Found this one a couple of months back, and have had it in a pot since then. Originally this was a cultivated plant, grown for some reason at the Botany greenhouses on campus where I work at UT. My professor, the greenhouse boss guy, can't remember what it is or why he had it though. One thing is certain, it is HIGHLY invasive! I pull this out of almost every pot, crack, and crevice in one of the greenhouses. It is probably an Acanth, maybe a Ruellia. Any ideas? The "regular" form is dark green, purplish backsides to the leaves, and a creeping, prostrate stem. The flowers are very small and a very light pink color, only blooming in the morning.
