About Bird of paradise
Strelitzia reginae · also called crane flower, Strelitzia · flowering
Bird of paradise is a striking South African banana relative grown for its paddle leaves and crane-shaped orange flowers. Indoors it grows to roughly 1.5-2 m and needs the brightest spot in the house. Mildly toxic to pets.
Strelitzia reginae is endemic to the Eastern Cape and KwaZulu-Natal of South Africa, where it grows in coastal bush, riverbanks and clearings. Its rigid beak-like spathe sits perpendicular to the stem to form a durable perch for the sunbirds that pollinate it.
Grow in a rich but free-draining loamy mix; the thick fleshy roots resent waterlogging, and a slightly pot-bound clump actually flowers more reliably than one in an oversized container.
Preferred mix: Rich, well-drained loam

Why bird of paradise needs this mix
Bird of paradise flowers hardest in a rich but free-draining loam — fed enough to fuel the display, open enough that the roots never waterlog.
- Flowering is expensive for bird of paradise: producing buds, blooms and seed draws heavily on nutrients and steady moisture, so the soil has to keep delivering all season.
- A loam-based mix holds nutrients and water far more evenly than a light peat mix, which means a longer, more reliable flowering period.
- It still needs sharp drainage — most flowering plants resent cold, wet feet far more than they resent being a little lean.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons bird of paradise struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A thin, hungry or sandy mix gives bird of paradise weak growth and few, short-lived flowers — it simply runs out of fuel.
- A heavy, badly drained soil rots the roots or crown, often over a wet winter, and you lose the plant before it ever flowers again.
- Over-rich, high-nitrogen mixes can push lush leaf at the expense of flowers — balance, not excess, is the aim.
Either starving bird of paradise in a thin mix or drowning it in a heavy, badly drained one. It wants the rich-but-free-draining middle, plus a flowering (higher-potassium) feed in season.
pH — does it matter for bird of paradise?
Most flowering plants, including bird of paradise, do well around pH 6.0-7.0. A cheap soil test is worth it outdoors; one notable exception is any acid-lover (such as some hydrangeas), where pH directly changes flower colour.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
A quality bagged compost works for bird of paradise in pots if you add grit and a flowering feed. In beds, improving the existing soil with compost and ensuring drainage beats any bag.
Drainage and the pot
Free drainage protects the roots and especially the crown over winter — raised beds, grit in the planting hole and never a waterlogged spot. Containers must have a clear drainage hole.
For perennials, refresh the top layer and feed each spring rather than disturbing the roots; for container displays, start with fresh rich mix each season. When the time comes, our repotting guide for bird of paradise covers the timing and technique step by step.
