Rose of Sharon shrubs resembles the offspring of a Hollyhock and a Hibiscus! Their maple-leaf shaped foliage confuses further, but these definite hardy Woody Hibiscus family members retain the big satellite blooms in dramatic colors, but just arranged a bit differently!
Blooming later than most flowering shrubs, Rose of Sharon produces beautiful saucer-style blossoms beginning in the summer and blooming until fall! Also known as Common Hibiscus, these romantic and easy-to-grow garden beauties are anything but common!
Like all flowering ornamental bushes, timing is very important when planning out your gardening chore list and pruning schedules!
What is so special about Rose of Sharon? These deciduous plants are native to China and Japan, and Hibiscus syriacus has also been known to go by the names Althea, Rose Mallow, or Chinese Hibiscus.
Their showy blooms are delicate and flutter gently in the breeze, giving life to the landscape! The bloom time is what really sets these shrubs off since the flowers bloom in late summer through fall when many other shrubs are no longer flowering! Its flowers stay open for 1 day and close at night, with more waiting in the wings to open the next day. Their bloom time fills the gap when many other shrubs and trees are not flowering!
Each has the family’s long stamen and anthers held out from the center as if beckoning hummingbirds and bees to land on them! Some varieties have double-flowered and the blooms resemble carnations!
As well as attracting and providing pollen and nectar to a wide range of hummingbirds and butterflies, and bees! I’ve seen Leaf Cutter Bees cutting perfect circles out of the petals to use when constructing their larvae cocoons and I can't think of a better place I’d like to hatch!
Rose of Sharon produces flowers on this year's growth (bloom on new wood). So timing is crucial so as not to remove that year's flowering display!
Prune as needed to shape in late winter or early spring before you see new growth, as that’s where blooms grow. Develop a pruning plan before you start, especially with new plants! It’s in your hands to train them however you want them to grow!
Pruning Rose of Sharon each spring will produce fewer flowers later in the year, but they will be much larger blooms. If you give it occasional pruning, it will produce a larger array of smaller blooms covering the entire shrub!
Often sold as a multi-branched and multi-trunked shrubby form, a few single-stemmed tree-form varieties are also available! This shrub may also be trained as Espalier (training a plant to grow on a trellis or in a small area)!
Lastly, to keep your Althea blooming, deadhead to stop seed production and encourage plenty more blooms to take their place!
Where does Rose of Sharon grow best?
Rose of Sharon shrubs are vigorous, hardy plants with few pest or disease problems, and tolerate heat, humidity, and drought! Easy to grow and forgiving, they are gloriously low maintenance and perfect for busy gardeners and newbies!
Plant your Rose of Sharon tree in full sun to enjoy the boldest blooms in northern climates. They flower best with at least six hours of direct sunlight. In southern planting zones, however, they do appreciate some afternoon shade to protect them from the worst of the summer’s sun.
Rose of Sharon bushes and trees are tolerant of a wide range of conditions, including poor soil, heat, humidity, drought, and air pollution. Shrub Althea is best planted in well-draining, slightly acidic soil. Planting in the soil doesn't stay soggy is important! Don't forget the Nature Hills Root Booster for a lifetime of symbiotic support.
Rose of Sharon does appreciate watering on a consistent basis for best results, while they may seem like they can thrive on neglect, for best results apply a 3-4 inch thick layer of mulch over their roots and water deeply during extended drought and extreme heat of summer. Don’t let them dry out or you may lose out on seeing their flouncy blooms. Fertilize in spring using a formula for flowering shrubs.
If your Rose of Sharon is dropping unopened buds, that means it is stressed! Don’t reach for the fertilizer! Instead:
