Some forms of Zenobia pulverulenta have been recognized. Plants with glaucous leaves and twigs occur primarily in the Sandhills region of North Carolina and South Carolina (inner coastal plain); nonglaucous plants occur primarily eastward. Zenobia is cultivated occasionally outside its native range as far north as Massachusetts. It is particularly appropriate for garden areas with wet soil. The flowers are anise-scented.
