Checkerbloom Mallow Sidalcea sparsifolia is a perennial found in diverse habitats from fields to grassy hillsides at elevations from sea
level to 7,500 feet. This plant is native to California. In the Santa Monica Mountains this plant is part of the following communities:
chaparral, coastal sage scrub, or on the edge of riparian woodland. A preference for rocky soil and partial shade, this plant uses it deep
roots to colonize areas where it grows. Various sources describe the below ground part of the plant as either root, rhizome
or caudex -Santa Monica Mountains Wildflowers Guide.
If rainfall is sparse the plant may not bloom, and an additional bloom is possible if there is a late rain. After the blooms are gone,
this plant will die back to the ground. Interesting note about the blooms - they last less than a day before shriveling up. When you see
this bloom, keep that in mind and take a moment to appreciate the ephemeral beauty of flowers!
Herbaceous (stems are green and flexible) perennial grows up to 80 cm tall. Leaves: deeply lobed, with long stalks (petioles);
hirsute (hairy) below, stellate (star like) above. Flowers: in many - flowered racemes (short equal stalks along a central stem), blooms are pink
to lilac, often with white veins. I was looking thru my photos and noticed that some plants have Stamens and some do not. Milt's book says Male and Female
plants are an identifying trait and of course another book states that the flower is bisexual (having both male and female parts) and that the flower
actually aborts the stamens of the upper flowers.
Sidal'cea: a combination of two related genera in the Mallow family, Sida and Alcea, which were also two Greek names for mallow
(ref. genus Sidalcea)
