Other info. - This species can be found in the southern half of Missouri. The plant is easy to ID in the field because of its habitat, finely divided leaves, and big, all-yellow flowers.
There are two varieties of the plant in Missouri. Variety harveyana (Gray) Scherff can be found in the southeastern portion of the state. This variety has very finely divided leaves with filiform segments no more than 1.5mm broad. Variety grandiflora has leaf segments which range from 1-5mm broad. This variety is found in the southwestern portion of Missouri and also in a few scattered locations along the Missouri river.
C. grandiflora is a showy species which does well in cultivation.
