One of the most striking foliage palms available, Johannesteijsmannia altifrons, commonly known as the Diamond Joey Palm, is still relatively little known but highly sought after by collectors.
An understory species from the rainforests of Malaysia, this palm grows to around 3–5 metres in height but has no visible trunk. It is grown almost entirely for its foliage, which forms a dramatic architectural feature in shaded gardens.
The leaves are large, diamond-shaped as the name suggests, undivided, and heavily pleated, giving the plant a bold and sculptural appearance.
Growing conditions and care
Although more tolerant of cooler conditions than many tropical palms, Johannesteijsmannia altifrons performs best in warm, humid environments.
It prefers a protected position in shade to dappled shade, with rich, well-drained soil that remains consistently moist. A subtropical climate is ideal, however it can be grown in warm temperate areas if sheltered from cold, dry winds.
Cold and drying conditions are not suitable, and exposure to wind can quickly damage the foliage.
One of the key challenges with this species is its sensitivity to root disturbance. It does not respond well to transplanting or rough handling, so care should be taken when planting or repotting.
It can be grown indoors in large, well-lit spaces such as atriums or commercial buildings, provided humidity is maintained and it is kept away from air conditioning.
This is an understory plant from the rainforest of Malaysia and although it will reach around 3 – 5m in height it has no real trunk, this palm tree is all about foliage.
The leaves are diamond shaped as the name suggests, they are not divided at all, but are heavily pleated.

Comparison to similar palms
Johannesteijsmannia altifrons is often compared to Licuala species due to its bold foliage, however there are key differences:
- Unlike Licuala, the leaves are not fan-shaped but remain entire and diamond-like.
- It has a more upright, architectural form compared to the rounded habit of many Licuala.
- It is generally more sensitive to root disturbance than most commonly grown shade palms.
Compared to other understory palms, the Diamond Joey Palm stands out for its large, undivided leaves and strong visual impact, making it a feature plant rather than a filler species.
