Rose of Sharon Hibiscus syriacus
 

 

 

 

 


 
Rose of Sharon will help bring a bit of tropical beauty to more temperate climates. The big blooms that arrive later in the summer will help revive your garden after the flurry of spring flowers have faded. A true Zone 5. Can be grown in zone 4b areas of Colorado but need maximum protection and heavy mulch- much like Tea Roses. Expect this plant to be more shrub formed than tree like in Colorado growing 6-8ft tall and wide.
It is best to grow Rose of Sharon in full sun, though it can tolerate up to part shade. Don't be surprised if the leaves arrive after most of your other plants, as they start producing the leaves late in spring. Leaves are 2-4" long, often with 3 lobes, and jagged edges.The flowers are 2-5" wide, in shades of white, pink, red, blue, purple, and violet. There is often a different spot of color in the middle of the throat.

Although it is said that Rose of Sharon can be VERY invasive due to the numerous seeds produced in the capsules. This is really only a problem in more southern and humid locations. The blossoms are edible.

 

Be careful when using this as a specimen plant - remember that the leaves appear late in spring and the blooms do not show until later in summer. Better for use in a border with other plants.This is an excellent plant for attracting hummingbirds.

 

Although, Rose of Sharon grows best in moist, well drained soil that contains lots of organic matter, it is able to tolerate a wide variety of soils and is somewhat tolerant of drought conditions. Its the extreme cold winters to watch for. In the cooler zones (where the temperatures fall below -10F in winter), be sure to mulch around the plant well during the winter season.

If you have hot summers, you are in luck - Rose of Sharon actually prefers the heat, and will bloom better.Though it is naturally a multi-stemmed shrub, Rose of Sharon can be trained to have a single trunk, looking more like a tree. It can also be trained as an espalier or shaped into a hedge.

Prune as needed to maintain the shape desired. In winter or early spring, last season's growth should be pruned away, which will help produce bigger blooms.

The buds may drop if the plant is watered too much or too little, or if too much fertilizer is applied.
