Silver bells™ Chocolate Vine Bears Sweet-Flavored Fruit and Smells Like Chocolate! This 15- to 20-ft. vine smells like dessert, & produces loads of lovely lilac-purple flowers from May through June. It bears unique, leathery leaves that grow in attractive clusters and are evergreen in milder climates. Can be used as a climber on arbors, trellises & fences or as a lush ground cover. Large, edible seedpods ripen in early autumn & taste like tapioca pudding! Plant two varieties for pollination.
