Trifolium ciliolatum, commonly known as foothill clover, is an annual herb native to grasslands, meadows, and open woodlands of western North America, ranging from Washington to Baja California. It often occupies disturbed sites, which can include areas affected by grazing or fire. Foothill clover typically grows erect with a height of up to 60 centimeters. Its stems are hairless, and the foliage consists of toothed oval leaflets with bristle-tipped stipules. The inflorescence is a dense head of small, pea-like flowers that are pinkish or purplish in color, which can be quite showy when in full bloom during the spring and early summer months.

The plant is valued for its ability to fix nitrogen in the soil, improving soil fertility, and is sometimes used in restoration projects. It is also appreciated for its ornamental flowers and can be used in wildflower meadows or as part of a native plant garden. Foothill clover is drought-tolerant and prefers full sun to partial shade, thriving in well-drained soils. While it is not typically grown for culinary purposes, Native American groups have historically consumed the seeds and vegetation. It is generally free from major pests and diseases, but can be outcompeted by more aggressive plants if not managed.CC BY-SA 4.0
