Calandrinia spectabilis
Calandrinia spectabilis is a low-growing succulent that produces the most fantastic cloud of bright fuschia flowers you have ever seen, and pretty much year-round.
Here's the first one I saw, at the San Luis Obispo Botanical Garden in June of 2005:
In the Spring of 2006 I bought a small one at the plant sale at the Botanical Garden, and planted it out in front of the roses in the native/xeriscape bed. It immediately began to send up a flower shoot.
May 28, 2006: we have a flower!
