Rubus lasiococcus

Rubus lasiococcus A. Gray

Roughfruit Berry, Dwarf Bramble

Rosaceae (Rose Family)


USDA Symbol: rula2

USDA Native Status: L48 (N), CAN (N)

Trailing, thornless, freely rooting, leafy stems and short erect stems bearing 1 leaf and 1-2 white flowers.

Rubus comes from the Roman word for “bramble”; species of this large and complicated genus are more often shrubs or formidable patches of thorny brambles than low creepers. There are perhaps 15 Rubus species throughout the West, variously called blackberries, raspberries, or thimbleberries. Through hybridization and selection, many horticultural varieties have improved the berries. However, berries found in the wild are equally sweet, juicy, and flavorful.
