Clustered poppy mallow is a generally erect perennial that is native to the deep South (Alabama to North Carolina) and Midwest (Missouri to Wisconsin and Indiana). In Missouri, it has been recorded in the past as growing in four counties (St. Louis, Scott, Franklin and Mississippi) in dryish, rocky or sandy soils in prairies, open woods, sandy open ground and limestone glades (Steyermark). However, it is very rare and possibly extinct in Missouri today. Stems, leaves and flower stalks are hairy. Basal leaves are triangular. Stem leaves are narrower and sometimes lobed. Plants typically grow 1-3’ tall on slender, branching stems. Five-petaled, deep rose-purple flowers (to 2” wide) bloom in clusters at the ends of long axillary stalks. Stamens and style form a prominent central column typical of mallow family members. Blooms in summer (July and August). The closely related purple poppy mallow (Callirhoe involucrata) is, by contrast, a procumbent, mat-forming plant.
No serious insect or disease problems.
