- My friend Hope once said, "Queen Anne's Lace is to the carrot as Asian jungle fowl is to the chicken." Indeed,
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
has pink, rose, or purplish flowers. Form
(pictured above) has white flowers with the central most flower of the umbel being dark purple. Form
has all white flowers, none purple, as the name suggests.
