Aren't these wild? Lithops are a type of ice plant from South Africa. Living stones flower in the fall during October and November, so ours are flowering right now!
Those things that look like toes are the leaves, and the flower pokes up in between the two halves. After flowering, the old leaves shrivel up and completely replaced by two new leaves.
We have a "How to Care for Lithos" pamphlet available at the shop, and the instructions are pretty simple. You mist them with water once every two weeks during the winter months and then in the spring you start misting once a week until it flowers in fall. This is a great gift for kids and grownups alike!
