Hibiscus mutabilis , also known as Confederate rose , Dixie rosemallow , or cotton rosemallow , is a plant known for its striking flowers.
Confederate roses tend to be bushes or tree-like shapes in zones 9 and 10, though more like a perpetual north. The flowers can be double or single and 4-6 inches (10-15 cm) in diameter; they are open white or pink, and turn dark red at night. Varieties 'Rubra' has red flowers. Single bloom flowers are generally cup-shaped. The bloom season usually lasts from summer to autumn. Propagation by cutting cuttings is easiest in early spring, but cuttings can be taken at almost any time. When not frozen, Confederate roses can reach a height of 12-15 feet (3.7-4.6 m) with logs; However, the larger 5-6Ã, ft (1.5-1.8 m) taller shrubs are more distinctive and provide more flowering. This plant has a very fast growth rate. Confederate roses at one time were very common in the Confederate States area, which is how the name generally originated. It grows either in full sun or partial shade, and prefers rich and well-drained soil.

Flower color change
The white flowers in the morning, turn pink during the day and red at night the same. Under laboratory conditions, the change of petal color is slower than the flowers under outdoor conditions. Temperature may be an important factor affecting the rate of discoloration because the white flowers kept in the refrigerator remain white until they are brought out to warm, then slowly turn pink.
Red flowers stay on the plant for a few days before they cancel. Separate single flower weight was 15.6 g (0.55 oz) when white, 12.7 g (0.45 oz) when pink and 11.0 g (0.39 oz) when red. The anthocyanin content of red flowers is three times that of pink flowers and eight times white flowers. There is a significant increase in phenolic content with discoloration. Overall rating of antioxidant properties of H. mutabilis red flowers & gt; pink & gt; white.
Subramanian and Nair postulate that pink and red anthocyanins from H. mutabilis are synthesized independently because there is no reduction of phenolic content. However, Lowry suggests that anthocyanins are formed by direct conversion of flavonols because they have structural similarities.
