I have never sen them sold by the clump before. They look great and if I needed any I would buy them this way. These are very tough plants and I would not be concerned about them growing. Al

so do you think that if I got a clump like these above, they could easily be divided? I"m just debating about how much to spend and if I can divide them easily I"ll just buy less even if it means waiting longer for them to develope and bloom, etc.

They look to me like they would be very easy to divide just fine.

NOW dont you all go running over there to buy all these before I get mine ;)
I promise not to, since they are not hardy here, or for that matter even in your zone according to the site.

Touch of Nature claims the varieties they carry are hardy in zone 3-9. hhhhmmmm.........

I intend to put them in large pots that can winter in my greenhouse.

Hardiness:
Zones 9-11, elsewhere dig in fall and store indoors
