White Grained Mountain Rice

White Grained Mountain RiceOryzopsis asperifolia Michx.

White Grained Mountain Rice is one of the earliest of the woodland grasses, and the common name refers to the large seed of which it is said that a white flour has been made.

The tufts of long basal leaves remain green during the winter, and in early spring the slender stems rise (often purple-tinged at the base) bearing short, narrow panicles of a few pale-coloured fiowers.
