Slightly hairy stems may be simple or branches and have several tiny lavender or blue-violet flowers in terminal, leafy, elongated clusters.

This acrid poisonous annual is found in a variety of sites, often in poor soil. The American Indians were said to have smoked and chewed its leaves; hence the common name. Though once used as an emetic, the root should not be eaten, for if taken in quantity it can be fatal.
