characteristics

This circumpolar perennial plant is not a grass nor does it look like a grass. (Why it is called a grass is a mystery.)

At the plant's base are a rosette of spade-shaped leaves. Long stems with a clasping leaf midway give the impression the stem is growing out of the leaf. A single white flower with green-yellow translucent veins blooms at the stem's tip. At the flower's centre are a cluster of yellow stamens and infertile stamen-like nectar glands that are inviting to pollinators.
Also known as fen grass of parnassus, American grass-of-Parnussus, and bog-stars.
