{"product_id":"summerific-holy-grail-rose-mallow","title":"Summerific® 'Holy Grail' Rose Mallow (Hibiscus hybrid)","description":"\u003cp\u003eIntroducing Summerific® 'Holy Grail' – a true garden treasure that combines stunning beauty with striking contrasts. This incredible plant boasts deep, near-black foliage with oval-shaped leaves that exude elegance and drama. The rich, deep red flowers, reaching an impressive 8-9\" across, perfectly complement the dark leaves, creating a captivating visual harmony. As a bonus, once the blooms fade, the bright green calyxes stand out against the dark foliage, adding even more dimension and interest to your garden. A North American native, 'Holy Grail' brings massive, tropical-looking flowers to gardens as far north as zone 4. Though it emerges a little later in spring than other perennials, its fast-growing nature ensures it quickly establishes itself, with up to an inch of new growth a day. Perfect for areas with consistent moisture, use this striking hibiscus as a focal point to build your garden around and enjoy its beauty well into the fall.\u003c\/p\u003e\r\n\u003cul\u003e\r\n\u003cli\u003e48-54 inches tall and 54-60 inches wide at maturity\u003c\/li\u003e\r\n\u003cli\u003eHardy in zones 4-9, be sure to check your USDA zone to ensure success\u003c\/li\u003e\r\n\u003cli\u003ePlant in part to full sun (4+ hours daily)\u003c\/li\u003e\r\n\u003cli\u003eSpace plants 54-60 inches apart for best results\u003c\/li\u003e\r\n\u003cli\u003eProduces deep red flowers from midsummer to fall\u003c\/li\u003e\r\n\u003cli\u003eMaintains near black foliage from late spring to frost\u003c\/li\u003e\r\n\u003cli\u003eGreat for borders, landscapes and focal point\u003c\/li\u003e\r\n\u003cli\u003eAttracts butterflies and bees while resisting deer\u003c\/li\u003e\r\n\u003cli\u003eBog plant, fall interest, long blooming, native to North America\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003cp\u003e\u003cstrong\u003eCare:\u003c\/strong\u003e \u003cspan data-mce-fragment=\"1\"\u003eHibiscus love the sun and need moist, well-drained soil. Keeping these plants watered will result in larger flowers and lush foliage. Deadheading will improve the appearance of the plant, but is not necessary for continued bloom. It is best to plant Hibiscus in the garden before the heat of the summer arrives, and should be heavily mulched the first winter. In spring, cut back any remaining stems before new growth appears. Do not trim back in fall. A strong pair of loppers or a saw will be necessary to cut this plant back. Be advised that Hibiscus is always one of the last perennials to emerge in spring. Be patient, even if you think it is dead, it most likely isn't. Its vigorous growth rate more than makes up for this late start, however. Japanese beetles find these plants especially delicious. \u003c\/span\u003eFertilize with \u003ca href=\"https:\/\/provenwinnersendlessaisle.com\/products\/zzftmr101zf01\"\u003eProven Winners® Continuous Release Plant Food\u003c\/a\u003e in spring and midsummer.\u003c\/p\u003e\r\n\u003ch3\u003eShipping Info:\u003c\/h3\u003e\r\n\u003cul\u003e\r\n\u003cli data-leveltext=\"\" data-font=\"Symbol\" data-listid=\"2\" data-aria-posinset=\"2\" data-aria-level=\"1\"\u003eEnjoy free shipping on orders over $125\u003c\/li\u003e\r\n\u003cli data-leveltext=\"\" data-font=\"Symbol\" data-listid=\"2\" data-aria-posinset=\"2\" data-aria-level=\"1\"\u003e\n\u003cspan class=\"cf0\"\u003eSize at shipping varies by the season and plant\u003c\/span\u003e\r\n\u003cul\u003e\r\n\u003cli data-leveltext=\"\" data-font=\"Symbol\" data-listid=\"2\" data-aria-posinset=\"2\" data-aria-level=\"1\"\u003e\u003cspan class=\"cf0\"\u003eQuart perennials are 5-8\" tall at shipment \u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli data-leveltext=\"\" data-font=\"Symbol\" data-listid=\"2\" data-aria-posinset=\"2\" data-aria-level=\"1\"\u003e\n\u003cspan class=\"cf0\"\u003e2 Gallon perennials are 18-28\" tall at shipment\u003c\/span\u003e\u003c!--EndFragment --\u003e\n\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003cp\u003e\u003cspan class=\"cf0\"\u003e\u003c!-- x-tinymce\/html --\u003e\u003ca href=\"https:\/\/provenwinnersdirect.com\/blogs\/garden-resource-center\/proven-winners-direct-planning-a-garden-101\"\u003eRead our guide to get started with planning a garden\u003c\/a\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"Proven Winners®","offers":[{"title":"2 Gallon \/ Ships Now","offer_id":48045543162104,"sku":"HIBPWP2123130","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Quart \/ Ships Now","offer_id":48045543194872,"sku":"HIBPWP2127800","price":20.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0740\/6600\/2168\/files\/HIBPWP212-CloseUp-1_a7123620-a91d-410e-abea-cb9e64d4be02.jpg?v=1772660616","url":"https:\/\/www.provenwinnersendlessaisle.com\/products\/summerific-holy-grail-rose-mallow","provider":"Proven Winners Endless Aisle","version":"1.0","type":"link"}
