Description of Plant(s) and Culture

Oat is an annual grass; a fibrous root produces a hollow, jointed stem from 2-4 feet high with more or less rough, pale green, narrow, flat leaves. The flowers are arranged in a loose terminal panicle from 6-12 inches long which usually consists of 2-4 flowered spikelets from 3/4 to 1 inch long. The hairy, grooved grain is narrow, with almost parallel sides.

Other varieties: The Chinese oats (A. fatua) is called Yen-mai. Seldom cultivated in China; the wild variety is sometimes harvested in times of dearth and is used in making bread.
Wild oats (Uvularia sessilifolia L.) is a perennial plant 6-12 inches tall.

Leaves are sessile, not surrounding the stems; glaucous beneath. The stem is forked about 2/3 of the way up from the ground. Flowers are pale, straw-colored bells, blooming in May to June. Wild oats are of the lily family and the roots are used medicinally. Native Americans used the root tea to treat diarrhea, and as a blood purifier. Internally, taken to aid in healing broken bones. Externally, poulticed for boils and broken bones. The root was a folk medicine for sore throats and mouth sores; said to be mucilaginous (slimy) and somewhat acrid-tasting when fresh.
