By the time John Claudius Loudon (1783-1843) Scottish botanist, garden designer & author, published his 1824 An encyclopaedia of gardening: comprising the theory & practice of horticulture, floriculture, arboriculture, & landscape-gardening, including all the latest improvements; a general history of gardening in all countries; & a statistical view of its present state... many definitions of those involved in gardening had become fairly universally accepted on both sides of the English-speaking Atlantic.
In this essay, I will attempt to use Louden's descriptions of garden positions as closely as possible. Where the definition in America differed from the English usage, I have altered the description to reflect American usage.
Garden Laborer. Garden laborers are the lowest grade in the scale of working gardeners. In 18C America, they are usually a convict or indentured servant or slave, male & female. They are occasionally employed to perform the common labors of gardening, as trenching, digging, hoeing, weeding, &c. Men for the more heavy, & women for the lighter employments. Most garden-laborers have not received any professional instruction, farther than what they may have obtained by voluntary or casual observation. In all gardens where 3 or 4 professional hands are constantly employed, some laborers are required at extraordinary seasons & tasks. In the larger gardens of the 19th century American south, most garden laborers are enslaved African Americans.
Apprentice Gardener. Youths intended for serving to learn the trade of gardener, are placed under master or tradesmen gardeners, for a given period, on terms for mutual benefit: the master contracting to supply instruction, & generally food & lodging, or a weekly sum as an equivalent; & the parents of the apprentice gardener granting the services of the latter during his apprenticeship as their part of the contract. The terms agreed on is generally 3 years; or more if the youth is under 16 years of age but whatever may be the period, by the laws as to apprentices it must not extend beyond that at which the youth attains the age of manhood. Few can expect to attain to the rank either of master-gardener or tradesman, who has not served an apprenticeship to the one or the other. In general, it is preferable to apprentice youths to master-gardeners, as their the labor is less than in tradesmen's gardens, & the opportunities of instruction is generally much greater.
Journeyman Gardener. The period of apprenticeship being finished, that of jouneyman commences, & ought to continue till the man is at least 25 years of age. During this period, they ought not to remain above 1 year in any one situation; thus, supposing they have completed apprenticeship in a private garden at the age of 21, & that the ultimate objective is to become a head-gardener, they ought first to engage themselves a year in a public botanic garden; the next year in a public nursery; that following, they should again enter a private garden, & continue making yearly changes in the most eminent of this class of gardens, till they meet with a situation as head gardener. The course to be followed by an apprentice intended for a tradesman-gardener is obvious; having finished his period in a private garden, let him pass through a botanic & nursery garden, & then continue in the most eminent of the class of public or tradesmen's gardens, to which they are destined.
Garden Foreman. In extensive gardens where a number of hands are employed, they are commonly grouped or arranged in divisions, & one of the journeymen of longest standing is employed as foreman to the rest. Wherever 3 or more journeymen are employed, there is commonly a foreman, who has a certain extent of authority at all times, but especially in the absence of the master. This position confers a degree of rank to the garden foreman for the time being, but none afterwards.
Master Gardener. A journeyman has attained the situation of master gardener, when they are appointed to the management of a garden, even if he has no laborer, apprentice, or journeyman under him; but he has not attained to the role of head-gardener till having been a year in such situation. Afterwards should they be obliged to work as journeyman once again, they still retain the rank & title of master-gardener but not of head-gardener.
Head Gardener. A head gardener is a master who has apprentices or journeymen employed under him. Out of a supervising position & working again as a journeyman, they retain the rank & title of master-gardener, but not of head-gardener.
Nursery Foreman. The nursery foreman is entrusted with the numbered & priced catalogues of the articles dealt in; authorized to make sales; entrusted to keep an account of men's time, & as a consequence, this entitles the holder to the rank of head-gardener, while so engaged, & to that of master-gardener ever afterwards; the same may be said of foremen in public botanical gardens & other public gardens.
Traveling Gardener. Traveling gardeners are sent out as a collectors of plants along with scientific expeditions; they are generally chosen from a botanic garden; & their business is to collect gardening productions of every kind, & to record the soil, aspect, & climate..
Botanic Garden Director or Curator. Botanic curators superintend the culture & management of a botanic garden; maintain an extensive correspondence with other botanic curators; exchanges plants, seeds, & dried specimens, so as to keep increasing their garden's collection of living plants & herbarium.
Public Gardener. Gardener employed to oversee the gardens & grounds at a publicly-owned building or a facility operated for the good of the public, such as a church or hospital or institution.
Jobbing gardener. The jobbing gardener makes & tends gardens, & keeps them in repair by the month or year under a contract. Generally they use their own tools, in which they are distinguished from the serving gardener; & sometimes they supply plants from a small scale-garden of their own.
Contract Gardener. Contracting gardeners, or new-ground workmen, are jobbers on a larger scale. They undertake extensive works, such as forming plantations, pieces of water, roads, kitchen gardens, & even greenhouses, hot-houses, & other garden structures & buildings.
Seed Grower. Seed-growers are as frequently farmers as gardeners; they contract with seed-merchants to supply certain seeds at specified rates, or to raise or grow seeds furnished to them by the seedsmen on stipulated terms.
Seed Merchant. Seed merchants sell incidental seeds at their place of business, where they carry other products for sale as well.
Seedsman. A seedsmen deals in garden seeds & other garden products. Generally they combine the seed business with that of nurserymen or florists, but sometimes they confine themselves entirely to dealing in seeds wholesale or act as agents between seed growers & nurserymen.
Herb Gardeners. They grow herbs, either the entire herb, as mint, or particular parts, as the bulb of lilium, & the flower of the rose for medical purposes, or for distillation as perfumery.
Physic Gardeners or Herbalists. They grow herbs for the purpose of medicine, or perfumery, but also collect wild plants for these purposes. Formerly, when it was the fashion among medical men to use indigenous plants as drugs, this was a more common & important branch of trade. Now, they have commonly shops appended to their gardens, or in towns, in which the herbs are preserved, & sold in a dried state.
Collectors for Gardens. The first variety of this grouping is the gipsy-gardeners, who collect haws, acorns, & other berries & nuts, & sell them to the seedsmen; the next are those who collect pine & fir cones, alder-catkins, & other tree-seeds, which require some time, & a process to separate the seeds from their covers, & clean them before they can be sold; & the highest variety are those gardeners who establish themselves in foreign countries, & there collect seeds & roots, & prepare dried specimens of rare plants for sale.
Orchardist. Orchardists of the simplest kind are such as occupy grass-orchards, where they produce is chiefly apples, pears, & plums, for cider or kitchen-use; the next variety occupy cultivated orchard-grounds where fruit-shrubs, as the gooseberry, currant, strawberrry, &c. are grown between the fruit-trees; & the highest variety occupy orchards with walls & hot-houses, & produce the finer stove-fruits & forced articles.
Market or Truck Gardeners. Market gardeners grow culinary vegetables & also fruits; the simplest kind are those who grow only the more common hardy articles for the kitchen, as cabbage, pease, turnips, &c. a higher variety grow plants for propagation, as cauliflowers, celery, & artichoke-plants, & pot-herbs, as mint, thyme; & the highest variety possess hot-beds & hot-houses, & produce mushrooms, melons, pines, & other reed articles & exotic fruits.
Florist. Florists are either market florists who grow & force flowers for the market, & those who grow only hardy flowers to be cut as nosegays, & those who deal chiefly in exotics or green-house plants to be sold in pots. Another is the select florist, who confines himself to the culture of bulbous-rooted & other select or florists' flowers, who has annual flower-shows, & who disposes of the plants, bulbs, tubers, or seeds.
Botanic Gardener. Botanic gardeners devote themselves exclusively to the culture of an extensive collection of species for sale; these may be limited to indigenous kinds. Botanic gardeners also collect & dry specimens of plants, & also of mosses, fungi, alga & offer them for sale: to this they often join the collecting of insects, birds, & other animals.
Nurserymen. Their business is to originate from seed, or by other modes of propagation. Any or every species of vegetable, hardy or exotic, grown in gardens, to rear & train then for sale, & to pack or encase them, so as they may be sent with safety to distant places. The nurseryman is commonly also a seed-grower, & is generally a seed-merchant, supplying his customers annually with what seeds they require for cropping their gardens as well as with the trees they use in stocking them. The simplest variety of nursery-gardener who confines himself to the rearing of hedge plants and forest trees; the highest is he who in addition to all the hardy trees & plants, maintain at the same time a collection of tender exotics.
