{"product_id":"leucanthemum-wirral-supreme-2-litre-pot","title":"Leucanthemum Wirral Supreme 2 Litre Pot","description":"\u003cp\u003eLeucanthemum × superbum 'Wirral Supreme' is a classic garden perennial beloved for its bold, pure-white double flowers and long, reliable blooming season. A refined selection of the popular Shasta daisy, 'Wirral Supreme' produces large, fully double flowerheads with an anemone-like centre of tightly packed white petals surrounded by a neat ray of broader outer petals — an altogether more luxurious look than the single-flowered forms. Held on strong, upright stems above a clump of dark green, toothed foliage, the flowers make an outstanding display in the garden and are equally superb as long-lasting cut flowers. This is a robust, clump-forming perennial that returns reliably year after year, making it a staple of cottage gardens, herbaceous borders and pollinator-friendly planting schemes alike.\u003c\/p\u003e\n\n\u003ch2\u003eGrowing conditions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eAspect and position.\u003c\/strong\u003e 'Wirral Supreme' thrives in a position that receives full sun for the majority of the day. It will tolerate light, dappled shade but flowering is most prolific and stems remain strongest in an open, sunny site. It is an excellent choice for the middle of a mixed or herbaceous border, where its upright habit provides structure and height without overwhelming neighbouring plants.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSoil.\u003c\/strong\u003e Plant in fertile, well-drained soil for the best results. Shasta daisies are adaptable to a wide range of soil types, including loam, sandy loam and clay, provided drainage is adequate — they are intolerant of prolonged waterlogging, particularly over winter. Incorporating organic matter such as garden compost at planting time will improve both soil structure and fertility. Moderately moist conditions during the growing season are ideal.\u003c\/p\u003e\n\n\u003ch2\u003eCare\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eWatering.\u003c\/strong\u003e Water regularly during dry spells, especially in the first season after planting while the plant is establishing. Once settled, 'Wirral Supreme' is reasonably drought tolerant, though consistent moisture during the flowering period will help to prolong and improve the display. Avoid watering directly over the foliage and flowers where possible to reduce the risk of fungal issues.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeeding.\u003c\/strong\u003e Apply a balanced granular fertiliser in spring as new growth emerges to encourage strong stems and generous flowering. An additional liquid feed with a potassium-rich fertiliser in early summer can further support flower production. Avoid over-feeding with high-nitrogen fertilisers, which tend to promote leafy growth at the expense of flowers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDeadheading and pruning.\u003c\/strong\u003e Deadhead spent flowerheads regularly throughout the blooming season to encourage a succession of new blooms and to keep the plant looking tidy. Cutting stems back to just above a side shoot or bud can stimulate a second flush of flowers later in the season. Once flowering has finished and the first frosts have blackened the foliage, cut the plant back to near ground level and tidy away the old stems. In milder climates, the basal rosette of foliage may persist through winter.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDividing and rejuvenating.\u003c\/strong\u003e Clumps of 'Wirral Supreme' benefit from being lifted and divided every two to three years, ideally in spring or early autumn. This practice prevents the centre of the clump from becoming woody and unproductive, rejuvenates flowering vigour and provides new plants for expanding the display or sharing. Replant only the healthy, outer portions of the divided clump and discard the congested central section.\u003c\/p\u003e\n\n\u003ch2\u003eGarden use and companions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eDesign uses.\u003c\/strong\u003e The crisp white flowers of 'Wirral Supreme' are wonderfully versatile in the garden, combining effortlessly with almost every other colour. They look particularly striking alongside bold purples and blues such as Salvia, Agastache and Veronicastrum, and pair beautifully with warm yellows and oranges from Rudbeckia, Helenium and Achillea in late-summer schemes. They are equally at home in a classic white-and-green planting alongside ornamental grasses. The flowers are also superb for cutting, lasting well in a vase with minimal preparation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWildlife value.\u003c\/strong\u003e Although the double flowerheads offer somewhat less nectar than single-flowered forms, 'Wirral Supreme' still attracts a range of beneficial insects, including bees and hoverflies, and the seed heads that follow can provide a modest source of food for birds in autumn and winter.\u003c\/p\u003e","brand":"Grasslands Nursery","offers":[{"title":"Default Title","offer_id":57105994678598,"sku":"173058","price":4.35,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/7948\/8326\/files\/Leucanthemum-Wirral-Supreme-2-Litre-Pot_173058_2026-08-11.jpg?v=1786442773","url":"https:\/\/www.grasslands.co.uk\/products\/leucanthemum-wirral-supreme-2-litre-pot","provider":"Grasslands Nursery","version":"1.0","type":"link"}
