A cactus family

I really thought that we were having a lot of rain in June and July. In fact, a month or two ago I thought we were having a particularly wet winter. Apparently not. Apparently it seems as though we should all consider removing our pretty flowering plants and replacing them with prickly drought-resistant cacti.

According to the South African Cactus Pear Growers Association cacti were once used as a barrier to protect crops from wild animals. Perhaps we could replace our high fences and security gates with a few cactus plants? What do you think? ;)
