Archontophoenix alexandrae
Also called Picabeen Palm, King Palm, Northern Bangalow Palm, Alexander Palm
In Singapore: Alexandra Palm, Northern Bangalow Palm, King Palm, Majestic Palm, Alexander Palm, 假槟榔 (Grown in Singapore)
Alexandra palm is a tall, solitary feather palm from the rainforests of north-east and central-east Queensland, Australia, widely grown as a garden and street tree. It thrives with warmth, humidity and plenty of water, and is a fast grower from fresh seed.
Archontophoenix alexandrae, commonly known as Alexandra palm, king palm, northern Bangalow palm, or feather palm, is a palm endemic to Queensland, Australia. It was named in honour of Princess Alexandra of Denmark, but is often erroneously referred to by the misnomer Alexander palm.
This species is easily grown from fresh seed, and is very popular in cultivation in Australia, both for private gardens and as a street and park tree. It is fast growing and will tolerate cooler climates outside the tropics where there are no frosts, and has been widely planted in many countries. It has become naturalised in Hawaii.
The native range of this species is north-east and central-east Queensland, from the Melville Range in Cape York Peninsula to south of Gladstone. The altitudinal range is from sea level to 1,000 m (3,300 ft), although it is most commonly found in lowland riparian rainforest alongside river courses and swamps, often in locations that are severely inundated during heavy rain events. Their ability to withstand these conditions allows them to become the dominant species.
The Kuku Yalanji people of Far North Queensland ate the palm heart of this species.
