Cinta, Love that purply one! I've never tried Tradescantia or Callisia as indoor house plants, I just don't have enough room inside so they get planted in the ground here. I used to have a garden bed with Variegated Oyster Plant (Tradescantia spathacea 'Sitara') and liked it a lot but lost it to winter freezes. I love the looks of these also but have never seen them for sale here: Inch Plant (Tradescantia mundula 'Lisa')
