First up: aeonium tabuliforme (left). These wonderful aeoniums usually grow flat against the ground, like lily pads. I love the texture. They occur in crested form, too.
Supposedly there's no common name for these, but I think they should be called "green book stacks." Don't they look like a stack of tomes with the spines facing you? The bigger they get, the more they look like a mountain of books!
At left is a picture I look at the Succulent Extravaganza at Succulent Gardens in Castroville, CA last month. They had a whole row of these, planted above a huge bed of blue glows. The effect was awesome. Blue flames look like living sculptures, and the color is intense!
So those are just a few of the plants at the top of my list. As you can guess, there are plenty of others (and don't even get me started on crested and variegated forms--drool!) Now I want to know what plants are at the top of yours. Come on, succ-ers--let's hear it!
