syngoniums:

Frerea indica, a succulent asclepiad from western India. It grows leaves during the monsoon season in its native habitat. Normally flowers are five-sided, not four.

Not sure if Texas fall rains are throwing it off, but it’s budding up like crazy now. It may have to become a houseplant come winter if colder weather doesn’t knock it into dormancy soon. (I hope not because it just screams spider mite magnet, but I guess that will trigger leaf loss if nothing else does, lol.)
