Is it normal for bird-of-paradise flowers to take a long time to show?
Bird-of-paradise flowers can be slow to open, but once they do open, the blooms should last for 2 weeks or more. Native to South Africa, bird-of-paradise (Strelitzia reginae) doesn't need much care when grown outdoors in Zones 9 and 10. When grown in full sun or partial shade, it should reach 5 feet in height and grow into a robust clump. In future years, expect to see most of the flowers appear in early summer. Fertilize the plant in spring and again in late summer. About the only problem with this plant is that clumps are difficult to divide, so it's best to leave them undisturbed for many years.
