Rose Mallow 'Holy Grail', Hardy Hibiscus 'Holy Grail', Summerific Collection
Noted for its dark foliage and long blooming season, Hibiscus ‘Holy Grail’ (Rose Mallow) is a compact, well-branched, herbaceous perennial with extremely large, deep red flowers, up to 9 in. across (22 cm). The eye-catching blossoms open from abundant flower buds which cover the plant all the way up the stems, making it bloom for much longer than most Hibiscus. Blooming continuously from midsummer to fall, each flower lasts about one day and stands out against the incredibly near-black foliage of beautiful, oval-shaped leaves. As an added bonus, once the flowers are finished, their bright green calyxes starkly contrast with the dark foliage. Perfect backdrop or centerpiece for a sunny border. Great for containers too.
