Oregon checker mallow is a graceful native perennial suited to partly shaded borders and meadow gardens across the Pacific Northwest. It requires little care once established and rewards gardeners with tall spikes of rose-pink flowers throughout summer. Regular deadheading can extend the blooming season and keep the plant looking tidy.
