How to Identify
A perennial buttercup reaching 0.6 m (2 ft) tall with hermaphrodite flowers blooming May to July. Tolerates light sandy, medium loamy, and heavy clay soils across mildly acidic to basic pH ranges. Grows in semi-shade or full sun and prefers consistently moist conditions.
How to Grow
We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it should succeed outdoors at least in the milder areas of the country. The following notes are based on the general needs of the genus. Prefers a moist loamy soil. A greedy plant, inhibiting the growth of nearby plants, especially legumes.
Propagation: Sow seed in spring in a cold frame. Prick seedlings out into individual pots once large enough to handle, and plant out during summer. Larger divisions can be planted directly into permanent positions. Smaller divisions are better potted up and grown on in light shade in a cold frame until well established, then planted out in late spring or early summer.

Source ↗Ranunculus occidentalis, the western buttercup, is a species of buttercup found in the western regions of North America. Its distribution extends from Alaska through British Columbia and Alberta to central California. The flower can be seen in open meadows, forests, and other generally flat areas up to an elevation of 2,200 metres (7,200 ft). Aleut first nations may have used juice from the plant as a poison, its toxicity arising from the substance protoanemonin. Shasta first nations coincided blooming Ranunculus occidentalis with salmon runs in the summer. The seeds were used to make pinole, a staple food. This plant is similar to, and sometimes difficult to distinguish from, the California buttercup (Ranunculus californicus).
