It's a Mesembryanthemum. I've seen the variegated ones, but have only grown the green varieties. There are a lot in the database here on All Things Plants. If you do a search and go through all the entries you might be able to narrow down which ones are possibilities for the one you have. They are attractive plants when well grown and not too hard to grow. I'm going to have to find some way to hang mine because my cottontails, jack rabbits and squirrels have developed a taste for it and I can't keep it looking good! Beware of the squirrels if you have them!
