Ranunculus occidentalis, commonly known as the Western Buttercup, is a perennial herb native to a variety of habitats including moist meadows, grassy slopes, streambanks, and open forest clearings in western North America, from Alaska to central California. It is often found at elevations up to 7218 feet. This species typically grows to a height of 12-18 inches (30-45 cm) with a similar spread. The Western Buttercup has glossy, bright yellow flowers that bloom from spring to early summer, which are highly attractive to pollinators. Its foliage is usually divided into three lobed leaflets, providing a delicate texture in garden settings.

The Western Buttercup is valued for its cheerful flowers and its adaptability to different moisture conditions, although it prefers moist, well-drained soils. It is used in wildflower gardens, meadow plantings, and as a part of native plant landscapes. While it thrives in full sun to part shade, it requires regular water during the growing season to maintain its lush appearance. It is not typically associated with any serious diseases or pests, but it can be toxic to livestock if consumed in large quantities due to the presence of protoanemonin. Gardeners should also be aware that it can cause skin irritation in some people. Despite its traditional use by indigenous peoples, it is not commonly used for culinary or medicinal purposes today due to its toxicity.CC BY-SA 4.0
