The Rhoeo discolor or Tradescantia spathacea, is a great addition to any grassland or rainforest BioActive enclosure! This plant is known for its attractive green leaves and purple underside. Unlike most of its cousins or members of the Commelinaceae family, the Rhoeo isn't an invader. It can form a clump but doesn't have the stolons that allow other Tradescantia to spread.
