Discussion

It is questionable whether var. drummondii is native to states east of Texas. The remarkably uniform populations that grow in central Texas suggest that the variety is native there. The taxon apparently was, early on, taken into cultivation in coastal southeastern United States, where it has escaped and persisted. Variety drummondii is also grown in California, North Carolina, and South Carolina but has not naturalized.
