Summerific Holy Grail Hardy Hibiscus (Rose Mallow) – 2 Gallon Pot

One of if not the most impressive of the hardy Hibiscus we’ve ever laid eyes on, ‘Holy Grail’ might well be the holy grail of Hibiscus! It is definitely a super-special one adored for both its foliage and flowers. Dinnerplate-size deep red flowers come early to mid summer and continue well into fall contrasting beautifully with the incredibly deep near-black foliage. This cold hardy Hibiscus makes an unforgettable focal point with bold color and texture for a tropical look and feel to landscapes in USDA Zones 4 to 9.

Growing 4 to 4.5 feet tall and 4.5 to 5 feet wide, the Holy Grail Hibiscus makes a bold and beautiful specimen in the landscape or in large containers. Especially impressive in groupings of three or as a colorful hedge. Because it blooms all summer and into fall, and has such bold foliage, it makes a nice backdrop or centerpiece in flower gardens. A natural in butterfly and hummingbird gardens and for adding a tropical flare to your outdoor living spaces.

Suggested Spacing:  4 feet apart for hedge;  8 feet or more apart for space between plants

Hardy Hibiscus are very easy to grow. They prefer a moist but well-drained soil and plenty of sunshine, though some shade is tolerated. During prolonged periods of summer drought plants will appreciate supplemental water to bloom their best. Maintenance is minimal requiring just one pruning a year to prune plants back to ground when new growth begins to emerge in spring.
