Checker Bloom, Miniature Hollyhock, False Mallow, California Checkerbloom, Checker Mallow, Dwarf Checkerbloom, Wild Hollyhock


Spectacular when in full bloom, Sidalcea malviflora (Checker Bloom) is a perennial wildflower boasting spikes of 2-inch-wide flowers in shades from pale pink to bright rosy purple. The flowers open in the morning and twist closed at night. Blooming in mid-late summer for well over a month, they are reminiscent of Hollyhocks, but do not have their dominating height or aggressive self-seeding. Attractive to butterflies, bees and hummingbirds, the blossoms are borne along erect stems above dense tufts of dark-green, palmately lobed, fleshy leaves. Excellent cut flowers. Great for cottage gardens.

  • Grows up to 2-4 feet tall (60-120 cm) and 12-18 in. wide (30-45 cm). May require staking. This plant reseeds readily.
  • Thrives in well-drained soils in full sun. This plant tolerates a wide variety of soils, and prefers damp winter conditions and dry summer conditions.
  • Virtually disease free. Keep an eye out for Japanese beetles.
  • Remove spent flower stalks for rebloom and to encourage basal overwintering foliage.
  • Propagate by seed. Soak in warm water 6 hrs.
  • Native to Oregon, California, Baja California.
