Annual grass refers to grass species that complete their entire life cycle—germination, growth, flowering, and seed production—within one year. These grasses typically germinate in the spring, grow rapidly, and die off by the end of the growing season, often leaving seeds to germinate in the following year. Common examples include species like crabgrass and foxtail. Annual grasses are often used in agriculture and landscaping for quick cover and soil stabilization.
