Hibiscus syriacus - Rose of Sharon

If you are looking for a cold tolerant hibiscus this is the one. Hibiscus syriacus is a deciduous hibiscus that will grow 6 - 12' depending on conditions. This is a fairly upright shrub with a tidy habit, easy to prune and long flowering.

The species itself is Native to China, pink flowering with a red centre, flowering will begin in early summer and continue through until fall.

The cultivars that are available include 'Red Ensigne', (see picture right). In our mind one of the most attractive frost hardy hibiscus. White flowers with contrasting deep magenta red centres. Easily pruned and can be grown as a standard.

Excellent as a 'stand alone shrub' or grown towards the rear of the garden border. As it prunes easily this is a plant that can also be used as a hedge.
