Strelitzia nicolai, the giant white bird of paradise, is the plant behind the resort look in Australian gardens. Enormous paddle leaves on tall clumping trunks give instant tropical structure, and it does the job in Brisbane, Sydney, Perth and coastal South Australia with very little attention. It is also frequently planted in the wrong place, because almost nobody expects it to reach six metres.

Nicolai or reginae? They are very different plants
Both are sold as bird of paradise and the names are used interchangeably in conversation, which causes a lot of disappointment.
| Plant | Size | Flower | Use |
|---|---|---|---|
| Giant white (S. nicolai) | 4-6 m | White and blue, high in the canopy | Screening, feature clump, resort planting |
| Orange (S. reginae) | 1.5-2 m | Orange and blue, at eye level | Garden beds, borders, pots |
| Juncea (S. parvifolia var. juncea) | 1.5-2 m | Orange, on reed-like stems | Architectural, narrow spaces, very drought hardy |
If you want the famous orange flower at a height you can actually see, plant Strelitzia reginae. If you want a six-metre wall of tropical foliage, plant nicolai. For a narrow bed or a strongly architectural look, juncea has leafless reed-like stems and takes real drought.
Where it grows well in Australia
- Brisbane, the Gold and Sunshine Coasts are ideal. Fast growth, no frost concerns, flowers reliably.
- Sydney and coastal New South Wales grow it very well, and it is a staple of poolside planting here.
- Perth suits it, though sandy soils need compost and consistent summer water while establishing.
- Darwin and tropical Queensland produce the largest, fastest specimens.
- Adelaide and coastal South Australia work in a sheltered sunny spot away from frost pockets.
- Melbourne is marginal. It survives in a warm protected courtyard but grows slowly and may be knocked back in a cold winter.
- Canberra, Tasmania and frost-prone inland are unsuitable outdoors. Grow it in a large pot that shelters over winter.
Plant it further from the house than you think
This is the most common mistake with nicolai. A one-metre nursery plant becomes a four to six metre clump three to four metres across, and the clump spreads outward by suckering over time. Allow at least three metres from a wall, more from a window, and keep it well clear of eaves and gutters. Planted against a house it will eventually push against the wall and block the light it was meant to frame.
The leaves also shred along their ribs in wind. That is normal and healthy - it is how the plant survives storms - but a windy site produces a tattered look. A courtyard, a sheltered pool surround or a spot with a building or hedge on the windward side keeps the foliage intact.
How to plant
- Plant in spring or early summer so it establishes through the warm months.
- Choose full sun to part shade. Full sun gives the densest clump; deep shade makes it leggy with fewer leaves.
- Dig in plenty of compost. These are hungry plants that reward rich soil with faster growth.
- Check drainage. They tolerate heavy summer rain but not permanently wet feet.
- Allow three metres of clearance from buildings, paths and pool edges.
- Water deeply twice a week for the first summer, then reduce.
Growing it in a pot
Nicolai does well in a large container for several years, which is the answer for Melbourne courtyards and anywhere it needs winter shelter. Use a pot at least 500 mm wide with free-draining mix, feed through the growing season, and expect it to stay smaller than an in-ground plant. Potted specimens dry out quickly in summer and need regular water.
Ongoing care
Watering
Water deeply once or twice a week through spring and summer, particularly while the plant is putting out new leaves. Established clumps are surprisingly drought tolerant and can be left alone through mild weather. Reduce watering markedly in winter, when cold wet soil is the main risk.
Feeding
Apply a balanced controlled-release fertiliser in early spring and again in midsummer. Nicolai is a heavy feeder and responds visibly - underfed plants produce smaller, paler leaves and stop putting up new growth.
Pruning and tidying
Cut old brown leaves and spent flower stems off at the base with a sharp saw or loppers. Do not shorten green leaves, since a trimmed leaf simply looks cut and will not regrow from the cut point. To control the size of a clump, remove whole stems at ground level rather than reducing the height of every leaf. Removing outer suckers each year keeps a clump from spreading beyond its space.
Common problems and fixes
- Split and shredded leaves is normal wind behaviour, not disease. Plant in a sheltered position if you want intact foliage.
- Brown leaf edges usually means the plant dried out, or salty water in coastal gardens. Deep soak and mulch well.
- No flowers is usually age or shade. Nicolai typically takes four to five years to flower, and blooms appear high in the canopy where they are easy to miss.
- Yellowing lower leaves is normal turnover as the plant sheds older growth. Several yellowing at once suggests waterlogging.
- Collapse after a cold snap is frost damage. Cut damaged growth back in spring; established clumps usually reshoot from the base.
- Clump outgrowing its space is best fixed by removing whole stems and outer suckers annually rather than by cutting leaves back.
Using it around a pool
Nicolai is one of the best poolside plants in Australia because it does not drop fine litter the way many trees do. The large leaves are easy to pick up, it tolerates reflected heat and light salt, and it delivers the resort look most people want around a pool. Keep the clump three metres back from the water so leaves fall on paving rather than into the pool, and remember the mature width when planning paving.
Frequently asked questions
How big does Strelitzia nicolai get in Australia?
Four to six metres tall and three to four metres wide in a warm coastal climate, reaching that size faster in Brisbane and Darwin than in Perth or Adelaide. It is considerably larger than the orange bird of paradise most people picture.
How far from the house should I plant one?
At least three metres, and further from windows and eaves. The clump spreads by suckering over time, and planting it tight against a wall is the most common regret with this species.
Why are the leaves splitting?
Wind, and it is completely normal. The leaves tear along their ribs so wind passes through rather than tearing the whole leaf off. Plant it in a sheltered courtyard or behind a windbreak if you want the foliage to stay whole.
Will it survive frost in Melbourne or Canberra?
Not reliably. Nicolai is damaged below about 2°C. In Melbourne it can work in a warm sheltered courtyard, and in Canberra or frost-prone inland districts it needs to be a potted plant that shelters through winter.
How long until it flowers?
Usually four to five years from a young plant, and the white and blue flowers appear high in the canopy rather than at eye level. If flowers are the reason you are buying, choose Strelitzia reginae instead - it blooms lower down and much younger.
Can I grow it in a pot long term?
Yes, for several years in a pot at least 500 mm wide with free-draining mix and regular feeding. It stays smaller than an in-ground plant, which is often an advantage, and a pot lets you move it under shelter in colder cities.
