Grow bird of paradise (Strelitzia reginae) indoors in a container to bring the tropics inside year-round. This dramatic, flowering, evergreen perennial has lush leaves and will produce striking orange flowers if you give it the right care. The flowers, which resemble a tropical bird with bright plumage, bloom in fall and winter. Bird of paradise grows 3 to 4 feet tall and grows outdoors in U.S. Department of Agriculture plant hardiness zones 10 through 12.
Light and Temperature
Grow bird of paradise where it will get direct sun through a window or door. If placed in a west of south facing window during summer, the bird of paradise might require protection from the hot and intense rays of sunlight by using some type of screening like a sheer curtain. In summer, keep the growing area between 65 and 70 degrees Fahrenheit. Ideally, in winter, reduce the temperature to between 50 and 55 F. Keep nighttime temperature at or above 50 F year-round.
Container and Drainage
Use a container that has one or more holes in the bottom to provide enough drainage. The drainage hole is critical. Without it, excess water collects at the bottom of the pot potentially causing root rot problems.
Grow bird of paradise in a planter 1 to 2 inches larger around than the nursery pot, filled with well-draining potting soil or potting mix.
Fertilize once a month through the winter. In spring and summer increase to twice a month. Use 1/2 teaspoon of water-soluble houseplant food, such as a 24-8-16 formula, diluted in 1 gallon of water. Feed the bird of paradise by saturating the soil with the diluted fertilizer mix. After fertilizing, add water if necessary to dampen the soil all the way through.
Water when the surface of the potting starts to look slightly dry through the summer to maintain continuously moist soil. Use enough water each time to dampen the soil all the way through. A good sign you've watered enough it when a little extra water drips out of the hole in the bottom of the pot. In winter, allow the soil to dry out 1 inch deep between waterings.
