Rocky Mountain parnassia is a delicate alpine wildflower that thrives in cool, moist, partially shaded environments mimicking its native mountain streamside habitat. It requires consistently moist, well-drained soil rich in organic matter and does not tolerate heat or drought. This plant is best suited for experienced gardeners creating native or alpine rock gardens in cooler climates.
