Plant Highlights: Magnificent architectural fern • Evergreen canopy of graceful fronds • Perfect for shaded gardens • Creates a tropical woodland feel • Long-lived specimen plant
Dicksonia antarctica, commonly known as the Tree Fern, is one of the most striking architectural plants for creating a lush, woodland atmosphere. Its tall fibrous trunk is crowned by a graceful canopy of finely divided evergreen fronds, bringing dramatic texture and a timeless presence to shaded gardens.
Slow growing and exceptionally long-lived, this impressive specimen develops into a beautiful focal point over many years. Supplied at approximately 150cm tall, it provides immediate impact and is ideal for woodland gardens, sheltered courtyards or large containers where its elegant form can be fully appreciated. Its distinctive silhouette pairs beautifully with Hostas, ferns, Heucheras and other shade-loving plants.

Choose a sheltered position in partial or full shade, protected from strong winds that can damage the large fronds. Tree ferns thrive in woodland-style planting where humidity is naturally higher.
Keep the soil consistently moist, particularly during dry weather. In warm periods, water the crown as well as the surrounding soil, as new fronds emerge from the top of the trunk. Container-grown specimens will require more frequent watering than those planted in the ground.
Plant in fertile, humus-rich soil that retains moisture while draining freely. Adding generous amounts of organic matter before planting helps maintain the cool, damp conditions that tree ferns enjoy, especially in Irish gardens.
In colder parts of Ireland or during severe winter weather, protect the crown from prolonged frost, as this is the growing point of the plant. Remove damaged or old fronds in spring as new growth begins to unfurl.
The trunk of a tree fern is not a woody stem like that of a tree but a vertical stem formed over many years. Growth is slow, making each mature specimen a valuable long-term feature that brings lasting character to the garden.
