This compact, dense cultivar forms a rounded shrub with fine, deeply-divided grey-green foliage that provides excellent textural contrast in the garden. The masses of vibrant golden flower clusters create a brilliant display while attracting honeyeaters and native bees. Drought-tolerant once established, exceptionally long-flowering, and highly ornamental, it thrives in Adelaide's conditions while providing reliable colour and wildlife habitat with minimal care. Ideal as a feature shrub, informal hedge, bird-attracting garden centrepiece, or mass-planted for impact, 'Old Gold' brings reliable golden brilliance and year-round interest to South Australian landscapes.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eMature Size:\u003c\/strong\u003e 2.0–2.5 m H × 2.0–2.5 m W (compact rounded shrub);
