aka African Milk Bush
A great drought tolerant plant known by many names and introduced to me as an African Poinsettia.
I initially did not have a lot of success with this plant, but since planting it under a live oak, where it gets Summer shade and Winter sun, it's been thriving so long as I water it regularly.
Its leaves look soft but are oddly rubbery to the touch. It can be grown into a small bush or is suitable for container planting. It's also easy to propagate by rooting cuttings taken in Spring or Summer.
This plant has many common names. What do you call it?
