Biotope

As a wild plant, ''R. idaeus'' typically grows in forests, forming open stands under a tree canopy, and denser stands in clearings. In the south of its range (southern Europe and central Asia), it occurs only at high altitudes in mountains. The species name ''idaeus'' refers to its occurrence on

Cultivation and uses

''R. idaeus'' is grown primarily for its fruits, but occasionally for its leaves, roots, or other parts.


Fruits

The fruit of ''R. idaeus'' is an important food crop, though most modern commercial raspberry
