This plant went through many days of 100+ temperatures without wilting, I call this a heat and drought tolerant plant.

Clammyweed is a host plant for Florida White (Appias drusilla) & Great Southern White (Ascia monuste) butterflies & is a great nectar plant for swallowtails as well as other butterflies.
