A strong performer, Hibiscus ‘Dark Mystery’ (Rose Mallow) is a bushy, herbaceous perennial with huge, ruffled white flowers, up to 8-9 in. across (20-22 cm), adorned with a cherry red eye and dark pink veining. The eye-catching blossoms open from abundant flower buds which cover the plant all the way up the stems, making it bloom for much longer than most Hibiscus. Blooming continuously from midsummer to early fall, each flower lasts about one day and stands out against the foliage of beautiful, heart-shaped, dark, wine purple leaves. Perfect backdrop or centerpiece for a sunny border.

  • Typically grows up to 5-6 ft. tall and wide (150-180 cm).
  • Thrives in full sun in average, medium to wet soils. Tolerates some light shade but best flower production and disease resistance occur in full sun. Prefers consistently moist, organically rich soils. Site in locations protected from wind to minimize the risk of wind burn.
  • Plant in perennial borders for dramatic summer blooms. Great along streams or ponds, in bog gardens or in rain gardens.
  • Keep an eye out for blight, canker, rust, leaf spots, aphids, scale, whiteflies and Japanese beetle. Deer resistant.
  • Deadhead spent flowers to maintain a neat appearance.
  • Cut down in spring before new growth appears.
  • It is best to plant Hibiscus in the garden before the heat of the summer arrives, and should be heavily mulched the first winter.
