Folklore

Samuel Johnson's dictionary of 1755 defined oats as a grain given to horses in England that in Scotland supports the people, and a Scot is said to have answered that this was why England had such fine horses and Scotland such fine men. Feeling your oats began as stable talk for a frisky, well-fed horse. Eclectic physicians of the late 1800s gave fresh oat tincture to patients worn down by exhaustion and to people coming off opium.

How to grow

Sow in early spring as soon as the soil can be worked, in full sun. About two months later, check the heads daily; the milky stage lasts about a week, when a pinched seed bursts white. Cut the green straw after the milky harvest.

In the wild

Cultivated oats descend from a weed of Near Eastern wheat and barley fields, and wild oat (Avena fatua) still follows grain crops around the world.
