Blackberry is a very prickly, rambling vine. Grows in thickets <2m tall formed by arching stems or canes 7m long. It has dark green shiny leaves which are normally shed in winter. It has pink/white flowers (November to April) and produces edible blackberries. It develops dense canopy cover in short time. Dominates native flora in swamps and pasture use and access are reduced. It spreads vegetatively via lateral suckering & from daughter plants. Seeds are spread by birds & waterways. The problem with blackberry is that it has an extensive rhizome system which can be difficult to get rid of. While the top part of the plant may be removed, the problem still exists if the rhizomes are left in the ground, hence blackberry control can be difficult. Dense thickets of blackberry of up to 2 metres tall can prevent stock and human access as well as providing refuges for other pests like possums and rabbits.
