Not sure what you are looking for, but there was an article in the LA Times a few weeks back about red sprouts.

And I know Territorial Seed carries seed for the variety Rubine. I'm thinking about trying them out strictly for the novelty. When you cook them, they're supposed to retain their color, unlike purple cabbage which turns a horrid shade of blue-grey

I grew Falstaff two years ago and was quite satisfied with them. They got rather a late start, but I harvested all I wanted before the deer and rabbits finished them off mid winter. They were pretty sweet with kind of a nutty taste. I'll definitely grow them again. They are quite attractive w/a nice bronze color.

Both Falstaff and Rubine are a fun novelty plant to grow. The only real "problem" with either kind, IIRC, is that both seemed to throw a lot of "off type" plants that had open, fluffy, fairly useless sprouts, and weird growth habits -- I guess maybe because both are open pollinated heirlooms (I think). I grew I think Rubine in 2008, and actually had a number of them, like 4 or 5 out of maybe 15-20 plants, that got as tall as the rest, but instead of making sprouts up and down the stems, actually made a large, cabbage type head at the top -- kind of funny, but still edible and useful.
