American Red Raspberry
Rubus idaeus
  
About American Red Raspberry (Rubus idaeus) 1 Nurseries Carry This Plant Rubus idaeus (Raspberry; occasionally as European Raspberry, Framboise, or Red Raspberry to distinguish it from related species) is a species of Rubus, native to Europe and northern Asia. A closely related plant in North America, formerly often regarded as a variety Rubus idaeus var. strigosus, is now usually treated as a distinct species Rubus strigosus (American Raspberry). It is a perennial plant which bears biennial stems ("canes") from the perennial root system. In its first year, a new stem grows vigorously to its full height of 1.5-2.5 meter, unbranched, and bearing large pinnate leaves with five or seven leaflets; normally it does not produce any flowers. In its second year, the 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 centimeter diameter with five white petals. The fruit is red, edible, 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 raspberry, as in other species of the subgenus Idaeobatus, the drupelets separate from the core when picked, leaving a hollow fruit, whereas in blackberry the drupelets stay attached to the core.
