I apologize for this delayed reply to your gardening question and hope it is still helpful to you.
Natal plum is pretty iffy in that area. It may be worth a try if you feel the site is somewhat protected but I would not consider it an option. Other plants to consider are dwarf gardenia which would need some soil amending with peat to give it a better start, dwarf yaupon, and dwarf chinese holly (sharp points on foliage).
Thanks for the question. Best wishes for a wonderful gardening year in 2007. Please stop in again soon!
