species of flower plant with 3 colours found by Carolus Linnaeus
Hibiscus mutabilis, also known as the Confederate rose, Dixie rosemallow, cotton rose or cotton rosemallow, is a plant long cultivated for its showy flowers. Originally native to SE China and adjoining countries, it is now found on all continents except Antarctica.
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 4–6 in (10–15 cm) 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 12–15 ft (3.7–4.6 m) with a woody trunk; however, a much bushier plant 5–6 ft (1.5–1.8 m) high is more typical and provides more flowering. These plants have a very fast growth rate. The Confederate rose was at one time very common in the area of the Confederate States of America, which is how its common name was derived. It grows well in full sun or partial shade, and prefers rich, well-drained soil.
In cultivation in the UK, Hibiscus mutabilis has gained the Royal Horticultural Society's Award of Garden Merit.
