Cissus Discolor, aka Rex Begonia Vine, is not actually related to a Begonia in any way but its foliage bears a striking resemblance to a Rex Begonia. The elongated, heart-shaped leaves are a deep green with silvery patches between the veins and rich, burgundy outer margins and undersides. The velvety texture is just the cherry on top! The burgundy vines will send out little tendrils to latch onto any nearby structures, allowing the plant to either trail or climb.
