The distinctive silver undersides of the fronds create unique light reflections that add visual interest throughout the day.

Planting and Care Advice

Regular watering and mulching maintain optimal soil conditions, while protection from frost and drying winds ensures plant health. Fertilising with a balanced, slow-release formula encourages lush, vigorous growth and enhances the silvery foliage’s vibrancy.

What are the common names for Cyathea dealbata?

The common names for Cyathea dealbata are Silver Fern, Ponga, and sometimes simply Silver Tree Fern. In New Zealand, "Ponga" is the Māori name and is widely recognized alongside "Silver Fern," which is also an important national symbol.

Can Cyathea dealbata grow in full sun?

Cyathea dealbata generally does not grow well in full sun, especially when young. It naturally thrives in shaded or partially shaded environments, like forest understories, where it is protected from direct, harsh sunlight. Full sun can scorch the delicate fronds, dry out the soil too quickly, and stress the plant. However, mature plants can tolerate brief periods of morning sun if they are well-watered and protected from hot afternoon sun. For best results, plant it in a sheltered, semi-shaded position with consistently moist soil.
