Other info. - My friend Hope once said, "Queen Anne's Lace is to the carrot as Asian jungle fowl is to the chicken."  Indeed, Daucus carota is the wild form of the cultivated carrot. It is also a serious weed in Missouri. As the compound umbel matures it folds in on itself trapping all the spined fruits until some animal brushes the plant and is covered with the seeds.
Steyermark lists three forms of the plant. Form roseus has pink, rose, or purplish flowers. Form carota (pictured above) has white flowers with the central most flower of the umbel being dark purple. Form epurpuratus has all white flowers, none purple, as the name suggests.
