Rubus lasiococcus is a North American species of wild blackberry known by the common names roughfruit berry and dwarf bramble.

Description

Rubus lasiococcus is a tangling, prostrate shrub with very slender stolons spreading along the ground and rooting where their nodes come in contact with moist substrate, forming a mat. Some stems grow erect to bear flowers. The leaves are 2.5–6.5 centimetres (1–2+12 in) wide, each deeply divided into three lobes,2 or compound into three toothed leaflets, borne on a petiole a few centimetres long.

The inflorescence is a solitary flower or a pair of flowers with five reflexed sepals and five white petals each up to 1 cm (38 in) long.2 The fruit is a densely hairy red aggregate about 1.3 cm (12 in) across.32

Distribution and habitat

It is native to western North America from British Columbia to northern California, where it grows in mountain forests.456 In the southern half of its range the plant is commonly found in a plant community in the understory of mountain hemlock (Tsuga mertensiana) and Shasta red fir (Abies magnifica var. shastensis).7

Uses

The berry is edible.2
