I didn’t plant it. Presumably it’s courtesy of some birdshit, because I've actually planted seed heads in the yard that failed to germinate. It’s growing in the driveway in 4 inches of gravel on top of 30 years of compacted substrate. I must carefully maneuver around it, which I consider a privilege given the fact that it brightens my every day with its relentless cheer. I've never watered it.
After 10 years gardening on solid rock in Rollingwood, I moved into a 40's cottage in the North Loop area spring 2007. The little postage stamp yard is black clay and no one had ever dug a single flower bed. After visiting Key West a few years ago, I came back inspired by the little frame cottages, white painted railings, and rustling palm leaves. So the plan is: desert tropical cottage garden.
