Tolerant to heavy soil and drought. Developed in Australia, the Silvanberry is a result of crossbreeding between the Marion berry and a hybrid of Pacific and Boysenberries. Belonging to the blackberry family, Silvanberry plants exhibit several characteristics commonly seen in other blackberry varieties. These plants are enduring perennials, capable of living for 15 to 20 years, resilient against cold climates, easy to cultivate, and known for their prolific spreading tendencies. To manage their enthusiastic growth, it is advisable, as with other blackberry types, to confine Silvanberry fruit plants within a pot or planter box with a trellis or by positioning them against a fence.
