Pink powder puff plants are classified as shrubs or small trees. Once included in the pea and legume family of plants, they are now considered a species of the mimosa family.
Pink powder puff plants typically grow 3 to 20 feet tall and have a 2- to 12-foot spread. Flower heads grow as large as 3 inches. This plant blooms primarily in the summer, fall and winter. Alternate flower colors include red and white. Copper-pink leaves eventually turn dark green in color.
Pink powder puff plants are recommended for U.S. Department of Agriculture hardiness zones 9 through 11. They are commonly used as a container or house plants and are tolerant to heat and humidity. Pruning is rarely necessary.
These broadleaf evergreens prefer partial to full sunlight. They grow in a variety of moist soils, including sand and clay, and do best with a pH level of 5.5 to 6.5. For best results, fertilize in the spring.
