Scouler's monkeyflower is a Pacific Northwest native perennial that thrives in moist, part-shade conditions, making it ideal for streamside gardens, rain gardens, or consistently irrigated borders. Plant in rich, moisture-retentive soil and ensure regular watering to mimic its natural riparian habitat.
