Acmispon americanus, commonly known as American bird’s-foot trefoil or Spanish clover, is an annual herb native to a variety of habitats including grasslands, open woodlands, and chaparral regions across California, the Western United States, Western Canada, and northern Mexico. It typically grows up to 10 inches tall and has a hairy, upright form. This species produces clusters of pale pink to cream flowers from late spring to early summer, which are attractive to pollinators such as bees. The foliage is fine-textured, adding a delicate appearance to the plant.

American bird’s-foot trefoil is valued for its drought tolerance and ability to thrive in poor, well-drained soils, making it suitable for xeriscaping and restoration projects. It is also used in wildflower mixes for meadows and naturalized areas. In cultivation, it requires minimal maintenance, thriving in full sun and tolerating a range of soil types, provided they are well-drained. While not commonly used in formal garden settings, its resilience and adaptability can make it a useful plant for erosion control on slopes and disturbed sites.CC BY-SA 4.0
