- Alpine: needs sharp drainage (scree, gravel or a rock-garden pocket) and resents winter wet more than cold.
- Leathery leaves with a silvery felted underside; needs cool, moist summers and acid soil (the New Zealand bed of the rock garden).
- Flowers in December–January in New Zealand; date here is the northern equivalent.
