Grevillea, Hakea, Isopogon (Cone Flower) & Petrophile

Silky Oaks (Grevillea spp.), Pincushion Trees (Hakea spp.), Cone Flowers (Isopogon spp.), and Petrophile are evergreen, small to medium-sized woody shrubs or medium sized trees within the silvertree family (Proteaceae) and mostly native to Australia, with several Grevillea species occuring in New Guinea, New Caledonia, Indonesia and Sulawesi. They have leathery, narrow to broad linear or elongated oval leaves and showy, bright colored terminal flower racemes. All make good pot plants in any fertile, humus rich, slightly sandy to rocky, lime-free soil in a sunny spot throughout the year with a winter minimum of some 10°C and reduced watering. Too large plants can be pruned back in spring.
Sow seeds flat in any humus rich, sandy soil at some 20°C. Cover seeds slightly with soil only. Keep pots always moist from beneath and sunny until germination starts, then keep soil drier.
All are of USDA climate zone 11.
