Strelitzia reginae is a species of evergreen tropical herbaceous plant, native to South Africa. These regal plants (for which they are named, reginae) are named for the beautiful, orange crane-like flowers that they produce, like birds of paradise. Under the right conditions, including full, southern light exposure, proper humidity and temperature, Bird of Paradise may flower indoors, although this is rare.
Sunlight: Thrives in bright direct to bright indirect light. Can take full sun.
Water: Water every 1-2 weeks, allowing soil to dry out between waterings. Increase frequency with increased light. 
Humidity: Normal room humidity will do, but does best in higher humidity.
Temperature: 65°F-85°F (18°C-30°C). It’s best not to let it go below 60°F (15°C).
Size: Indoors, this plant will reach an ultimate height of about 3-5’ (1-1.5m) and will have a spread of about 2-3’ (0.5-1m).

Common Problems
If you have a cat or a dog, make sure they do not eat it. And hey, neither should humans. Best practice is always to keep houseplants out of reach of small children and pets. The Bird of Paradise is usually pest-free, but if it happens, treat pests as soon as they appear with weekly sprays of horticultural (Neem) oil and regular wipe-downs with a soft rag until they are eradicated.
