原生地・分布（英語）:

説明（英語）: Genus of about 20 species of evergreen perennials or subshrubs from screes and open rocky places at high and low altitudes in New Zealand. They form mats or cushions of dense, overlapping, linear to diamond- or spoon-shaped, silvery leaves. The usually small, disc-shaped flowerheads are borne singly or in few-flowered, terminal clusters. They thrive in regions with cool summers and mild winters, and are excellent foliage plants for a rock garden, raised bed or scree bed, or for an alpine house.

耐寒性（英語）: Hardy to about - 10°C (14°F) in well-drained soil.
