We called this hardy hibiscus "the holy grail" from its inception because we knew we had something special. There's a whole lot to love about this plant, beginning with its incredible dark, near-black foliage of beautiful, oval shaped leaves. Rich, deep red flowers are enormous at 8-9" across. The red and black colors perfectly complement each other. As an added bonus, once the flowers are finished, bright green calyxes starkly contrast the dark foliage. Use in an area with consistent moisture as a focal point to build your garden around.
These North American native plants bring massive, tropical-looking flowers all the way to zone 4. Although later to emerge than most perennials in spring, these are fast growing plants capable of adding an inch of new growth a day. Excellent at brightening up end of season gardens.
