The Himalayan blackberry is capable of extensive and vigorous vegetative regeneration. Sexual reproduction may also be important. Reproductive versatility is well represented in the Rubus genus, with sexual reproduction, parthenogenesis (development of the egg without fertilization), pseudogamy (a form of apomixis in which pollination is required), and parthenocarpy (production of fruit without fertilization), occurring widely. The following types of reproduction have been documented in blackberries: (1) sexual reproduction, (2) nonreduction at meiosis on the female, male, or both sides, (3) apomixis (seeds contain embryos of maternal, rather than sexual origin) with segregation, (4) apomixis without segregation, and (5) haploid parthenogenesis. These modes of asexual reproduction contribute significantly to the aggressive, vigorous spread of blackberries.

Vegetative regeneration- The mostly biennial stems of blackberries typically develop from perennial rootstocks or creeping stems. Most species within the Rubus genus are capable of sprouting vigorously from root or stem suckers, or rooting stem tips. Although not specifically documented for the Himalayan blackberry, a similar response is probable given the plant's morphology and the speed at which postdisturbance establishment and spread occurs. The Himalayan blackberry is known to spread extensively by trailing stems which root at the nodes. Rapid vegetative spread occurs even in the absence of disturbance.

Seed production- Immature fruit of the Himalayan blackberry is red and hard, but at maturity, fruit becomes shiny black, soft, and succulent. Individual drupelets form an aggregate up to 2 cm in length. Cleaned seed averages approximately 323,789/kg.
