It’s a perennial herb that generally grows from 10 to 16 inches tall and has winged stems. There may be 10 or more stems on one plant. White irisette flowers from late May through July. The seeds are very small and black; and three to six seeds are contained in each capsule.
It’s is found on mid elevation slopes, characterized by open, dry to moderate-moisture oak hickory forests. White irisette usually grows in shallow soils on regularly disturbed sites (such as woodland edges and roadsides) and over rocky, steep terrain.
