Hibiscus x Summerific® 'Holy Grail' PP31478

Mallow - Common

Summerific® 'Holy Grail' Common Mallow starts blooming in July and produces a large quantity of deep red 8" flowers through early fall.  The flowers are set off by the purple to black maple-shaped leaves, making for a vividly showy tall perennial in the garden.  Hibiscus 'Holy Grail' is highly tolerant of wet sites, so it is a great addition to ponds, bioswales and sunny rain gardens.  Another amazing beauty for Hans Hansen of Walters Gardens.
