Hey, Taylor...that variegated Tradescantia isn't THAT unusual, but it is very nice. I've got one also, and so does a friend of mine in Kansas. It will take over, so you have to keep it under control somewhow.
A few more variegates that I've found:
Variegated Solanum ptycanthum. It looks so much better now than in this weeks-old pic!
Variegated Cypripedium reginae. Unbelieveable, really, since this is a very rare plant in TN anyway! But we managed to find a variegated one.
An update on my variegated Catharanthus rosea. It does burn in full sun, but seems to do well in 50% shade. Still needs to be trialed outside. Cuttings have been rooted, so trials will be carried out next year in several spots around the country.
I also have a nicely variegated Physalis longifolia that I haven't taken a picture of yet. Soon!
