Introducing 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.
