Exceptionally well-suited to Adelaide and South Australia, it thrives in heat, dry soils, coastal winds and poor, low-fertility sites. Its dense matting habit suppresses weeds, stabilises banks and spills attractively over retaining walls. New growth often emerges bronze-red, adding seasonal interest. While not fragrant, the foliage carries a subtle resinous native aroma when handled.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMature Size:\u003c\/strong\u003e 0.3–0.5 m H × 3–6 m W – vigorous, prostrate, wide-spreading groundcover\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrowth Rate:\u003c\/strong\u003e 30-60 cm of outward growth per year under good conditions\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFoliage:\u003c\/strong\u003e Glossy dark green leaves with bronze or coppery new growth in cool weather or early spring; dense, cascading habit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlowers:\u003c\/strong\u003e Abundant red toothbrush-style blooms from late winter through spring, with spot flowering in autumn\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeasonal Interest:\u003c\/strong\u003e Lush evergreen foliage year-round; colourful new growth; dramatic flowering peak in late winter–spring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWildlife Value:\u003c\/strong\u003e Highly attractive to honeyeaters, native bees and other pollinators; dense cover offers habitat for small ground fauna\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance:\u003c\/strong\u003e Excellent drought, heat and wind tolerance; handles coastal exposure (second-line, sometimes first-line with drainage); light frost hardy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlanting Density:\u003c\/strong\u003e Mass coverage: 1 plant per 3–4 m²; spillover edges: 1 per 2–3 m; bank stabilisation: 1 per 2–4 m²\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePet Friendly:\u003c\/strong\u003e Generally safe, though grevillea foliage can irritate sensitive skin—discourage chewing or contact for sensitive pets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eWhere It Works Best\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSunlight:\u003c\/strong\u003e Full sun for best flowering and density; tolerates light part shade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSoil:\u003c\/strong\u003e Free-draining sandy loam, gravelly soils or improved clay; avoid waterlogging; always use low-phosphorus native fertiliser\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Needs:\u003c\/strong\u003e Establishment: 2 deep soaks\/week for 8–12 weeks.
