 If you look on the map, the growing zone would tell you that I'm in growing zone 6, but frankly, the environment that I have, we've got a fairly hilly piece of property, and so that topography kind of puts me in a zone 5, which makes it a lot harder. A lot of these plants are hardy to zone 6. The plant is hardy, but the stem needs to be hardy to zone 6, and that's where the challenge comes in.
