Normally, Rose of sharon bushes will be between 8-10 feet tall and have a spread of between 4-6 feet. However there are some varieties of this bush that will only reach a height of between 5-8 feet tall. The blooms of this bush can come in a wide variety of colors including: light blue, lavender, red or white. The Rose of Sharon often blooms late in the summer as well as leafs out late in the summer, so do not give up if it takes longer then you expect for this to occur.
If you wish to give this bush its desired shape, you can do so by pruning it in the winter of its first two growing seasons. This will give the bush one main truck, which is why many people tend to refer to this bush as a tree.
