Ranunculus alismifolius var. alismellus is a rare western North American native buttercup found in moist mountain meadows and streambanks. It requires consistently moist, humus-rich soil and cool temperatures to thrive, making it challenging to cultivate outside its native alpine and subalpine habitats. Best suited for naturalistic bog or streamside plantings in cooler climates.
