Unusual tree/shrub from alpine areas of Australia into Tasmania with spiky modified phyllodes as leaves. The spiky leaves are blue green and it forms an airy conifer like large plant very quickly. In spring flossy white flowers crowd the blue green leaf axils and are showy for several weeks. Full sun and average to poor well drained soil. Little summer water once established. Fast growing in youth to its ultimate size. Cold hardy for us to 5ºF but avoid exposure to subfreezing winds. Proteaceous- do not fertilize or even add compost. Un amended native soils are ideal. To 9′ tall and 6′ wide in 6 years. Great on slopes. Casts no shade- great textural element year round. High deer resistance. Very unusual plant- out of the ordinary and cool. Pronounced HAY-kee-uh.
