Hibiscus 'Holy Grail' (Summerific collection)
Common name: Rose mallow 'Holy Grail'
Huge 8-9" deep scarlet red blooms in mid-summer until early fall.
The near-black foliage compliments nicely with the red flowers.
After flowering, it forms bright green calyxes and really shows off against the foliage.
It is slow to emerge in spring so be patient. It may not pop out of the ground until June.
Use as a main focal point in the garden or use in mass plantings for a colorful show.
Pinch the shoots of young plants in early summer to encourage
branching and more flower stalks to form.
Attracts butterflies and hummingbirds. Deer resistant.
