Hibiscus syriacus 'Helene'
Plant Details:
Plant Type: Shrub
Plant Family: Malvaceae
Plant Description: A vigorous flowering shrub, the hibiscus grows with dense multiple stems. It grows upright and can make a good hedge. Summer brings numerous showy, pure-white, five-petaled flowers with dark red to purple eyes. The coarsely-toothed leaves provide a nice backdrop for the attractive flowers. It is tolerant of heat, drought, and poor soils but prefers fertile soils with moderate amounts of water.
Maintenance:
Maintenance Type: Shrub - Thinning
Plant Care: Shrub - Thinning (woody multi-stemmed plants that lose their leaves every winter and look best on older stems): Prune dead, diseased, or rubbing branches. Pruning is best done in late winter to early spring for most shrubs. With spring blooming shrubs, prune after the blooms are spent. Remove up to 1/3rd of the overall shrub, keeping older branches to build up a sturdy, permanent and picturesque framework. Keep in mind that these shrubs bloom directly on older wood or on shoots that come off old wood. Monitor for pests, diseases, or other ailments on a regular basis.
