With its bright green foliage and showy flowers, the hibiscus mutabilis is a large shrub (or multi-stemmed tree) that is known for its unique color-changing effect--its flowers open as white but rapidly change colors.
It leaves will drop in the winter and return in the summer as softly hairy with a coarse texture that helps gives this plant its unique, eye-catching appearance. Flowers in three distinctive colors will appear on the shrub at the same time.
One of this plant’s common names, rose cotton, is a result of its round, hairy capsule that dries and releases fuzzy seeds. Some of its other monikers include confederate rose, dixie rosemallow, and cotton rosemallow. It was originally native to Southeastern China and nearby countries but is now found on all continents (with the exception of Antarctica).
A member of the Malvaceae family, the hibiscus mutabilis flowers will typically change color over a three-day period; they first appear deep pink, but then as they die, they take on a darker hue. The color change effect can happen very quickly—white flowers can emerge in the morning and then transform to hot pink or even red by that same evening. They can be found as both single and double-flowered varieties, with blossoms that can range from three to five inches across.

Hibiscus Mutabilis Care
When the hibiscus mutabilis is in bloom, it remains a popular choice at garden centers due to its unusual and captivating beauty as a flowering tree. It’s ideal as a specimen plant, but can also be cultivated as part of a mixed shrub border or as a flowering shrub for foundation plantings.
Gardeners appreciate the fact that the hibiscus mutabilis can add a pop of color (and a little bit of charm) to the garden even late in the season, as many other plants are already starting to hibernate for the winter.
It can be planted as either a large spreading shrub or small multi-stemmed tree, both of which will have huge flowers. Either way, this plant will have a very fast rate of growth.
The hibiscus mutabilis is considered to be low-maintenance but is susceptible to scale insects, mealybugs, aphids and powdery mildew. They are, however, considered to be a deer resistant plant.
The hibiscus mutabilis will grow best when exposed to full sun, but part shade can also be tolerated.
You'll want to water your hibiscus mutabilis tree or shrub freely during its growing season, but water sparingly in the winter months. These plants are considered drought tolerant.
This low-maintenance plant will grow in average, medium, and well-drained soils, however, it does prefer loamy types that are rich in organic matter. It will grow best in neutral or slightly acidic soil.
Temperature and Humidity
The hibiscus mutabilis is not a particularly cold-hardy plant; it can tolerate short periods with temperatures falling to about 23 degrees Fahrenheit when fully dormant. Its top growth will be killed by even slight frost, however, its roots are somewhat hardier. It's even possible for the plant to resprout after a few degrees of frost.
Fertilizer can be applied monthly; just be sure to choose a balanced, liquid variety.
Propagating Hibiscus Mutabilis
The hibiscus mutabilis can be propagated by cuttings that root easily. You’ll want to propagate by seeds sown in spring or semi-ripe cuttings in the summer months.

These hibiscus varieties share similar care requirements with the cotton rose, but offer something a little different in terms of bloom shades and shapes.

You’ll want to prune this plant in the winter after it has bloomed. It can tolerate severe pruning—in fact, doing so will actually help rejuvenate leggy plants. Overall, minimal pruning is required.
