One of the best known and most widely planted cultivars, award-winning Hibiscus syriacus ‘Oiseau Bleu’ or ‘Blue Bird’ (Rose of Sharon) is an upright deciduous shrub noted for its large, trumpet-shaped, violet-blue flowers, up to 3 in. across (8 cm), adorned with a dark reddish-purple eye surrounding a cream center. Blooming continuously from midsummer to frost, each flower lasts about one day and stands out against the green foliage of lobed, dark green leaves. A very useful, structural shrub for the back of the border or as a flowering hedge.

  • Recipient of the prestigious Award of Garden Merit of the Royal Horticultural Society.
  • Typically grows with a rounded habit to 6-8 ft. tall (180-240 cm) with a spread of 6 ft. (180 cm). This is a sterile cultivar that does not produce viable seed.
  • A full sun lover, this plant is best grown in average, medium moisture, well-drained soils. 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
