About Australian tree fern
<i>Sphaeropteris cooperi</i>, commonly known as Cooper's Tree Fern or Australian Tree Fern, is a majestic and fast-growing arboreal fern, featuring large, graceful, bright green fronds that can extend several meters long. Its fibrous, scaly trunk gives it a primeval and spectacular appearance, perfect for creating a tropical ambiance in shady gardens, interior courtyards, or as a focal point in expansive landscapes.
Native range
Australia (Queensland and New South Wales)
Care tips
It thrives in partial to full shade, especially in warmer climates, to prevent scorching of its delicate fronds. Consistent and ample watering is essential, keeping the substrate consistently moist but never waterlogged, and regularly misting its trunk and fronds is crucial to mimic its naturally humid environment. The ideal substrate should be rich in organic matter, well-draining, and slightly acidic. A common mistake to avoid is insufficient ambient humidity, which can lead to the frond tips drying out and turning brown.
