It may be our horrible caliche soil here in central Texas, but I have not found this plant to have spread at all. I quite enjoy something that seems to be quite happy with no supplemental water as well, in the 100 degree heated afternoons!

The flowers attract large amounts of hawkmoths at night. The flowers also smell wonderful at dusk! The plant get to 3 1/2' high and develop underground what looks like a black yam at the end of the season. Of which can be lifted like a dahila and stored. Love the plant.
