Sidalcea is most commonly known as Prairie Mallow or Checkerbloom. Other names include Checker Mallow, Wild Hollyhock, and Oregon Checker-mallow depending on the species. The "checker" names refer to the patterned veining visible in the flowers of some species.
Sidalcea produces tall, slender stems bearing racemes of silky, five-petaled flowers that closely resemble miniature hollyhocks. The flowers come in shades of pink, rose, lilac, and white, with distinctively notched or fringed petal tips, and bloom from the base of the spike upward through summer.
Sidalcea symbolizes grace, elegance, and natural feminine beauty. Its refined hollyhock-like flowers on slender stems evoke the gentle, airy character of wild meadow flowers, making it a symbol of effortless elegance in both garden and natural landscapes.
Grow Sidalcea in full sun to partial shade in moderately fertile, well-drained soil with regular moisture. Deadhead spent spikes promptly to encourage reblooming into late summer or fall. Divide clumps every 2–3 years to keep plants vigorous. Taller varieties may benefit from staking.
Sidalcea and Hollyhock (Alcea) are related — both belong to the Mallow family (Malvaceae) — but they are different plants. Sidalcea is a more refined, slender perennial with smaller, more delicately fringed flowers, while Hollyhock is taller and coarser with larger blooms. Sidalcea is also more reliably perennial in garden conditions.
Yes, Sidalcea is an excellent pollinator plant. It attracts bumblebees, butterflies, and specialist native bees — including checkered-skipper butterflies whose caterpillars use mallow-family plants as host plants. It is a valuable addition to any wildlife-friendly garden.
