Queen Anne's lace (Daucus carota) gets its name from the round clusters of tiny white flowers that form atop its tall stalks. The biennial herb, also known as "wild carrot," has a six-month blooming period.
Queen Anne's lace blooms from May through October, according to North Carolina State University. Because Queen Anne's Lace is a biennial, its life cycle is two years, with flowers appearing during the second year, according to Fairfax County Public Schools.
The plant's tiny flowers grow in 3- to 4-inch-wide, flat clusters. Each flower produces two seeds, which it releases from mid-summer through mid-winter, according to North Carolina State University. Queen Anne's lace stalks can reach 1 to 4 feet tall.
Queen Anne's Lace can crowd out native species. In Ohio, Iowa, Michigan and Washington, it is classified as a noxious weed, according the U.S. Department of Agriculture.
Queen Anne's Lace produces an edible root that is a type of carrot, according to Fairfax County Public Schools.
