Well that's interesting. I just bought a pack of snow-on-the-mountain seeds. I thought Euphorbias were perennials, at least all the ones I have are. So I guess I'll need to treat these a little differently than I thought. They sure are pretty and I bet the wildlife will leave them alone too. I have deer, rabbits, gophers, wood rats, tree rats, and mice all eating my garden up. The plants that do best are non-edible.
