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.
