Hibiscus Holy Grail

Hibiscus moscheutos ‘Holy Grail’, Hardy Hibiscus ‘Holy Grail’, Rose Mallow ‘Holy Grail’, Summerific® Hardy Hibiscus ‘Holy Grail’

Hibiscus Holy Grail is a dramatic and striking hybrid featuring deep, almost black foliage that provides an intense backdrop for its vivid red blooms. The contrast between the dark leaves and the fiery flowers creates a bold, tropical look that makes this hibiscus a standout specimen in any garden or container. Blooming from mid-summer through fall, Holy Grail delivers long-lasting, show-stopping color that can elevate borders, patio displays, or mixed perennial beds.

This upright perennial grows to approximately 4 ft tall with a similar spread, forming a dense, bushy structure that makes it perfect for creating focal points or mass plantings. Its flowers appear on new growth, ensuring a prolonged bloom period and repeated visual impact throughout the season. The red blooms also attract hummingbirds and pollinators, adding movement and life to your garden.

Ideal for contemporary and tropical-inspired gardens, Hibiscus Holy Grail pairs beautifully with plants that highlight its dramatic foliage, such as ornamental grasses, bright perennials, or contrasting lighter-leafed companions. Its combination of intense foliage and vibrant flowers provides maximum visual interest, making it a versatile and rewarding addition to sunny landscapes and container arrangements alike.

Care Instructions:

Planting: Choose a location with rich, well-draining soil and full to partial sun. Dig a hole twice as wide as the root ball and plant at the same depth as in the container.
Light Requirements: Full Sun to Partial Shade; at least 6 hours of sunlight daily promotes optimal flowering and rich foliage color.
Watering: Keep soil consistently moist but not waterlogged, especially during hot, dry periods.
Fertilizing: Feed with a balanced, slow-release fertilizer in early spring and mid-summer to encourage strong growth and vibrant blooms.
Pruning: Remove spent flowers and any winter-damaged wood in early spring to maintain plant health and encourage new growth.
Companion Plants: Works well with ornamental grasses, bright perennials, or lighter-leafed plants to accentuate the contrast with its dark foliage.
