It has narrow coarse toothed leaves. The entry above states multiple USDA zones, it would most probably be best planted in USDA Zone 9 only and zone 11 would most probably stress the plant. Showy silvery-red/pink flowers (hence the common name Raspberry Frost) with golden styles in spring. The plant is so pretty it is often used in dried floral arrangements. Will require well drained light to medium soil with added lime. Steer clear of using any type of a phosphorous fertilizer with any Banksias.
Propagation is virtually the same as the Banksia spinulosa var. collina. Excerpt from a previous entry of mine on propagation-
“Propagation from seed or cuttings is basically easy. Named cultivars should only be propagated from cuttings as they will not come true from seed. The fruits protect seeds from animals that forage. Most of the time, the fruits will not open until they have been burnt or are thoroughly dried out. The best way to prepare the seed would be to put it in your oven at about 130F for an hour or so. The follicles will open and you will be able to get at the seed. There will be two black seeds in each follicle with a separator. The seeds are prone to fungal attacks therefore any medium should be baked in your oven or sterilized in your microwave prior to use. Transplant seedlings to small pots as soon as the first true leaves appear. A combination of peat moss and sand can be used. Although the plant may be somewhat drought tolerant when mature, at no time should seeds be allowed to dry out.” Seed should germinate in about 3-12 weeks at 65-80F.
