[Wikipedia] Growth Requirements: Although the shrub tends to grow in areas where there is a lot of accumulation of snow, adequate rain precipitation is needed for the continued growth of Cassiope Mertensiana. The shrub must be exposed to enough sunlight and warmer conditions for proper growth during the growing season. (link added by Mary Ann Machi)
