How to Care for Strelitzia

Strelitzia, known as the bird of paradise, is the plant to choose when you want real height and drama. It grows as a fan of enormous paddle shaped leaves on long upright stems, and a mature plant can easily fill a corner from floor to ceiling. The orange and blue flowers that give it its name look exactly like the head of an exotic bird, though they only appear on well established plants.

There are five species in the genus and all of them come from South Africa, growing wild in the Eastern Cape along riverbanks and in open coastal scrub. The most familiar are the orange-flowered Strelitzia reginae and the giant white Strelitzia nicolai.

Here's how to care for them.

How Much Light Does Strelitzia Need?

Strelitzia wants as much bright light as you can give it, and it is one of the few houseplants that genuinely enjoys some direct sun. A south or west-facing window is ideal, and a few hours of sun on the leaves each day will keep it strong and compact.

This is not a plant for a shady corner. In low light it grows slowly, produces smaller leaves on longer weaker stems and will never flower. If you are moving one into a much brighter position, do it over a couple of weeks so the leaves can adjust rather than scorch. Turn the pot every few weeks so the fan of leaves grows evenly instead of leaning towards the window.

How Often Should You Water Strelitzia?

Water when the top 3 to 5 cm of compost has dried out. In spring and summer that usually means once a week, dropping to every two or three weeks in autumn and winter.

Strelitzia is a big plant with a big appetite in the growing season, so do not be shy with it during the warm months, but it stores water in thick fleshy roots and rots if it stays wet in winter. Water thoroughly until it runs from the drainage holes, then drain the pot fully and never leave it standing in water. Like Calathea, it can be a little sensitive to the minerals in hard tap water, which show up as brown leaf edges, so rainwater is worth using if you have it.

What Humidity Does Strelitzia Need?

Strelitzia is comfortable at 50% to 60% humidity, and it copes fine at ordinary household levels.

It comes from a subtropical coastal climate rather than rainforest, so while the air there is reasonably moist, the plant is not dependent on constant humidity the way a Calathea is. Those big leaves do lose water quickly in very dry rooms, and winter heating below about 40% can produce brown crispy edges. Grouping plants together or running a humidifier nearby helps, and wiping the large leaves with a damp cloth keeps them clean and glossy at the same time.

What Temperature Does Strelitzia Need?

Strelitzia grows best between 18°C and 27°C and enjoys warmth through the growing season.

The lowest temperature it can withstand indoors is around 10°C. Below that growth stops and the leaves can yellow and collapse, and cold combined with wet compost will rot the roots. Established plants in mild coastal gardens will tolerate brief dips close to freezing, but an indoor plant should never be pushed near that. If yours spends the summer outside, bring it back in well before autumn nights fall towards 10°C.

How Do You Propagate Strelitzia?

Strelitzia is propagated by division, and it is best done in spring when you are repotting a mature plant.

Slide the plant out of its pot and brush the compost away from the base. You will find a thick rhizome with several separate fans of leaves growing from it, each with its own roots. Choose a section with at least three or four leaves and a good share of roots, and cut cleanly through the rhizome with a sharp knife or a small saw, since it is genuinely tough. Let the cut surfaces dry for an hour or two before potting.

Pot each division into a pot only slightly larger than its roots, using a free draining compost, water it in and keep it warm and bright. Expect it to sulk for several weeks. Strelitzia resents root disturbance, so do not divide more often than you have to, and be aware that division can delay flowering for a couple of years.

Growing from seed is possible but extremely slow, often taking five years or more to reach flowering size.

Why Are My Strelitzia Leaves Turning Yellow?

Overwatering is the most likely cause, particularly in winter. Yellow lower leaves with compost that stays wet for days mean the roots are short of air, so let the top few centimetres dry properly and water less often until the days lengthen again.

Underwatering produces a similar look with dry, shrunken compost and drooping, curling leaves, and a thorough soak fixes it. Because these plants are large and thirsty in summer, they are easy to underestimate.

Check a few other things as well. Yellowing after a cold spell or in a draught points to chill damage. Brown crispy edges alongside yellowing usually mean dry air or hard tap water rather than a watering error. General pale yellowing through spring and summer means the plant is hungry, and Strelitzia is a heavy feeder, so give it a balanced liquid feed every two to four weeks during the growing season. And the oldest outer leaf of the fan yellowing and dying back while new leaves unfurl from the centre is completely normal, since that is exactly how the plant grows.

One thing that worries people unnecessarily: the leaves split. Long tears appear across the blade as the plant matures, and this is not damage or a care mistake. In the wild those splits let wind pass through the huge leaves instead of tearing them from the stem. A mature bird of paradise is meant to look like that.

If you are waiting for flowers, be patient. Plants usually need to be four to six years old and slightly pot bound before they bloom, and they need plenty of direct light, so resist the urge to keep sizing up the pot.
