How Fast Does Rose of Sharon Grow?


Rose of Sharon can grow up to 12 feet high with a slow to moderate growth rate, according to the University of Florida. Young seedlings may grow up to a foot during the first year. Soil conditions, as well as the amount of light and water, can affect the maturity rate of these trees.

Growth Factors

  • Trees planted in partial shade may grow at a slower rate and the amount of pruning may also affect the size of the tree. Pruning is encouraged to produce a fuller tree with more branches and bloom and to discourage branch breakage.

Soil Conditions

  • Rose of Sharon may grow at a slower rate if planted in compacted or clay soil, as the root system may have a more difficult task of developing. Wet soils with poor drainage may encourage disease, also creating a smaller or thinner tree.

Decorative Qualities

  • Rose of Sharon can be added to a landscape as a single ornamental tree or can be planted as a hedge for the look of a line of shrubs. This tree provides a lush amount of foliage and can be very attractive along your property line.

Invasive Qualities

  • Rose of Sharon can be very invasive, as hundreds of seeds are created and dropped to the soil after each blooming season. It is advisable to pull young seedlings as soon as they sprout before they have an opportunity to create strong roots if you do not want many new trees to grow.
