About

Chenopodium album is a rapidly growing annual that can reach heights of up to 2 meters. The plant features upright, branching stems and has silvery-green leaves that are slightly toothed; these leaves become narrower as they ascend the plant and have a mealy white underside. It produces spikes filled with small, densely packed green flowers, each capable of yielding thousands of seeds.

About the genus

Chenopodium includes both annual and perennial species, characterized by stems and leaves that may have a mealy texture. The leaves can be either simple or lobed, and the plant produces small flowers that appear in clusters at the ends of branches or in the leaf axils. In some species, these flowers are succeeded by colorful fruits.
