Rubus idaeus (raspberry, also called red raspberry or occasionally European red raspberry to distinguish it from other raspberry species) is a red-fruited species of Rubus native to Europe and northern Asia and commonly cultivated in other temperate regions.<ref name=fe>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name=grin>Template:GRIN</ref>
TaxonomyEdit
A closely related plant in North America, sometimes regarded as the variety Rubus idaeus var. strigosus, is more commonly treated as a distinct species, Rubus strigosus (American red raspberry), as is done here.<ref name=grin2>Template:GRIN</ref> Red-fruited cultivated raspberries, even in North America, are generally Rubus idaeus or horticultural derivatives of hybrids of R. idaeus and R. strigosus; these plants are all addressed in the present article.
DescriptionEdit
Plants of Rubus idaeus are generally perennials, which bear biennial stems ("canes") from a perennial root system. In its first year, a new, unbranched stem ("primocane") grows vigorously to its full height of 1.5–2.5 m (5.0–8.3 feet), bearing large pinnately compound leaves with five or seven leaflets, but usually no flowers. In its second year (as a "floricane"), a stem does not grow taller, but produces several side shoots, which bear smaller leaves with three or five leaflets. The flowers are produced in late spring on short racemes on the tips of these side shoots, each flower about 1 cm (0.4 inches) diameter with five white petals. The fruit is red, edible, and sweet but tart-flavoured, produced in summer or early autumn; in botanical terminology, it is not a berry at all, but an aggregate fruit of numerous drupelets around a central core. In raspberries (various species of Rubus subgenus Idaeobatus), the drupelets separate from the core when picked, leaving a hollow fruit, whereas in blackberries and most other species of Rubus, the drupelets stay attached to the core. <ref name=fnwe>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name=foc>Template:EFloras</ref><ref name=blamey>Template:Cite book.</ref><ref name=rhs>Template:Cite book.</ref>
BiotopeEdit
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.<ref name=blamey/> The species name idaeus refers to its occurrence on Mount Ida near Troy in northwest Turkey, where the ancient Greeks were most familiar with it.<ref name=rhs/>
Cultivation and usesEdit

R. idaeus is grown primarily for its fruits, but occasionally for its leaves, roots, or other parts.
FruitsEdit
{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}} The fruit of R. idaeus is an important food crop, though most modern commercial raspberry cultivars derive from hybrids between R. idaeus and R. strigosus.<ref name=rhs/> The fruits of wild plants have a sweet taste and are very aromatic.
Leaves and other partsEdit

ChemistryEdit
Vitamin C and phenolics are present in red raspberries. Most notably, the anthocyanins cyanidin-3-sophoroside, cyanidin-3-(2(G)-glucosylrutinoside) and cyanidin-3-glucoside, the two ellagitannins sanguiin H-6 and lambertianin C are present together with trace levels of flavonols, ellagic acid and hydroxycinnamate.<ref>Template:Cite journal</ref>
