Tom blogged about a starfish cactus today. I've never seen it before, but it's pretty cool looking. I'm not a fan of cacti (except for Christmas cactus) and succulent gardening, but it's becoming more and more popular as people are on water restrictions.
Here's a picture of the succulent garden at Kanapaha Botanical Gardens. It's bigger than what most people would do, and not my taste, but still cool.
