During the winter, water only if the weather is dry for an extended period.
LightRose of Sharon 'Leopoldii' thrives best in full sun, meaning at least six to eight hours of direct sunlight daily. They can also adapt to partial shade, but flowering may be reduced in less sun.

Life cycleThe life of Hibiscus syriacus 'Leopoldii', commonly known as Rose of Sharon, begins with seed germination, which requires well-drained soil and can occur in spring when temperatures are warm and consistent. The seedling stage follows, where the plant develops its first true leaves and gradually matures into a young plant. During the vegetative stage, the plant experiences rapid growth, producing more leaves and branches, and eventually forming a woody stem as it becomes a well-established shrub. Flowering typically occurs in summer to early fall, showcasing characteristic large, trumpet-shaped blooms that are pollinated by insects, leading to the formation of seed pods. After seeds are dispersed, the plant enters a period of dormancy in the winter, conserving energy and resources until warmer weather returns and the cycle can begin anew. This perennial shrub can live for many years, potentially growing larger and more prolific with each season.
PropogationPropogation time
Late spring to early summer
The most popular method of propagating Hibiscus syriacus 'Leopoldii', commonly known as Rose of Sharon, is through softwood cuttings taken in late spring to early summer. To do this, one should select a healthy, young branch and cut a 4 to 6 inch long (approximately 10 to 15 centimeters) piece, just below a leaf node. The lower leaves are then removed, and the cut end can be dipped in a rooting hormone for better success. This prepared cutting should be placed in a well-draining soil mix, ensuring at least one node is buried where leaves were removed. The cutting needs to be kept moist and in a warm environment with indirect sunlight until roots develop, which typically takes several weeks.
