frequency of 3+0 white spruce white root tips longer than 10 mm with time in the fall at Pine Ridge Forest Nursery, Alberta, decreasing during a 3-week period to zero on October 13 in 1982.Root regenerating research with white spruce in Canada (Hambly 1973, Day and MacGillivray 1975, Day and Breunig 1997) followed similar lines to that of Stone's (1955) pioneering work in California. Simpson and Ritchie (1997) debated

For example, the term ' arboretum ' was first used in an English publication by J. C. Loudon in 1833 in The Gardener's Magazine when commenting on George Loddiges' famous Hackney Botanic Garden arboretum, begun in 1816, and open free to
3290-458: The U.S. produce around 1.3 billion seedlings per year for reforestation projects. Nurseries grow plants in open fields, on container fields, in tunnels or greenhouses. In open fields, nurseries grow decorative trees, shrubs and herbaceous perennials. On a containerfield nurseries grow small trees, shrubs and herbaceous plants, usually destined for sales in garden centers. These have proper ventilation, sunlight etc. Plants may be grown by seeds, but
3384-484: The abundance of HSPs depending on protein fraction and time of day. Without heat shock, nuclear membrane-bound HSP 73 was absent from plants in the morning and only weakly present in the afternoon, and heat shock increased the abundance of nuclear membrane. Heat shock also affected the abundance of HSP 73 in the afternoon, and caused HSP 73 to appear in the morning. In the mitochondrial and microsomal protein fractions, an afternoon heat shock reduced HSP 73 , whereas

In the Lake States, Kittredge concluded that good stock of 2+1 white spruce was the smallest size likely to succeed and was better than larger and more expensive stock when judged by final cost of surviving trees. Because age alone is an inadequate descriptor of planting stock, various codes have been developed to describe such components of stock characteristics as height, stem diameter, and shoot:root ratio. A description code may include an indication of

Schmidt-Vogt (1980), for instance, found that whereas mortality among large outplants is greater than among small in the year of planting, mortality in subsequent growing seasons is higher among small outplants than among large. Much of the literature on comparative seedling performance is clouded by uncertainty as to whether

The young plants were supplied to the Marquis of Rockingham whose interest led to great enthusiasm for growing the species in British gardens. Conrad's son George Loddiges is generally credited with raising the profile of the exotic Hackney nursery at least as greatly, if not more so, than his eminent horticulturalist father. In 1833

There is quite a forest of them: his hot-houses are, perhaps, the most capricious in the world: one off them is forty feet high: in this there
4606-657: The forest policy of the organization. A distinction needs to be made between "planting stock quality" and "planting stock performance potential" (PSPP). The actual performance of any given batch of outplanted planting stock is determined only in part by the kind and condition, i.e., the intrinsic PSPP, of the planting stock. The PSPP is impossible to estimate reliably by eye because outward appearance, especially of stock withdrawn from refrigerated storage, can deceive even experienced foresters, who would be offended if their ability were questioned to recognize good planting stock when they saw it. Prior to Wakeley's (1954) demonstration of

The greater efficiency of water use in newly transplanted 3-year-old white spruce seedlings under low levels of absolute humidity difference in water-stressed plants immediately after planting helps explain the commonly observed favourable response of young outplants to the nursing effect of a partial canopy. Silvicultural treatments promoting higher humidity levels at the planting microsite should improve white spruce seedling photosynthesis immediately after planting. Planting stock

Gradually, however, a realization developed that more was involved. Tucker et al. (1968), for instance, after assessing 10-year survival data from several experimental white spruce plantations in Manitoba noted that "Perhaps
4982-516: The intended planting season. George Loddiges George Loddiges (1784/1786 – 5 May 1846) was a British gardener, artist, and naturalist. He worked in the nursery business established by his father and illustrated nearly 2000 plates of plants in the nursery's own periodical, the Botanical Cabinet , published between 1817 and 1833. He also planned a book on the hummingbirds but this was not published. The hummingbird genus Loddigesia

Until the technology of raising containerized nursery stock bourgeoned in the second half of the twentieth- century, bareroot planting stock classified by its age in years was the norm. The number of years spent in the nursery seedbed by any particular lot of planting stock is indicated by the 1st of a series of numbers. The 2nd number indicates

Dobbs (1976) and McMinn (1985a) examined how the performance of 2+0 bareroot white spruce related to differences in initial size of planting stock. The stock was regraded into large, medium, and small fractions according to fresh weight. The small fraction (20% of

George Loddiges was involved in establishing the Abney Park cemetery garden in 1839-40. The Loddiges worked with plant collectors from around the world as well as botanists. Hugh Cuming was one of their collectors and Nathaniel Ward

The term LT 50 (lethal temperature for 50% of a population) is commonly used. Determination of frost hardiness in Ontario is based on electrolyte leakage from mainstem terminal tips 2 cm to 3 cm long in weekly samplings (Colombo and Hickie 1987). The tips are frozen then thawed, immersed in distilled water,

Seedlings exhibited constitutive synthesis of HSP 73 at 26 °C in all except the nuclear membrane fraction in the morning; HSP levels at 26 °C in the afternoon were higher than in the morning in the mitochondrial and microsomal protein factions. Heat shock affected
5640-560: The most common method is by planting cuttings, which can be taken from shoot tips or roots. With the objective of fitting planting stock more able to withstand stresses after outplanting, various nursery treatments have been attempted or developed and applied to nursery stock. Buse and Day (1989), for instance, studied the effect of conditioning of white spruce and black spruce transplants on their morphology, physiology, and subsequent performance after outplanting. Root pruning, wrenching, and fertilization with potassium at 375 kg/ha were

5922-475: The nursery business gained a specialist market in Britain, and was increasingly able to attract clients from estates and botanical gardens throughout Europe. The nursery rose to great prominence during the early nineteenth century under George Loddiges (1786–1846). From 1818 to 1833 Conrad and Sons published 20 issues of The Botanical Cabinet [ es ] , a magazine consisting of over 1000 coloured plates of rare plants that were introduced from around

Outplanted stock that is unable to tolerate high temperatures occurring at soil surfaces will fail to establish on many forest sites, even in the far north. Factors affecting heat tolerance were investigated by Colombo et al. (1995);

Although the business closed in the 1850s, it leaves an important legacy in many of our gardens and parks, since a number of the attractive plants we take for granted, were first introduced into cultivation by Loddiges Nursery. On 2 January 1770, following his marriage, Joachim Conrad Loddiges wrote to his longstanding employer, Dr Silvester, asking for advice about his plan to move on from head gardener and grounds keeper, and set up

Ten years later, in the blade-scarified site, seedlings of the large fraction had almost 50% greater stem volume than had seedlings of the small fraction. Without site preparation, large stock were more than twice the size of small stock after 10 years. Similar results were obtained with regraded 2+1 transplants sampled to determine root growth capacity. The large stock had higher RGC as well as greater mass than

Conrad was involved with the display of ferns and terrariums for the Great Exhibition . The nursery closed in stages between 1852 and 1854 due to expiry of the lease from St. Thomas' Hospital. Conrad Loddiges II offered the whole of

HSPs, present constitutively in black spruce and many other, perhaps most, higher plants are important both for normal cell functioning and in a stress response mechanism following exposure to high, non-lethal temperature. In black spruce at least, there is an association between HSPs and increased levels of heat tolerance. Investigation of

Navratil (1982) found that closed containers in cold storage averaged internal temperatures 1.5 °C to 2.0 °C above the nominal storage temperature. Depletion of reserves can be estimated from the decrease in dry weight. Cold-stored 3+0 white spruce nursery stock in northern Ontario had lost 9% to 16% of dry weight after 40 days of storage. Carbohydrates can also be determined directly. The propensity of

As well, an excess of nutrient ions can prolong or weaken growth to interfere with the necessary development of dormancy and hardening of tissues in time to withstand winter weather. Nursery stock size typically follows the normal curve when lifted for planting stock. The runts at

An example is in Ontario, irrigation water is used most in late spring and in summer, when plants need water most, and based on climate patterns in Ontario, this time is also when there is the least amount of rainfall. Some nurseries will create water sources by building
6956-485: The small stock fraction. The value of large size at the time of planting is especially apparent when outplants face strong competition from other vegetation, although high initial mass does not guarantee success. That the growth potential of planting stock depends on much more than size seems clear from the indifferent success of the transplanting of small 2+0 seedlings for use as 2+1 "reclaim" transplants. The size of bareroot white spruce seedlings and transplants also had
7050-496: The soil to develop any appreciable storehouse of available nitrogen for future crops. Phosphorus and potassium, however, can be accumulated as a storehouse available for extended periods. Fertilization permits seedling growth to continue longer through the growing season than unfertilized stock; fertilized white spruce attained twice the height of unfertilized. High fertility in the rooting medium favours shoot growth over root growth, and can produce top-heavy seedlings ill-suited to
7144-444: The sole predictor of plantation performance. Some major problems militate against greater use of RGC in forestry, including: unstandardized techniques; unstandardized quantification; uncertain correlation between quantified RGC and field performance; variability within given, nominally identical, kinds of planting stock; and the irrelevance of RGC test values determined on a sub-sample of a parent population that subsequently, before it
7238-487: The spring for export to colder regions where propagation could not have been started so early or to regions where seasonal pests prevent profitable growing early in the season. There are a number of different types of nurseries, broadly grouped as wholesale or retail nurseries, with some overlap depending on the specific operation. Wholesale nurseries produce plants in large quantities which are sold to retail nurseries Wholesale nurseries may be small operations that produce
7332-574: The spruces. With black spruce and jack pine, but not with white spruce, Grossnickle and Blake's (1987) findings warrant mention in relation to the bareroot-containerized debate. During the first growing season after outplanting, containerized seedlings of both species had greater needle conductance than bareroot seedlings over a range of absolute humidity deficits. Needle conductance of containerized seedlings of both species remained high during periods of high absolute humidity deficits and increasing plant moisture stress. Bareroot outplants of both species had
7426-435: The stock, led to attempts to test the physiological condition of planting stock, particularly to quantify the propensity to produce new root growth. New root growth can be assumed to be necessary for successful establishment of stock after planting, but although the thesis that RGC is positively related to field performance would seem to be reasonable, supporting evidence has been meager. The physiological condition of seedlings
7520-475: The stocks being compared share the same physiological condition; differences invalidate such comparisons. Height and root-collar diameter are generally accepted as the most useful morphological criteria and are often the only ones used in specifying standards. Quantification of root system morphology is difficult but can be done, e.g. by using the photometric rhizometer to determine intercept area, or volume by displacement or gravimetric methods. Planting stock
7614-556: The textual supplement to his epic "Birds of America" series of 435 plates (1826-1838). Writing about the "Anna Humming Bird" in the Ornithological Biography, Audubon wrote, "...Those [figures/paintings] of the male I made from specimens, for the use of which I am indebted to Mr. Loddiges, of London, whose collection of Humming Birds is unrivaled." (In June 2018 an original, 4-volume edition of the Birds of America sold at
7708-436: The treatments applied. Root pruning and wrenching modified stock in the nursery by decreasing height, root collar diameter, shoot:root ratio, and bud size, but did not improve survival or growth after planting. Fertilization reduced root growth in black spruce but not of white spruce. For a nursery to produce healthy crops, they must manage many factors, a few of them being irrigation, landscape topography, and soil conditions of
7802-942: The world into the nursery's gardens and hothouses. The largest hothouses in the world were built to display the best collection of palms and orchids in Europe. George Loddiges also linked the nursery into the scientific circles of the day, becoming a Fellow of the Microscopical Society (FMS), Fellow of the Linnean Society (FLS), Fellow of the Horticultural Society (FHS), and Fellow of the Zoological Society (FZS) in London, for he had wide interests in scientific subjects beyond botany, becoming particularly knowledgeable about early microscopy and one aspect of ornithology (humming-birds). Abroad
7896-584: The world, sometimes from well-known botanical explorers such as John Bartram and William Bartram in North America (who also favoured Quaker horticulturalists such as Peter Collinson with discoveries), and sometimes from ordinary travelers. One of the first plant species to be introduced into cultivation in Britain by Conrad Loddiges was the Common Mauve Rhododendron , Rhododendron ponticum . He introduced this into England in
7990-406: The years subsequently spent in the transplant line, and a zero is shown if indeed there has been no transplanting. A 3rd number, if any, would indicate the years subsequently spent after a second lifting and transplanting. The numbers are sometimes separated by dashes, but separation by plus sign is more logical inasmuch as the sum of the individual numbers gives the age of the planting stock. Thus 2+0
8084-445: The young Edward Cooke who became a leading Victorian artist, and whose father, George Cooke , engraved a number of the plates. The Horticultural Society awarded George Loddiges numerous medals throughout this period: Silver Medal, 1818, 1819; Silver Medal (Sir Joseph Banks Memorial Portrait Prize), 1823, 1826, 1832, 1835; President's Silver Medal, 1836; Silver Flora Medal, 1837. In the late 1830s, George Loddiges became involved in
8178-430: Was 80-87%. Available turgor (TA), defined as the integral of turgor over the range of RWC between PSIb and xylem pressure potential at the turgor loss point) was 4.0% for white spruce at the beginning of the season compared with 7.9% for jack pine, but for the rest of the season TA for jack pine was only 2%, to 3% that of white spruce. Diurnal turgor (Td), the integral of turgor over the range of RWC between PSIb and PSIm, as
8272-586: Was 97%, with no significant differences in survival among stock types. The 1.5+1.5 stock with a mean height of 234 cm was significantly taller by 18% to 25% than the other stock types. The 1.5+1.5 stock also had significantly greater dbh than the other stock types by 30-43%. The best stock type was 57 cm taller and 1 cm greater in dbh than the poorest. Lifting date had no significant effect on growth or survival. High elevation sites in British Columbia's southern mountains are characterized by
8366-522: Was a friend. Several species of plant have been named after members of the Loddiges family. Loddiges was a member of the councils of the Linnean Society , the Horticultural Society , and the Microscopical Society . He had a collection of 200 species of hummingbirds which were acquired by the British Museum of Natural History in 1933. He had planned to publish a book on the hummingbirds. He married Jane Creighton (1787–1859) in 1811 and they had
8460-603: Was a gardener to a nobleman in Wrisbergholzen, near Hannover . Conrad trained in The Netherlands and emigrated to Britain at the age of 19 during the Seven Years' War to take up employment as gardener for Dr J. B. Silvester in the suburban village of Hackney , north of London. It was then that the family name was anglicised. When in his forties he married, he had not accumulated sufficient savings to expand
8554-540: Was included in The Encyclopaedia of Gardening 1834 edition, and the interest this aroused helped inspire Loudon to write his encyclopaedic book Arboretum et Fruticetum Britannicum , first published in 1838. Although this incorporated drawings from several early botanic gardens and parklands throughout the UK, it relied greatly upon, and would not have been possible without, George Loddiges' well labeled arboretum. It
8648-613: Was on the collection maintained by this firm more than any other that J.C.Loudon relied for living material in the preparation of his great work W.J.Bean notes in Trees and Shrubs Hardy in the British Isles , today's standard reference work. Another notable visitor was Charles Darwin who in September 1838 wrote Saw in Loddiges garden 1279 varieties of roses!!! Proof of capability of variation Although George Loddiges' arboretum
8742-441: Was prompted to begin marketing a series of volumes containing coloured engravings of the many new species and varieties. Entitled The Botanical Cabinet it ran to twenty volumes and 2,000 plates. Facing each plant portrait, George Loddiges added a few lines of text outlining the source of the seeds and invariably adding a religious perspective. Many of the drawings for the publications were made by George himself, his daughter Jane and
8836-598: Was widely praised, his better known horticultural endeavour was to establish the world's largest hothouse in his Hackney Botanic Nursery, and invent a system of warm mist-like rain to maintain beautiful tropical palms, epiphytic orchids, ferns and camellias in almost perfect environmental conditions akin to a 'tropical rainforest'. George Loddiges' tropical hothouse range made use of recently invented curvilinear iron glazing bars and central heating systems, which together with his own inventions, enabled many new species of tropical plant to be introduced into cultivation, or flower for
