The Raspberry or Red Raspberry, (Rubus idaeus) is a plant that produces a tart, sweet, red composite fruit in late summer or early autumn. The fruit is not a true berry but a cluster of drupelets around a central core. In raspberry and other species of the subgenus Idaeobatus, the druplets separate from the core when picked, leaving a hollow fruit, whereas in blackberry the druplets stay attached to the core.
It typically grows in forest clearings or fields, particularly where fire or wood-cutting has produced open space for colonization by this opportunistic colonizer of disturbed soil. As a cultivated plant in moist temperate regions, it is easy to grow and has a tendency to spread unless cut back. Raspberry is sometimes eaten by the larvae of some Lepidoptera species including Emperor Moth, Peach Blossom, The Engrailed, Small Square-spot and Double Square-spot.
Two types are commercially available: the wild-type summer bearing, that produces an abundance of fruit on second-year canes within a relatively short period in midsummer, and double- or "ever"- bearing plants, which also bear a few fruit on first-year canes in the autumn, as well as the summer crop on second-year canes. Raspberries can be cultivated from USDA plant hardiness zones 9 to 3.
A gold raspberry, which is pale yellow, has been selected by horticulturalists.
The black raspberry, also called a blackcap, is not the same plant, being a cultivar (usually) of Rubus occidentalis, a North American species. Other Rubus species also called raspberries include:
- Arctic raspberry (Rubus arcticus)
- Flowering raspberry (Rubus odoratus)
- Wine raspberry (Rubus phoenicolasius)
- Whitebark raspberry or Western Raspberry (Rubus leucodermis)
Not all of these are included in the same subgenus.
