Trifolium albopurpureum, commonly known as rancheria clover, is an annual herb native to the west coast of North America, specifically found in open woodlands, grasslands, and montane regions from British Columbia to Baja California. It exhibits a decumbent or erect growth habit, reaching up to 1 inch in height, with trifoliate leaves that are characteristic of the clover genus. The inflorescences are dense, spike-like clusters of flowers, each with a purple and white corolla nestled within a hairy calyx, blooming from late spring to early summer. The flowers are modest in size but can add a subtle charm to wildflower gardens and meadows.

Rancheria clover is valued for its nitrogen-fixing abilities, which improve soil fertility, making it a beneficial addition to restoration projects and naturalized plantings. It is also used as a forage plant for livestock and wildlife. This species prefers full sun to partial shade and tolerates a range of soil types, provided they are well-drained. It is relatively low-maintenance, requiring minimal water once established, and is generally free from serious pests and diseases. However, it can be susceptible to root rot in poorly drained soils. Rancheria clover is not commonly available in the horticultural trade but can be grown from seed by those interested in native plant gardening or habitat restoration.CC BY-SA 4.0
