Cyathea brownii, commonly known as the Norfolk Island Tree Fern, is the largest tree fern species in the world. Tall, elegant and unmistakably prehistoric in character, it forms a single towering trunk that can reach up to 20 metres, crowned with deeply divided fronds that stretch an impressive five to six metres in length. As the plant matures, the trunk becomes smooth and patterned with distinctive oval scars left by fallen fronds, while older fronds hang neatly before dropping cleanly to maintain a tidy silhouette.
With its enormous umbrella crown and statuesque form, Cyathea brownii makes a spectacular feature in gardens that can offer humidity and sheltered conditions. Keep it looking its best by removing spent fronds and ensuring the trunk remains well hydrated. Its limited root system means it readily drinks through its trunk, so regular watering down the trunkāeither with a hose or drip lineāis highly beneficial, especially during hot weather.
Soil: Thrives in deep, moist, well-drained loams.
Conditions: Grows best in a semi-shaded position with consistent moisture.
Size: Height 15m x width 4m
