Dicksonia antarctica

tree fern

This sought-after fern, will form a thick, tree-like stem as it grows, topped with a crown of large (up to 3m long), filigree-like fronds.

One of the oldest plants in the world, once mature, tree ferns are incredibly impressive, and they'll add a touch of drama to any shady garden.

Native to Australia and south-eastern regions in Asia, they are slow growing, so can take up to 10 years to develop a 30cm tall stem. Try them in a semi-shaded spot, among ferns and woodland plants, as part of an exotic scheme, or beside water.

Dicksonia antarctica is hardy to -10°C, although the foliage may die back at -2°C.

Please note that the photograph shows a mature plant, and as they are quite slow-growing, it may take this young plant up to 30 years to reach that size. Nevertheless, it will still make an attractive addition to a shady garden as it grows!

How to care for Dicksonia antarctica:

For our potted tree ferns, plant in moist but well-drained, humus-rich soil in a sheltered, shady position. Incorporate plenty of organic matter such as leaf mould or compost when planting, and keep the soil consistently damp, especially during dry spells.

For tree fern trunks, stand the trunk upright in a hole deep enough to keep it stable, typically around 20–30cm (8-12in) deep depending on its size. Firm the soil around the base, ensuring good contact, and water thoroughly. Additional supports might be necessary for a few growing seasons to ensure the larger trunks remain stable and upright.

As these plants absorb their nutrients through the stem (which is covered in fibrous roots), it is important to make sure when watering that this is kept moist. They are not fully hardy so will need protection in winter.

In milder areas you can do this by gently stuffing a few handfuls of fallen leaves into the crown.

In colder parts of the country, pack the crown with straw before wrapping it with strips of frost fleece, or over-winter it in an unheated greenhouse. As the new growth starts to emerge in spring, the protection should be removed.
