Agapanthus - recommend cold hardy cvs.

I tried some "hardy" Agapanthus here, in the bed against the west side of 
the greenhouse.  They did not survive the first winter.  I seem to have 
given up on trying them for cold hardiness since then.

I agree with Mary Sue that one must use species from high elevations in the 
Drakensberg, summer growing and deciduous, to have any chance at all of 
having them winter-hardy in USDA cold zone 6 and colder.
