I bought 3 Kaffir (Bush) lilies recently that were grown at a Charleston area nursery. The tag info stated they were cold hardy to zone 8, but when I got them home and checked with DG planfiles, I learned they're only cold hardy to zone 9b. Has anyone out there in zone 8a had any luck growing this lily in ground year round? I posed this question in the Carolina forum, but only I got one response from a zone 9a gardener who was successfully growing it outdoors year round in a container. Also, just curious, when did Atlanta's climate zone change to 8b?
