Ranunculus triternatus is a delicate native buttercup found in moist meadows and streambanks of the Pacific Northwest United States. It thrives in partial shade with consistently moist soil and goes dormant in drier summer conditions, so avoid overwatering once foliage dies back. Best suited to naturalistic or native plant gardens in the Pacific Northwest, it is rarely available commercially and most often sourced through native plant societies.
