  • Rose of Sharon (Hibiscus syriacus)

    Hiniscus syriacus
    Photographed July 12.

    A common garden shrub that has become something of a pest, invading hedges especially, from which it is very difficult to extricate. Perhaps the best solution is to let the Roses of Sharon take over the hedge: they make a good, dense hedge themselves, and they have beautiful flowers in a number of different color combinations. In Pittsburgh they happily bloom well into October if the weather cooperates. The typical Mallow-family column of stamens sheds huge amounts of pollen, and these flowers are favorites with bees; below is a bumblebee drunk on pollen.
