Arctic White Heather is a delicate, mat-forming evergreen shrub native to arctic and subarctic regions, producing nodding white bell-shaped flowers in summer. It requires cool temperatures, high humidity, acidic well-drained soil, and is very difficult to cultivate outside of rock gardens or alpine environments. This specialist plant is best suited for dedicated alpine or peat garden enthusiasts with experience growing ericaceous shrubs.
