Extremely hardy and adaptable, it thrives in SA's full range of conditions from coastal gardens to the Adelaide Hills, providing reliable winter-to-spring colour, year-round structure and outstanding bird-attracting value. The full-size species is larger and more vigorous than the Nana form, making it ideal for screens, windbreaks and mixed native borders.\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 1.5–2.5 m H x 1.5–2.5 m W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrowth Rate:\u003c\/strong\u003e Moderate to fast; 25–45 cm per year; dense, bushy and spreading with a naturally rounded informal habit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFoliage:\u003c\/strong\u003e Narrow, needle-like, dark-green leaves resembling rosemary; prickly tips; fine, dense texture year-round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlowers:\u003c\/strong\u003e Red and cream spider-type flowers; prolific display winter–spring with lighter repeat flushes; non-fragrant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeasonal Interest:\u003c\/strong\u003e Near year-round flowering; peak winter–spring; dense foliage provides year-round structure and screening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWildlife Value:\u003c\/strong\u003e Outstanding honeyeater and bird attractant; dense foliage provides year-round nesting and shelter for small birds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance:\u003c\/strong\u003e Drought-tolerant once established; frost hardy (to −5°C); heat-tolerant; wind-tolerant; coastal-tolerant (second-line); clay-tolerant if free-draining\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlanting Density:\u003c\/strong\u003e Screen\/informal hedge: 1–1.5 m apart; mixed border: 1.2–1.5 m apart; specimen: 2–2.5 m clearance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePet Friendly:\u003c\/strong\u003e May cause contact dermatitis in sensitive pets; mild tummy upset if ingested in large quantities — discourage chewing\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 to part shade; flowers best in full sun\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSoil:\u003c\/strong\u003e Well-drained loam, sandy loam or clay loam; avoid phosphorus-rich fertilisers and waterlogging; tolerates slightly alkaline soils\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Needs:\u003c\/strong\u003e Establishment: 2 deep soaks\/week for 8–12 weeks.
