||Hibiscus mutabilis, also known as the Confederate rose or the cotton rosemallow, is a plant noted for its flowers. Confederate roses tend to be shrubby or treelike in Zones 9 and 10, though it behaves more like a perennial further north. Flowers can be double or single and are 4 to 6 inches in diameter; they open white or pink, and change to deep red by evening. The 'Rubra' variety has red flowers. Single blooming flowers are generally cup-shaped. Bloom season usually lasts from summer through fall. Propagation by cuttings root easiest in early spring, but cuttings can be taken at almost any time. When it does not freeze, the Confederate rose can reach heights of 15 to 18 feet with a woody trunk; however, a much bushier, 5 or 6 feet plant is more typical and provides more flowering. These plants have a very fast growth rate.
