Kochia, Kochia scoparia L., native to Eurasia, is an annual plant that reproduces from seeds. It has a deep taproot and network of fibrous roots. Mature plants typically range from one to four feet tall, but can grow several feet taller.
Kochia is bushy with multiple branches of finely textured linear foliage that turns red in the fall. The leaves are alternate, simple, stalkless, 1 to 2 inches long, and fringed with hair. Flowering occurs from July to October. The flowers are small, green and inconspicuous and are found in clusters in the axils of upper leaves and in short, dense spikes. Seeds are short-lived, brown, flattened, about 1/16 inch long, and grooved on each side. A single plant produces an average of nearly 15,000 seeds, which can be dispersed when the mature plant breaks off and becomes a tumbleweed. The plant is drought-tolerant, enhancing its ability to spread.
