Sidalcea oregana, commonly known as Oregon checkerbloom, is a perennial herb native to the Pacific Northwest, including regions from British Columbia to California and eastward to Utah. It is typically found in moist meadows, wetlands, and along streambanks, where it contributes to the biodiversity of these ecosystems. The plant can reach over one meter in height, emerging from a woody taproot, with most leaves concentrated at the base of the stem. The leaves are rounded with toothed margins. From late spring to midsummer, it produces a spikelike raceme of showy pink flowers, each with five petals up to 1 inch long, attracting pollinators such as bees and butterflies.

Oregon checkerbloom is valued for its ornamental qualities, particularly its vibrant pink blooms that add a splash of color to garden settings. It is often used in native plant gardens, restoration projects, and as a border plant in moist garden areas. This species prefers full sun to part shade and requires moist, well-drained soil to thrive. While it is relatively low-maintenance, it may benefit from occasional watering during dry periods. Gardeners should be aware that in optimal conditions, Sidalcea oregana can spread readily, potentially becoming aggressive in garden settings. It is also susceptible to rust and other fungal diseases, especially in humid climates.CC BY-SA 4.0
