“Grevillea alpina commonly known as Mountain Grevillea, Cat’s Claw or Alpine Grevillea belongs to the Proteaceae family. Despite its name this species is not restricted to alpine areas and is rarely found there.
Flowers are typically 1-3.5 cm long, can be a single colour, cream, green, yellow, orange, pink or dull red, or it can be a combination of these colours.
Grevillea alpina can be propagated both vegetatively and from seed. Cuttings should be taken from interseasonal growth (semi-hard material) flowering material should be avoided. A length between 5-10 cm should be used with half to a third of the leaves stripped off. A gel type plant hormone should be used. Cuttings are slow to grow, taking 6–8 weeks to strike.
Seed is the preferred method of propagation. Plants grown from seed have a stronger root system and also have a nicer growing shape, needing less pruning. For best results use fresh seed from the form that grows closest to your area. The seeds have an inhibitor that prevents germination immediately and this cannot be overcome by using treatments such as nicking, smoke water or peeling. Seeds should be soaked in room temperature water for 24 hours before sowing. Both cuttings and seeds should be sown in a coarse perlite mixture. The mixture needs to be well drained or basal rot can occur. Bottom heat should be used especially in the colder months.
This species is sensitive to excess water and excess nutrients. The watering regime differs after planting depending on the soil types; soils with better drainage can have more water. Watering should be reduced in summer, as the plant likes dry summers. Don’t use fertiliser in pots or in the garden, as this species is adapted to poorer soils.
When conditions are right this species can live for a long time, and with regular pruning will maintain a nice shape. Flowers are produced from July through to May if conditions are favourable. Flowers on all forms attract honey-eating birds. Grevillea alpina grows best in areas that have a dry summer, as it dislikes humidity. With the variability in both form and flower colours of Grevillea alpina, this species is a desirable horticultural plant.”
