Party girl prairie mallow is an upright perennial flower with medium green, shiny leaves. Its best attribute is the upright stalks of flowers that appear in late summer.
The flowers are funnel-shaped and resemble a hollyhock. Since they are bright pink with a white eye, the blossoms add a lot of color to the landscape. It grows best with regular moisture.
Party girl prairie mallow grows in the moderate water zone at the Xeriscape Demonstration Garden. The flowers are very nice. The only drawback to this plant is the abundant number of seedlings it produces. It also spreads by underground runners, and will become a large patch over time.
Remove old growth to the ground in late winter. To reduce the number of volunteer seedlings, remove the spent flowers promptly after they have finished blooming.
If the stems begin to look unattractive after it has finished blooming, cut to ground level. New leaves will grow and the plant will look better for the rest of the growing season.
