Best planted in early spring after your last frost, or in fall before the ground freezes, depending on your climate.

Grown chiefly as a foliage plant rather than for its fruit — an arching evergreen Himalayan shrub with large, glossy, deep-green leaves that are silvery beneath and finely veined. Claret-red flowers in summer are followed by orange-red fruit in autumn; it benefits from shelter from cold winds at the cooler edge of its range.

Growth speed
Fast — canes make 1–3 m in a season
Spacing
150 cm (59 in) apart — about 2.3 m² (24 sq ft) per plant
Leaf shape
Large, glossy, deep-green leaves, silvery on the underside, with numerous closely spaced parallel veins — the plant's main ornamental feature.
Root system
A perennial crown and shallow spreading root system in the top 30–40 cm, carrying biennial canes: each cane grows one year, fruits the next, then dies. New shoots come from buds on both the crown and the roots, which is why a bramble returns from root fragments left after digging and why it is so hard to remove once settled.
Fruit description
Orange-red fruit produced in autumn, following claret-red summer flowers — an aggregate fruit typical of the genus, though little is documented on its size or flavor.
Propagation
Tip layering is the natural method for the trailing kinds: bury a cane tip in late summer and sever it once rooted. Erect kinds sucker freely and a rooted sucker can simply be lifted. Root cuttings in winter also work. Seed needs a long cold stratification and is slow.
Pollination
Self-fertile

Growing guide

Growing tips. Valued in cultivation mainly for its handsome, deeply veined evergreen foliage rather than for its sparse fruit; give it shelter from freezing winds, since cold, drying exposure is its main limiting factor outside its Himalayan cloud-forest origin.

About the data

Zone figures are typical published ranges — microclimate, drainage and siting shift them by a zone in either direction. Store links are found by an automated search, refreshed every six weeks. Availability is seasonal; stock and prices are not tracked.
