A good choice for the partially shaded scree garden, wall or alpine trough. It forms a low evergreen cushion or mound of bright green leaves, bearing short stems of upfacing, cup-shaped white flowers in spring. Requires a cool, moist location. Dislikes drought and hot humid summer weather. Shear lightly after blooming to remove the flower stems and encourage compact new growth. Adapts well to growing in clay pots or alpine troughs. A light top-dressing of sand right after flowering will help to keep the clumps tight and free from root-rot. Do not prune back in autumn or spring.
