Calliandra

If you live in an area where the Powder Puff tree isn't hardy, you will have to grow it in a large planter and move it back indoors during the winter. If space in your home is limited, you should consider growing a dwarf variety of the Powderpuff tree, which can be easily managed as a 2-3 foot plant by careful pruning. Indoors, Calliandra needs bright light to full sun, fairly high humidity and an average room temperature of 60°-75°. If the lack of humidity is a problem, you can set the planter on a tray filled with moistened pebbles.

Calliandras 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. Continuously wet conditions should always be avoided. Well established plants can tolerate occasional periods of drought.
