Hibiscus syriacus 'Diana' (Rose of Sharon)

Rose of Sharon 'Diana', Shrub Althea 'Diana'


Noted for its prolific flower production and long blooming season, award-winning Hibiscus syriacus 'Diana' (Rose of Sharon) is a bushy deciduous shrub with elegant, saucer-shaped, pure white flowers, up to 5 in. across (12 cm), with slightly wavy petal edges. Unlike most hardy Hibiscus, they remain open into the evening. Blooming continuously from midsummer to frost, each flower lasts about one day. They stand out against the green foliage of broadly ovate leaves, which wams up to golden-yellow in fall. A hardy, versatile and undemanding shrub, lasting for years without much effort, and ideal to brighten any garden.

  • Recipient of the prestigious Award of Garden Merit of the Royal Horticultural Society, Gold Medal of the Pennsylvania Horticultural Society.
  • Typically grows with a rounded habit to 4-10 ft. tall (120-300 cm) with a spread of 3-6 ft. (90-180 cm). This variety does not readily re-seed itself.
  • A full sun lover, this plant is best grown in average, medium moisture, well-drained soils. Tolerates part shade. Prefers moist, organically rich soils, but tolerates poor soils. Tolerant of drought, salt, heat and humidity.
  • Fairly pest and disease free. Watch for aphids, mealybugs and thrips. Deer resistant.
  • Plant in shrub borders for dramatic summer blooms. Great flowering shrub for foundation plantings, hedges or screens.
  • Prune to shape in spring. Pruning back to 2-3 buds in late winter may produce bigger blooms.
  • Propagate by semi-hardwood cuttings
