They are quite tender, not suited for Zone 8.

Thank you. They are so gorgeous I was hoping against doubts that I would be able to grow it.

You can grow them there - you just have to bring them inside when it gets cold. Soon the migratory schlep to the interior of the Interior will begin for me. You'll find you get normal growth even in winter, as long as conditions are suitable (e.g. sun, warmth, water).

They aren't heavy and might be easy to move on that score, but they can reach 7' across, so you'd better have some room! ;-)

That's the problem. I just don't have an inch to spare in my small overwintering house. But I can dream -- can't I? :-)
