Rubus deliciosus (Boulder Raspberry or Delicious Raspberry) is a deciduous shrub native to the United States, in the Rocky Mountains in Colorado, New Mexico, western Oklahoma (Cimarron County only), and Wyoming. It inhabits scrub and rocky slopes.[1][2]
It is a deciduous shrub or vine growing to 1.5 m (rarely to 3 m) with arching stems; unlike many species of Rubus, the flowering stems are perennial. The bark is flaky and peeling. The leaves are simple (not compound, like most other species in the genus), 3.3–5 cm long and broad, with three shallowly rounded lobes (occasionally unlobed or five-lobed), becoming glabrous beneath. The flowers are 3.8–6 cm diameter, fragrant, with five white petals 1.5–3 cm across. The fruit is dark red, 10–13 mm diameter; it is rather dry and not highly valued, but the flavor is delicious.[2][3][4]
[edit] Cultivation
Requires well drained soil in full sun. Hardy to USDA zone 5 (-20°C). It is propagated by cuttings in July or August.[4]
It has hybridized in cultivation with the very closely related (and possibly conspecific) Rubus trilobus of southern Mexico. Two cultivars of this parentage have been selected, 'Benenden' and 'Margaret Gordon'; they are popular ornamental plants in gardens, having larger flowers up to 8 cm diameter.[5]
