White turtle-head is an upright, vase-shaped plant that carries white flowers tinged with pink over thick, dark green leaves. The hooded flowers bloom at the end of the stems in late summer to early fall. The plant likes consistent moisture and can tolerate wet soil, so it is useful near the edges of streams or ponds.
This species is native to the Chicago Region according to Swink and Wilhelm’s Plants of the Chicago Region, with updates made according to current research.
