Rubus idaeus

Biggest Plant Dictionary  | Rubus idaeus | Rosaceae Rubus idaeus perennial shrub native to north-central Europe sarmentosa, stump consists of small size, long shoots that grow with the construction of two years, covered by a thin hair, sometimes spiny, curved and flexible, growing to 150 - 200 cm. In the spring produces small white flowers pink, at Inflorescences pyramidal, some varieties produce fruit in summer, the branch of the year, other varieties produce fruit on branches a year in spring and summer, feeding on new shoots.

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, 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 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.

As a wild plant, Rubus 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 only occurs at high altitudes in mountains.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.

Culinary uses Close
Fruit - raw or cooked. Delicious when eaten out of hand, the fruit is also used in pies, preserves etc. Root - cooked. The root, which should be neither too young nor too old, requires a lot of boiling. Young shoots - peeled and eaten raw or cooked like asparagus. They are harvested as they emerge through the ground in the spring and whilst they are still tender. A herb tea is made from the dried leaves. Another report says that a type of tea made from raspberry and blackberry leaves is an excellent coffee substitute.
