Herbwilliam
Mock Bishopsweed
Florida native
A common herb mainly of swamps, pond margins and wet ditches throughout nearly all of Florida. The range extends throughout the southeastern United States, west mainly into Texas to Kansas, north to Missouri and Kentucky, and northeast to New York and Massachusetts.
This delicate little wildflower grows from 30-46cm (12 to 18 in.) tall. Tiny white flowers are arranged in compound umbels with a whorl of threadlike bracts extending from the base of the umbel. The compound leaves are made up of finely dissected linear leaflets.
Ptilimnium capillaceum is the only species of this genus in Florida. Like some other members of the carrot family, mock bishopsweed is a larval host for black swallowtail butterflies.
Ptilimnium capillaceum is a member of the Apiaceae - Carrot family.
