The cream of the the New Zealand woody Asters and a star in the rock garden.  This comes from the alpine areas of the mountains near Marlborough up to 1900 meters.  Flowers are a bit of yellow teminal nothings but the whipcord silvery branchlets are exquisite perfection.  Full sun and drier lean soil will suit this.  Took 3 nights of 0F at Hedgerows Nursery in 2009.
