Horticulture is the cultivation of plants in gardens or greenhouses, as opposed to the field-scale production of crops characteristic of agriculture. It includes the cultivation of fruits, vegetables, nuts, seeds, herbs, sprouts, mushrooms, algae, flowers, seaweeds and non-food crops such as grass and ornamental trees and plants. It also includes plant conservation, landscape restoration, landscape and garden design, construction, and maintenance, and arboriculture, ornamental trees and lawns.
Forsythia, is a genus of flowering plants in the olive family Oleaceae. There are about 11 species, mostly native to eastern Asia, but one native to southeastern Europe. Forsythia – also one of the plant's common names – is named after William Forsyth.
Arboriculture is the cultivation, management, and study of individual trees, shrubs, vines, and other perennial woody plants. The science of arboriculture studies how these plants grow and respond to cultural practices and to their environment. The practice of arboriculture includes cultural techniques such as selection, planting, training, fertilization, pest and pathogen control, pruning, shaping, and removal.
Vegetative reproduction is any form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cutting of the parent plant or specialized reproductive structures, which are sometimes called vegetative propagules.
Variegation is the appearance of differently coloured zones in the leaves and sometimes the stems and fruit of plants. Species with variegated individuals are sometimes found in the understory of tropical rainforests, and this habitat is the source of a number of variegated houseplants. Variegation is caused by mutations that affect chlorophyll production or by viruses, such as mosaic viruses, which have been studied by scientists. The striking look of variegated plants is desired by many gardeners, and some have deliberately tried to induce it for aesthetic purposes. There are a number of gardening books about variegated plants, and some gardening societies specialize in them.
Plant propagation is the process by which new plants grow from a various sources, including seeds, cuttings, and other plant parts. Plant propagation can also refer to the man-made or natural dispersal of seeds.
A perennial plant or simply perennial is a plant that lives more than two years. The term is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth from trees and shrubs, which are also technically perennials.
Sanguinaria canadensis, bloodroot, is a perennial, herbaceous flowering plant native to eastern North America. It is the only species in the genus Sanguinaria, included in the poppy family Papaveraceae, and is most closely related to Eomecon of eastern Asia.
Layering is the process whereby the branch of a tree, or other plant, produces roots and is separated from the original plant, becoming a new, separate plant. Layering is utilized by horticulturists to propagate desirable plants.
A plant cutting is a piece of a plant that is used in horticulture for vegetative (asexual) propagation. A piece of the stem or root of the source plant is placed in a suitable medium such as moist soil. If the conditions are suitable, the plant piece will begin to grow as a new plant independent of the parent, a process known as striking. A stem cutting produces new roots, and a root cutting produces new stems. Some plants can be grown from leaf pieces, called leaf cuttings, which produce both stems and roots. The scions used in grafting are also called cuttings.
Streptocarpus is an Afrotropical genus of flowering plants in the family Gesneriaceae. The genus is native to Afromontane biotopes from central, eastern and southern Africa, including Madagascar and the Comoro Islands. The flowers are five-petalled, salverform tubes, almost orchid-like in appearance, and hover or arch over the plant, while the pointed, elongate fruit is of a helical form similar to that of the "tusk" of a narwhal. In the wild, species can be found growing on shaded rocky hillsides or cliffs, on the ground, in rock crevices, and almost anywhere the seed can germinate and grow. For the home, there are now many hybrids of various colours and forms available.
"Liners" is a horticultural term referring to very young plants, usually grown for sale to retailers or wholesalers, who then grow them to a larger size before selling them to consumers. Liners are usually grown from seed, but may also be grown from cuttings or tissue culture. They are grown in plastic trays with many "cells," each of which contains a single liner plant. Liners will typically range in size from a 36 cell tray up to a 288 cell tray. The most common size used in commercial nurseries is between 50 and 72 cells. The term "liner", is typically used for perennial, ornamental, and woody seedlings. Annuals in this form are usually referred to as plugs.

Echinacea purpurea, the eastern purple coneflower, purple coneflower, hedgehog coneflower, or echinacea, is a North American species of flowering plant in the family Asteraceae. It is native to parts of eastern North America and present to some extent in the wild in much of the eastern, southeastern and midwestern United States as well as in the Canadian Province of Ontario. It is most common in the Ozarks and in the Mississippi/Ohio Valley. Its habitats include dry open woods, prairies and barrens.
Hibiscus mutabilis, also known as the Confederate rose, Dixie rosemallow, cotton rose or cotton rosemallow, is a plant long cultivated for its showy flowers. Originally native to southern China, it is now found on all continents except Antarctica.
Aurinia saxatilis is an ornamental plant native to Asia and Europe.
Grafting or graftage is a horticultural technique whereby tissues of plants are joined so as to continue their growth together. The upper part of the combined plant is called the scion while the lower part is called the rootstock. The success of this joining requires that the vascular tissues grow together. The natural equivalent of this process is inosculation. The technique is most commonly used in asexual propagation of commercially grown plants for the horticultural and agricultural trades. The scion is typically joined to the rootstock at the soil line; however, top work grafting may occur far above this line, leaving an understock consisting of the lower part of the trunk and the root system.
Anaphalis triplinervis is an Asian species of flowering herbaceous perennial plant in the family Asteraceae, native to the Himalayas. Grey-green felted leaves produce sprays of small white flower heads.
Maranta leuconeura, also known as prayer plant, is a species of flowering plant in the family Marantaceae, native to the Brazilian tropical forests. It is a variable, rhizomatous perennial, growing to 30 cm (12 in) tall and broad, with crowded clumps of evergreen, strikingly-marked oval leaves, each up to 12 cm (5 in) long.
Gardening Naturally is a TV show series hosted by Barbara Damrosch and Eliot Coleman. It was created from 1993 to 1994 and ran until about 2003. It first aired on TLC and later reruns were shown on Discovery Home and Leisure.
