    Hibiscus syriacus is a larval host plant for the Grey Hairstreak Butterfly.
  • Posted by Marilyn (Kentucky - Zone 6a) on May 23, 2013 12:15 AM concerning plant:
    "H. syriacus is a hardy deciduous shrub. It is upright and vase-shaped, reaching 7–13 feet in height, bearing large trumpet-shaped dark pink flowers with prominent yellow-tipped white stamens. Individual flowers are short-lived, lasting only a day. However, numerous buds are produced on the shrub's new growth, which provides prolific flowering over a long summer blooming period. Shoots make interesting indoor vase cuttings, as they stay green for a long time. In the vase some new flowers may open from the more mature buds. The species has naturalized very well in many suburban areas, and might even be termed slightly invasive, so frequently does it seed around. The flower language is delicate beauty.

    Though it has no autumn color and can be stiff and ungainly if badly pruned, H. syriacus remains a popular ornamental shrub today, with many cultivars.

    Cultivars of H. syriacus are widely planted in areas with hot summers for their very attractive white, pink, red, lavender, or purple large and edible flowers.

    Hibiscus syriacus is fairly easily propagated from either seeds, with variable results, or by layering or cuttings, cloning the original."

    This plant is an old one and was started from seed from a plant that grew in the mountains of southeast Kentucky. Here in western Kentucky, zone 6b/7a, I find it to be quite the spreader. It is not native to the US, so when combined with its invasive tendencies, it might not be very popular. But in its defense, it grows and blooms in areas and at times when nothing else will grow or bloom. We have hot dry summers and quite often by September our blooms have ended. This Rose of Sharon is just getting started by then. It will continue to bloom until November.

    It will also grow with little to no care in soil that is rocky and sparse. Bumble bees love it.

    Downside is aphids love it in late summer so you end up with ants and aphids both. Bees love it too.
