Description and Growing Information
| General Description | In order to survive in poor soils Grevillea have evolved with proteoid roots. These roots which develop each season, grow into the top levels of the soil to extract nutrients. |
| ID Characteristic | Rigid linear leaves holding bright pink clusters of flowers |
| Landscape | Wall-side borders and flower borders. |
| Propagation | By seed or semi-hardwood cuttings |
| Cultivation | A marginally frost hardy cultivar that prefers acidic growing conditions and is intolerant of wet soils. Grevillea are particularly intolerant of phosphorous so a fertilizer low in this nutrient is a must. |
| Pests | No major issues. |
| Habitat | Members of the Grevillea genus are found only in the southern hemisphere. |
