It is generally accepted by researchers and educators in horticultural science that horticultural crops include: tree, bush and perennial vine fruits; perennial bush and tree nuts; vegetables (roots, tubers, shoots, stems, leaves, fruits and flowers of edible and mainly annual plants); aromatic and medicinal foliage, seeds and roots (from annual or perennial plants); cut flowers, potted ornamental plants, and bedding plants (involving both annual or perennial plants); and trees, shrubs, turf and ornamental grasses propagated and produced in nurseries for use in landscaping or for establishing fruit orchards or other crop production units. Sometimes the horticultural plant is used by an animal to produce the crop. Honey is a good example and is often considered to be a horticultural product. Raw silk is produced by silkworms feeding on mulberry trees (which also produce an edible fruit) but silk is not a horticultural crop.
