Facts About

Whorled mallow is a Eurasian species, cultivated in Asia for its edible leaves, and elsewhere as an ornamental. Its North American distribution may be flawed due to misidentification, but it is found in all New England states.

7.  Malva verticillata L. E

whorled mallow. Malva crispa (L.) L.; M. verticillata L. var. crispa L. • CT, MA, ME, NH, RI, VT. Fields, roadsides, waste areas. The mature mericarps of Malva verticillata have lateral veins that are prolonged into small teeth along the margin of the mericarp, but there is no continuous marginal wing. The calyx is accrescent in this species (similar to M. parviflora). More work 
is needed to confirm the distribution of this species. Some records may actually refer to 
 M. parviflora or M. rotundifolia.
