I plant them every year here, and some of them do come back each year, but not all make it through the winter. Of course I'm farther north than you. They root really easily from cuttings too. In fact, you can cut a section off and just stick it in the ground and it'll root. So if you start with a couple of plants, you can cut the runners and root them and have lots of plants during the summer. I love the bright yellow green colors too and they also grow well in light shade for me. I use them in containers too.

Thanks, Jan, for the reply. I am fond of the chartreuse variety for its vigor. I like the burgundy one, but it is definitely not as showy, being harder to see, but the leaf shape is like a shark tooth, very pointed. Just think, if I had tried to save all those trimmed ends, I could cover half of Mobile by now. Next year, I think I'll try those in the rock flower beds bordering the grotto at my church.

This spring I couldn't find a variegated one, so planted one chartreuse one and one burgundy one together to cover the old stump rotting in our front yard. I've had to cut them both back (particularly the chartreuse one), but I interwove them as they grew and it looks great.
