It forms a neat, dome shaped mound of narrow foliage in a glowing shade of yellow, lit by lime tinted new growth in spring and warm copper tips when the weather turns cold. Over a long spring to summer season it is topped with airy heads of zesty lime-green flowers, each with a tiny red eye, giving months of colour on a plant that rarely climbs above knee height.\u003c\/p\u003e\u003cp\u003eBred in the UK and released in 2025, this is a genuinely hardy exotic. Rated \u003cstrong\u003eRHS H5\u003c\/strong\u003e, it shrugs off hard frost once established and keeps its golden foliage right through winter, so there is no bare season to wait out. It is also impressively drought tolerant, thriving on poor, gritty soils and in hot, dry corners where thirstier plants struggle.
