Hibiscus syriacus 'Notwoodone' has pale lavender semi-double flowers with frilly centers of small petals. This is an upright shrub 6 to 8 feet tall. Although each flower lasts only one day, it blooms continuously from mid summer to fall. It is hardy in zones 5 -9. This is a member of the Chiffon series and is sold commercially under the name LAVENDER CHIFFON™. Although when it was named syriacus, it was thought to have originated in Syria, the species is actually native to China and India.
