Strelitzia reginae is an evergreen perennial that will reach about 5 feet in cultivation. It is grown for its spectacular flowers. It is a native of South Africa.
Blooming Time: The orange and blue flowers on long stiff stems will bloom intermittently all year long
Culture: Strelitzia reginae need full sun to light shade with intermediate to warm temperatures. In the greenhouse we do not let the nighttime temperatures fall below 55 degrees. We use a soil mix consisting of 2 parts peat moss to 2 parts loam to 1 part sand or perlite. The soil should be kept moist during the growing season. We fertilize weekly with a balanced fertilizer at a rate of 1 Tbs per gallon. Water less frequently in winter. Plants bloom best if crowded in pots, so divide only when necessary.
Propagation: Strelitzia reginae are propagated by division or by seed. Seed is very erratic and may take up to 18 months to germinate.
Strelitzia reginae was featured as Plant of the Week September 22-27, 2000.
