Known for its large clusters of dark purple to almost black flowers, Black Jade Vine blooms in grapelike clusters. The magnificent floral cluster can reach 1 in length with a 6 diameter. It blooms in winter and early spring. This fast growing vine needs lots of room so it is best to grow on a trellis for support or use a hanging basket and let the plant spill over the edge. Planted in the ground in southern zones, this vigorous vine can reach up to 50 long. Black Jade Vine is a rare plant and we have a limited supply. Order early.
