More Information

Description Summerific ‘Holy Grail’ hibiscus (aka rose mallow or Hibiscus moscheutos) from Proven Winners will be one of the true head-turners in your garden or landscape. Just look at the richness and uniqueness of this color scheme: deep red flowers and near-black foliage. The show begins mid-summer and lasts for weeks beyond, providing a dramatic display of enormous dish-shaped blooms. It looks fabulous with yellow flowering plants like black-eyed Susan or coreopsis. Summerific hibiscus from Proven Winners are herbaceous perennials, so unlike their close cousin rose of Sharon, they die back to the ground in fall and begin each year fresh in spring. They are one of the latest perennials to emerge in spring, but watching them transform from tiny buds to big, healthy plants in a matter of weeks is nothing short of delightful. These are great plants for beginners – anyone, really! Details Botanical name: Hibiscus x 'Holy Grail'
Patent: USPP 31,478
Common name: Hibiscus, perennial hibiscus, rose mallow, swamp mallow, hardy hibiscus
Zone: 4 - 9
Sun exposure: Sun (> 6 hours sun)
Height x width: 4-5' tall and wide
Flower color: Red
Foliage color: Black
Season of interest: Summer
Uses: Flower gardens, Landscaping, Specimen, Flowering hedge
How To Grow Soil: Plant in any sunny spot. Can tolerate wet soil once established; if grown in dry conditions, growth and blooming may be compromised.
Light: Full sun (> 6 hours sun) is best.
Water: Average to high.
Space: Min. 4' apart.
Fertilizing: Fertilize in early spring, once the ground has thawed, with a granular rose fertilizer.
Winterizing: No special treatment is required; Stems can be cut off once the plant has gone dormant in late autumn as they do not add any considerable interest. 2-3" of mulch is recommended.
Maintenance: Little needed. Perennial hibiscus is one of the very last plants to emerge each spring. Be patient! Once they begin to show buds, they will start to grow quickly.

Totally happy with my first online purchase from Great Garden Plants

Shipping was very quick. When I received my plants, I found them to be securely packaged and very healthy. Thanks to more summer rain than usual, they took off very well. They bloomed right at planting and a second round of blooms soon.
