Cultivation

edit

Rocky Mountain mariposa is valued by gardeners in the American prairies and intermountain west for the elegance of its deeply cupped flowers with their recurved edges. Though they will successfully bloom and propagate outside their native range, they are closely adapted to the dry conditions of the plains and western mountains. Gardeners in wet climates must take careful precautions against excessive moisture in all seasons, but particularly during the winter. Often a deep layer of gravel 10–15 cm deep will be placed around 6 cm under the bulbs for extra drainage. They require a well draining, but not sandy, fine textured soil without much organic matter. Bulbs are planted 10 cm deep. In a favorable climate they will live as much as 30 years.[3]
