I'm interested in hearing growing experiences with this series from mid-western gardeners.
I've tried several selections here in my nursery - north-east Kansas - over the past two years. Whether growing in the ground, or over-wintered in containers, they have not survived winter worth a spit.
Altho they are being sold in every garden center and big box store in the area, I'm giving up on them. If I can't make them work, I don't expect my customers to have much luck, and I'm just not gonna sell them any longer.
Nonetheless, perhaps other folks in the mid-west are having great success with them - if so, I'd love to hear of it!
