The Archontophoenix alexandrae, more commonly known as the Alexander Palm, is a quintessential Australian native palm. It’s renowned for its sleek, grey trunk, which is neatly ringed with scars from old frond bases. What really makes this palm a standout is its vibrant green, swollen crown shaft—the section below the fronds where the new growth emerges. The fronds themselves are a deep green on top and silvery-white underneath, creating a beautiful contrast as they rustle in the breeze. This fast-growing palm is a fantastic choice for adding a touch of the tropics to any garden.
General Care & Usage Tips
- Position: Thrives in a full sun position, but younger plants will appreciate some protection from direct afternoon sun, especially in hot climates.
- Soil: Prefers well-drained, rich, organic soil. Mulching around the base will help retain moisture and keep the roots cool.
- Watering: Water regularly, especially during dry spells and in its first few years of growth. It prefers to have consistently moist soil.
- Fertiliser: Use a slow-release granular palm-specific fertiliser in spring and again in late summer to encourage healthy, strong growth.
- Pruning: Pruning is generally not required, as the fronds are self-cleaning—they fall off cleanly from the trunk when they’re old and brown.
- Caring Tips:
- The Alexander Palm is a good choice for coastal areas as it can tolerate some salt spray.
- It can also be grown in large pots when it’s young, but it’s best suited to being planted in the ground where it can reach its full majestic height.
- Keep an eye out for common pests like scale and mealy bugs, and treat with a horticultural oil if needed.
- Its fast growth makes it an excellent choice if you’re looking for a quick vertical element in your garden design.
- Usage: Perfect for creating a tropical, resort-style feel. Plant it as a specimen tree, use it in a group to form a mini forest, or line a driveway for a grand entrance.
