Notes
Wild hollyhock (Iliamna rivularis) is a perennial for low maintenance beds, woodland edges, and meadows. It is hardy to USDA zone 3, or down to -40°F (-40°C). This plant likes full sun to part shade and average to moist soil of most types. Pink, rose-purple, or nearly white flowers open from early to late summer on an erect spike. The large leaves are broadly heart-shaped, and plants usually reach 1 1/2 to 3 feet in drier spots.
Pairs well with Spotted beebalm, Common harebell, and Switchgrass.
