Cup Clover (Trifolium cyathiferum) is an annual forb or herb native to the Pacific Northwest and western states of North America, including British Columbia, California, Idaho, Montana, Nevada, Oregon, and Washington. A member of the Fabaceae family, this plant thrives in moist environments with light requirements ranging from full sun to partial shade. Cup Clover grows up to 0.5 meters tall and is known for its edible flowers and leaves, which can be used in various culinary applications, such as fresh in salads or cooked as a green vegetable. The flowers may also be added to dishes for a mild flavor. This plant is also valued for its dynamic accumulator and nitrogen-fixer properties, making it a useful addition to gardens and landscapes. Cup Clover has a documented history of medicinal use, though it is important to exercise caution and seek professional guidance before using it for any medicinal purposes. Its ability to adapt to different soil types, including light (sandy), medium, and heavy (clay) soils, further enhances its versatility in various growing conditions. Cup Clover can be propagated by sowing seeds directly into the garden bed in spring. Its distinctive features include its edible parts—flowers and leaves—and its adaptability to diverse soil types and growing conditions. This plant is both an ornamental and a valuable resource for those interested in sustainable gardening and natural remedies.
