Description: Lamb’s Quarters is an annual herb that grows 2’-7’ and is usually much-branched. The spear-shaped leaves are 1”-2” long. The upper leaves have complete (entire) edges; the lower are toothed (dentate). New growth is densely white-mealy, and older growth is more or less mealy throughout. Its tiny flowers are densely clustered in spikes to form an upright or slightly spreading panicle, which is a loose branch that contains the seed heads. Lamb’s Quarters is edible–certain varieties are grown for their leaves and soft stems and eaten as a vegetable. Lamb’s Quarters is cross-reactive with Kochia, Greasewood, and Beet.
