Rose of Sharon are hibiscus shrubs that are winter hardy in temperatures up to -20 degrees. Many are winter hardy in growing zones 5 to 9. Gardeners love the plants due to the beautiful large tropical flowers that are recognized everywhere. Most bushes have plate sized flowers with a long seed pod growing from the middle. The flowers look beautiful on the plant, but do not make for good cut flowers as they die quickly once cut.
These bushes can grow from 3 to 12 feet tall depending on the variety. Rose of Sharon require full sunlight for best flowering performance. Prefers moist yet well drained soil. We recommend adding a layer of mulch to help protect the roots from heat and retain moisture. The bushes are deciduous, meaning the leaves drop during the winter.
