I wouldn't call this delightful native "invasive".
I found a patch of croton capitatus growing in a ditch in town... and brought it out to my garden a few years ago...
Everything that I've learned about this plant since then has only increased my appreciation...

The butterfly that uses croton as host plant... (Anaea andria Scudder)
51 species of croton in the United States with 25 species in Texas...
