This article was prepared with the support of UFL flower delivery. Strelitzia is an evergreen from South Africa whose flowers resemble the crested head of a tropical bird — hence the common name, bird of paradise. The genus honours Queen Charlotte of Mecklenburg-Strelitz, wife of King George III and patron of Kew Gardens. South Africa’s 50-cent coin shows a strelitzia, and the bird of paradise is the official flower of Los Angeles.
Strelitzia belongs to the Strelitziaceae, a family related to bananas. Indoor species have no trunk: leathery grey-green leaves 30–50 cm long on long stalks grow from a thick rhizome and look like banana leaves. The tree-like species develop a palm-like trunk over time.
The inflorescence rises on a sturdy stalk from a leaf axil. A stiff, boat-shaped spathe (the “beak”) opens gradually, releasing 4–8 flowers one after another. In S. reginae the outer sepals are orange and the inner petals bright blue, fused into an “arrow”. In the wild, sunbirds pollinate the flowers: when a bird perches on the arrow, pollen sticks to its feet.
As a cut flower strelitzia lasts 2–3 weeks, which makes it a florists’ favourite for exotic bouquets and interior arrangements. If a spathe hasn’t fully opened, you can gently ease the next flower out with a finger.
Bird of paradise (Strelitzia reginae) is the main houseplant species: 1–1.5 m tall with leaves up to 50 cm and orange-and-blue flowers. With good care it blooms several times a year, each inflorescence lasting 2–4 weeks. The cultivar Mandela’s Gold, bred at Kirstenbosch botanical garden, has golden-yellow sepals.
Giant white bird of paradise (S. nicolai) grows 6–10 m tall and was named after Grand Duke Nicholas Nikolaevich of Russia. Its white flowers with a dark blue arrow emerge from a deep maroon spathe. Indoors it is grown as a large foliage plant and rarely flowers.
White strelitzia (S. alba, syn. S. augusta) is also tree-like, up to 10 m, with pure white flowers, and grows wild only in the southern Cape.
Mountain strelitzia (S. caudata) is a tree up to 6 m from the mountains of southern Africa and Eswatini, with white flowers and a lilac-blue arrow.
Rush-leaved strelitzia (S. juncea) is the oddest: instead of leaf blades it keeps straight, bare 1–2 m leaf stalks. Flowers are like those of S. reginae. It tolerates drought and brief cold and is rare in the wild.
| Factor | Spring — autumn | Winter |
|---|---|---|
| Light | Lots of bright light, 2–4 hours of morning or evening sun is fine. South or west window; balcony in summer. | Brightest spot; grow light for 10–12 hours on short days. |
| Temperature | 20–27 °C | 12–16 °C, not below 10 °C |
| Watering | Generous, when the top 2–3 cm is dry | Moderate, every 10–14 days |
| Humidity | Mist in hot weather, wipe leaves | Keep away from radiators |
| Feeding | Every 2 weeks with a flowering-plant fertiliser | None |
| Repotting | Young plants yearly in spring, mature every 2–3 years | — |
Strelitzia comes from sunny South Africa, and lack of light is the main reason it won’t flower indoors. A south or west window is best; acclimatise it to direct sun gradually to avoid scorch. In summer move it to a balcony or garden, sheltered from strong wind that shreds the leaves. In winter it needs 12–16 °C — that is when flower spikes are initiated.
The thick, fleshy roots store water, so overwatering is more dangerous than underwatering. In spring and summer water generously when the top layer is dry and empty the saucer. Water less in winter. Use settled, room-temperature water, wipe the leaves with a damp cloth and mist in hot weather.
Use a rich, free-draining mix — equal parts loam, leaf mould, peat and sand, or all-purpose compost with perlite — over a drainage layer. Choose a tall, heavy pot: the roots grow deep and a mature plant is top-heavy. A slightly snug pot encourages flowering; an oversized one encourages leaves.
The roots are brittle, so repot by moving the whole root ball into a bigger pot, in spring after flowering. If roots are diseased, clean them, cut out rotten parts and dust the cuts with crushed charcoal.
If everything is right and it still won’t bloom, try a “shock”: keep it at about 12 °C with little water for a month, then bring it back into warmth and start a flowering fertiliser.
The quickest method. After flowering, take a mature plant (5–6 years or older) out of its pot and cut off a side shoot with 2–3 leaves and its own roots. Dust the cuts with charcoal, pot the division in a 15–20 cm pot and keep it warm (about 22 °C) with moderate watering for 2–3 weeks. It may bloom in 2–3 years.
| Problem | Cause and fix |
|---|---|
| Split or yellowing leaves | Splitting along the veins is natural, especially in wind. Yellowing means overwatering, cold or hunger. |
| Curling leaves | Drought, dry air or a sudden move. |
| Root rot | Standing water and cold soil. Repot, remove rotten roots, water less. |
| Scale, mealybugs | Sticky residue, bumps, white fluff. Wipe with soapy water, use a systemic insecticide. |
| Spider mites, thrips | Pale speckles and webbing in dry air. Shower, miticide or insecticide repeated after 7–10 days. |
Cut strelitzia is one of the longest-lasting exotic flowers — 2–3 weeks in a vase. Recut the stem at an angle every 2–3 days and change the water. It pairs well with anthurium, orchids, calla lilies, monstera and palm leaves; 3–5 stems make a striking mono bouquet. Order exotic arrangements in our orchids and exotic flowers section.
In short. Bright sun, generous watering in summer, a cool winter and a slightly snug pot are the four conditions under which strelitzia will produce its “birds of paradise”.
With good care 10–15 years or more; the clump grows and produces more flower spikes with age.
Each inflorescence lasts 2–4 weeks as flowers emerge from the spathe one by one. A mature plant may bloom several times a year, mostly in spring and autumn.
It’s normal: like banana leaves, the blades tear easily along the veins. Less wind and enough humidity mean fewer splits.
Yes, it has no strong scent. It just needs plenty of light and room for its large leaves.
S. reginae is compact (1–1.5 m) with orange and blue flowers and is the one that blooms indoors. S. nicolai is a giant reaching 6–10 m with white flowers; indoors it is grown for its big banana-like leaves and rarely flowers.
Give it the brightest spot with a few hours of direct sun, a deep heavy pot, and water when the top 3–5 cm of soil is dry. Keep it away from cold drafts in winter; in summer it can go out on a balcony. Leaves splitting along the veins are normal for the species, not a disease.
