Commonly grown, but as yet uncommon as an escape to disturbed, open sites, though first collected in 1929 in Wayne Co.
This species is not colonial, but forms dense clumps from hard, knotty, compact rhizomes. Spread seems mostly by seed. A collection from a dump in Berrien Co. is the variegated leaved cultivar ‘Zebrinus,’ likely established from garden refuse.
