Some years ago I grew a number of different mesembs from seed, including Rabiea albipuncta. They all had a common trait, they were possibly winter hardy in my area. I wanted to add South African succulents to my winter hardy beds. Ten plants of R. albipuncta were planted outside, but it wasn't the winter that was their challenge, it was rabbits. The cute little rabbits that hopped around and through my yard seem to have a special fondness for South African succulents and nearly ate them all. Of the 10 Rabieas, only one survived, and I removed it from the bed and potted it up. That was 12 years ago and it is still with me. Now, it's another of my "old friends."
