Plant Description and Details

Tall spikes of light rose to deep pink bloom in early summer. Occuring on moister sites across the western U.S., our native hollyhock is both decorative and vigorous. After the flower display is gone, rich maple-shaped leaves remain to give texture andstructure to the garden, turning to a golden hue as fall comes on. Under optimum conditions of fertile soil and high moisture, it can become quite large. Try it as a backdrop, as a specimen plant, or in moist meadow plantings.
