These hardy small trees branch out wide with very attractive leaves. Calliandra is a large genus of tropical plants that consists of about 200 species of small trees and evergreen, flowering shrubs. Calliandra haematocephala, commonly known as the Powder Puff Tree, is native to South America. Powder Puffs grow up to 10 feet tall with an equal spread, but dwarf, 3-6 foot varieties are also available. Calliandra grow and flower best if they are grown in full sun, but they tolerate some partial shade, especially in hot summer regions. They should be planted in reasonably fertile, moist but well-drained soil with a pH of 6.0-7.5. Powder Puff plants should be watered regularly and thoroughly to maintain evenly moist soil, especially during the summer growing season.
