Althea (Hibiscus syriacus)
Althea – also known as Rose of Sharon – is a favorite of gardeners everywhere with it’s vase shaped growth habit. It is a prolific flowering deciduous shrub that blooms in late summer (early August for me) after most flowering shrubs are done flowering.
Once blooming starts, the bush stay covered in continuous buds, blooming until frost. Rose of Sharon bushes are hardy in USDA zones 4-9. They can get 8 to 10 feet tall with a spread of 4 – 6 feet, however they can be pruned to maintain desired size and shape.
When planted in your garden, Rose of Sharon bushes provides structure and height to your garden and looks great behind perennials. Hummingbirds and butterflies love the flowers. It can also be trained as a tree by allowing a single branch to grow and cutting off all side shoots.
This is an easy care shrub that is heat and drought tolerant and likes full sun to light shade. They are late to leaf out in the spring so be patient.
Rose of Sharon can be planted in spring or fall spacing 6 – 10 feet apart. Mulch well in the spring and water as needed. Flowers are produced on new wood, so prune after blooming or in early spring to shape and reduce size. Pruning back to 2-3 buds per branch will encourage larger flowers.
