Not really a palm, but it certainly has a tropical look, with its huge banana-like leaves arranged in a fan pattern. Far too big and invasive for modern suburban gardens. If you can get hold of a plant, you might like to keep it in a pot or contained area for fast tropical effects.
Clean off dead leaves and flowers regularly and remove unwanted suckers to keep it looking tidy.
Where to buy Traveller's Palm
You may find this plant difficult to find commercially. Tropical plant specialists (check the Nursery Guide) might carry it. Alternatively, try Strelitzia nicolai, which is quite similar in appearance and easier to obtain in garden centres.
