IPM1007, Revised November 2009
A biennial that is closely related to garden carrots, but with a much reduced taproot. During the second year of growth, the plants produce stalks with white, flat-topped flowers. A solitary purple flower often occurs in the center of the cluster of white flowers and these flower clusters often curve inward at maturity producing a "bird's nest." Cotyledons of emerging seedlings are linear to the extent that they are often mistaken for a grass seedling. Leaves have long petioles, are without hairs on the upper surface, and may have hairs on the veins and margins of the lower surface. Leaves on the flowering stems are alternate, oblong in outline, with lobed segments.
