ℹ️ Considered to be one of the most delicious wild berries in existence! Wild Blackberry is a vigorous trailing thorny shrub with three to five leaflets, large white flowers in spring that are very attractive to bees, and delicious fruits that go from red to purple-black when ripe in August through September. Consider using a trellis when growing in the garden to allow this plant to climb to facilitate easy harvest. Wild Blackberry, also called brambles, provide important sources of food and cover for many birds and mammals.
