Donkey Tail

I've been trying to remember over the past several days which of my lovely succulents was the one that started the collection.  On one of my trips to Rainbow Gardens, I stumbled on a funny looking thing called a Donkey Tail and I couldn't pass it up.  It's like eating a bag of Lay's...you can't have just one!  I think I can safely say there are at least 50 different little varieties on my back porch, but it all began with this cutie.  He's been trimmed back and shared with friends, but he's still growing strong!
