I saw a picture on Facebook, and followed the link to one of the most interesting garden sites I've come on in a long time, Simply Succulents http://www.simplysucculents.com/simply-succulents-nursery
Simply Succulents is a nursery and online store, among other things. They apparently specialize in succulents, and use them with an artistry that is inspirational. At least to me! I researched some more about succulents as art, and came on a Martha Stewart article along the same line. It turned out to be Simply Succulents that was featured. If you can impress Martha, you are good.
