Why We Love It:
This rare form of Snow-in-Summer is grown just as much for its striking silver foliage as for its blooms. The dense, silvery mats create beautiful contrast against stone, gravel, and darker green plants, bringing brightness and texture to sunny gardens year-round. Unlike more aggressive forms, it stays compact and controlled, making it especially useful for containers, edging, raised beds, and spilling gently over walls without overwhelming nearby plants.

Additional Info:
Rare and collectible with excellent drought tolerance once established. Performs best in lean, sharply drained soils and should not be planted in heavy or poorly drained clay. Easily trimmed to shape or control spread if needed. Fire resistant and highly adaptable to hot, sunny sites with minimal irrigation.
