A nursery is a place for growing young saplings under predetermined environmental conditions. These saplings are then sold or planted elsewhere.
Commercial nurseries produce and distribute plants including herbaceous, woody, ornamental trees. While most of the plants grown in the nursery are ornamental, also included are fruit plants and some types of perennial vegetables used in home gardens.
There are different types of nurseries that specialize in different types of plants such as edible crops. Other nurseries focus on woody plants like trees and shrubs. Some species are grown from seeds, stem cuttings, or grafting in the controlled setting of a greenhouse. These seedlings are grown in a nursery to transplant to other fields.
Plants such as orchids require that their environments have very controlled humidity and temperature levels. Most often a nursery will concentrate solely on the cultivation of those specific plants.
