Description

Himalayan blackberry is a European species of perrenial deciduous shrub now widespread in North America. It is common in the mountains of North Carolina and occasionally found on the Piedmont and coastal parts of the state. The species is pollinated by insects, or more commonly, propagated with rooting canes (branches). It grows well in full sun or light shade and in most soils (sandy, loamy, or clay). It prefers well-drained loamy soil. The fruit is edible, but not as useful for that purpose as other species of blackberry. This blackberry has biennial stems, that is, it produces a number of new stems each year from the perennial rootstock that fruit in their second year and then die. The plant produces apomictic flowers, these produce fruit and viable seed without fertilization, each seedling is a genetic copy of the parent.
