Sidalcea is a genus (approx. 25 species) of the botanical family Malvaceae. It contains several species of flowering plants known generally as checkerblooms or checkermallows, or prairie mallows in the United Kingdom. They can be annuals or perennials, some rhizomatous. They are native to West and Central North America.

In mid- to late summer the clumps of toothed basal leaves produce erect flowering stems, with 5-petalled mallow-type flowers in terminal racemes, in shades of pink, white and purple.

Sidalcea sparsifoliais native to the West Coast of the United States, from Washington to California, and into northwestern Baja California. It is a common plant of chaparral, coastal sage scrub, and other habitat types.

Sidalcea sparsifoliaisis somewhat variable in appearance and there are many subspecies. In general, it is a perennial herb growing from a woody caudex and rhizome, its stem reaching about 60 centimeters in maximum height. It is sparsely to densely hairy in texture. The leaf blades are variable in shape but are often divided deeply into several lobes. The inflorescence is a dense or loose array of several flowers. The flower has five petals in shades of bright to dark pink, often with white veining, and measuring one to over three centimeters in length.
