Wild carrot, or Queen Anne's lace, is a biennial. During the first year, lacy fern-like leaves develop in a basal rosette form. The leaves are compound with multiple leaflets. Wild carrot has a slender woody taproot. The flowers of wild carrot are small and white. The center flower in the clusters is first to bloom and is usually purple. The flower forms in flat umbrella shaped clusters, 3- to 6-inches in diameter, called umbels. The hollow flower stalks develop in the second year, and stand 2- to 4-feet high. Wild carrot reproduces by seed. Wild carrot is found in the eastern half of the United States, from southern Canada to Northern Florida.
Wild carrot cannot compete in a cultivated turfgrass stand. It is usually found in low-maintenance or abandoned areas. It is usually found on well drained to dry soils. Proper mowing will prevent the establishment and production of the seedhead in the spring.
Make your post-emergence herbicide application to wild carrot that is actively growing and in the rosette to flower stage of growth.
