Hibiscus Holy Grail

Introducing a very special hibiscus to brighten up late-season gardens or highlight a landscape focal point. Holy Grail is deep and mysterious, with nearly black foliage and dark, rich red blooms that grow to an impressive 8-9" wide. Once the beautiful flowers have finished their season, vivid green calyxes take their place, contrasting nicely with the dark foliage. Butterflies and other beneficial pollinators will flock to the award-winning flowers throughout the growing season. For best results, plant in a well-drained area with consistent moisture. PP31478
