Free flowering, Hibiscus syriacus 'Marina' (Rose of Sharon), often sold as 'Blue Satin', is a dense and bushy deciduous shrub noted for its abundant violet blue flowers resembling hollyhock blossoms. Blooming continuously from midsummer to fall, the large deep royal blue to violet-blue flowers, 4 in. across (10 cm), are adorned with dark reddish-purple throats and conspicuous, protruding, creamy-white tubes of stamens. Each flower lasts about one day, but the plant blooms continuously and heavily until late in the season. The foliage of broadly ovate, three-lobed leaves is dark green. A very useful, structural shrub for the back of the border.

  • Typically grows with an upright habit, up to 6-9 ft. tall (180-270 cm) with a spread of 3-6 ft. (90-180 cm).
  • A full sun to part shade lover, this plant is best grown in average, medium moisture, well-drained soils. Best flower production is obtained in full sun. Prefers moist, organically rich soils, but tolerates poor soils. Tolerant of drought, urban conditions, heat and humidity.
  • Fairly pest and disease free. Watch for leaf spots, blights, rusts, canker and Japanese beetles. 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.
