Rose of Sharon shows off bright white, red, pink, blue and purple flowers. It can also contain a mix of more than one colour. It is an easy way to add lasting summer colour to any garden. While it is native to eastern Asia, it is well adapted to growing in North America.

Planting

Water requirement: Keep well-watered with efficient draining
Well draining, slightly acidic soils.
Rose of Sharon can be planted in fall or spring, as long as there is no risk of frost. It is more popular to plant potted plants than to start seeds indoors and then transplant. Dig a hole twice the width of the pot. Set the plant in, cover and water well.
One problem with growing hibiscus in a container is that it can get very large (up to 12feet). It is best to start seedlings in a 2-4inch pot with draining holes. Do not repot the hibiscus into a container that is more than 2 inches larger than the previous one. It is suggested repotting the plant every spring with fresh potting mix.

Care

The Hibiscus syriacus needs minimal care and continues to thrive despite neglect. A thin layer of organic compost or mulch can be benificial, and it is recommended to add mulch in spring. Do not fertilize in late summer as it can cause new growth which the plant will focus on rather than putting energy into developping strong roots.
This shrub grows at a medium rate, with height increases of 13–24" per year, slow to leaf in the spring
Hibiscus is susceptible to many pests such as ants (which bring aphid eggs to the plant), aphids, Japanese beatles and whiteflies. It can also be susceptible to wilt disease, dieback disease and leaf fungus.

Pruning

Spread: A spread of 6–10 feet at maturity.
Control size and maintain a vase shape silhouette by pruning back hard in early spring. Remove any diseased branches (leaf spot, rust). It may reseed abundantly, so be prepared to remove any unwanted plants appearing in other areas, which can be relocated or shared.

Considerations

Rose of Sharon attracts many pollinators, birds and butterflies. It blooms from mid-summer to fall, when most other shrubs are finished for the season. The seed pods that develop provide winter food for goldfinches, cardinals and wrens.

Styling and Use

The rose of Sharon requires full sun to part shade. Ensure to plant in an area that has good air circulation and provide protection from damaging winds or scorching sun that may burn the foliage.
