Flowers change to tiny fruits with even tinier black seeds. One plant has thousands of seeds.

Lamb's Quarters grows just about anywhere, especially roadsides, streambanks, gardens, lawns, and waste places.

This plant was introduced from another country and is very competitive with native plants.

Lamb's Quarters is an annual plant, which means it dies when the weather gets cold.
