I just wanted to compliment you on your plants. I received several varieties Bertolonia two years ago in a trade. The ones like you have didn't root but I did have success with two others. One is a large red, the other is green with almost black spots around the edges. These are cool plants it's a shame you don't see them more often.

Hi Dee;

Thank you, though I did take those pictures when the plants weren't at their very best. Do you have pictures of the varieties you are growing? I'm back to seedlings of a few different ones now, but I agree they should be more popular!
