Hibiscus - Summerific® Holy Grail
A striking perennial rose mallow, Holy Grail is a standout with its dramatic near-black foliage that sets the stage for spectacular 8–9″ deep-red blooms throughout the summer into early fall. These vibrant flowers perched on tall, upright stems provide a stunning focal point in any garden. Growing vigorously to about 48–54″ tall and spreading 54–60″ wide, it's hardy in zones 4–9 and thrives in moist, fertile soil under full sun to part shade. Low-maintenance yet bold, it attracts hummingbirds and butterflies while resisting deer—truly a dramatic, garden-worthy masterpiece.
