I'm always looking for new food sources that I can grow for my tortoises, I have been trying to find cold hardy succulents from Africa, no luck yet. But I did find this one, Kalanchoe Luciae, native to South Africa.It's not hardy but gets big, grows pretty quick under the right conditions, and throws off baby plants like the hens and chicks. I am mainly thinking about my leopard tortoise.Since succulents are native to Africa and cactus is not maybe they are what they ate before cactus was introduced. Anyone ever offered these to a leopard tortoise? Len
