Pellionia Daveanna - 4" PotBotanical Name: Urticaceae Common Names: Trailing Begonia, Rainbow Vines Description: Pellionia, also called "Trailing Begonia" or "Rainbow Vines," has colorful, spectacular leaves that contrast sharply. These plants require frequent misting because they enjoy dampness, or they may be kept in an enclosed terrarium. We advise keeping the soil wet to the touch and placing it under a bright indirect light.
