A delightful, hollyhock-like perennial rarely found outside its native Oregon, and not in every county. Stands of this perennial have been reported in Washington, Multnomah, Yamhill, Benton, Linn, Lane, Douglas, Coos and Jackson counties, but not all are documented.
Reaching a full 5,’ this plant develops stout stems to support one to five densely flowered racemes.
Rose-pink petals age to a deep purple and are indeed regal.
This checkermallow thrives in full sun to partial shade and is a riparian species, so it needs consistently moist soil in the garden.
It is considered to be rare or threatened in its natural habitat.
Butterflies find it irresistible.
