largeflower Mexican clover, Richardia grandiflora

Largeflower Mexican clover? The flowers are about a half inch long. It's from South America. And it's not a clover. But the flowers are larger than it's relatives. Mexico? South America? They're pretty close, aren't they? And it came here to do lawn jobs that clover doesn't really want to do in Florida. I have to confess I didn't check my model's green card. A relative newcomer, you will find it in Florida lawns and weedy places that are without chemical walls. Polk Co FL, 10/21/15.
