About Wollemia Pine

Wollemia nobilis · also called Wollemi pine, dinosaur tree · edible

The Wollemi pine is a 'living fossil' conifer in Araucariaceae, rediscovered in 1994 in a remote Australian canyon. Not a true pine, it bears edible seeds in cones like its monkey-puzzle relatives. It grows well in pots or sheltered mild gardens, needing acidic, moist, well-drained soil, dappled light and protection from hard frost and root rot.

Mature size: Up to 25-40 m in the wild; commonly kept to 1-3 m as a long-lived container or patio specimen.

Watch for — Frost on new growth: Soft new shoots can be damaged by hard frost; shelter young plants and protect or shift containers in severe cold.

Indoor size vs how big it gets in the wild

Wollemia Pine is a tree at heart. Indoors a pot and your ceiling keep it to up to 25-40 m in the wild, but in the ground it is a different scale of plant entirely (commonly kept to 1-3 m as a long-lived container or patio specimen.). Indoors and in a pot, expect up to 25-40 m in the wild. In the ground with no restriction it is a completely different plant — commonly kept to 1-3 m as a long-lived container or patio specimen. — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

It gains real height on a trunk or main stem, adding a tier of leaves a year and eventually reaching for the ceiling — this is a plant you grow up, not out.

Growth rate and years to mature

Wollemia Pine is a fast grower. Realistically, expect two to four years from a young plant to a room-filling specimen in good light. Its feeding profile backs this up: feed in spring and summer with a balanced slow-release or ericaceous-friendly fertiliser at a moderate rate; avoid overfeeding. container plants benefit from an annual top-dress and repotting every 2-3 years.

How to keep wollemia pine smaller

You are not stuck with the maximum size. For wollemia pine specifically, these are the levers, in order of impact:

The decisive tool is the secateurs: wollemia pine can be topped (cut the main growing tip) to cap its height and force a bushier, shorter shape.
Keeping it deliberately pot-bound in a snug container slows the whole plant and limits ultimate size.
Prune in spring so it heals fast; remove the tallest leader back to a node to reset the height.
Expect to top or hard-prune it every year or two — left alone it heads for the ceiling.

The keep-it-smaller method, step by step

Pick the new height. Decide how tall you want wollemia pine and find a leaf node or branch point just below that.
Top the main stem. Cut the main growing tip cleanly just above that node in spring; this permanently caps the height and forces side branches.
Keep the pot snug. Avoid jumping to a much bigger pot — a slightly restricted rootball keeps the whole plant smaller.
Maintain the shape. Prune back the tallest new leaders each spring to hold it at the height you chose.

How to grow wollemia pine bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for wollemia pine the accelerators are:

It already wants the bright light it needs; warmth, a yearly pot-up and spring-summer feed are the accelerators.
Pot up a size every year or two while young; restricted roots are the main thing holding height back.
Feed regularly through the growing season and keep it warm — height comes from sustained good conditions.

Light is almost always the ceiling. The wollemia pine light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When wollemia pine outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for wollemia pine:

The top leaves pressing against or bent by the ceiling — the classic "this is now too tall indoors" sign.
It has to be moved away from a light source it has literally outgrown.
Roots filling the largest pot you can reasonably keep indoors — at that point it is top-or-prune or move it outside (if hardy).

If it is the pot rather than the room, it is a repotting job, not a goodbye — see the wollemia pine repotting guide. If you want more of this plant instead of a bigger one, the wollemia pine propagation guide turns prunings into new plants.

Wollemia Pine size — frequently asked questions

How big does wollemia pine get?

Wollemia Pine reaches up to 25-40 m in the wild when grown indoors, and far larger where it grows unrestricted (commonly kept to 1-3 m as a long-lived container or patio specimen.). It gains real height on a trunk or main stem, adding a tier of leaves a year and eventually reaching for the ceiling — this is a plant you grow up, not out.

Is wollemia pine slow or fast growing?

Wollemia Pine is a fast grower. Expect two to four years from a young plant to a room-filling specimen in good light. Wollemia Pine is a tree at heart. Indoors a pot and your ceiling keep it to up to 25-40 m in the wild, but in the ground it is a different scale of plant entirely (commonly kept to 1-3 m as a long-lived container or patio specimen.).

How long does wollemia pine take to reach full size?

Roughly two to four years from a young plant to a room-filling specimen in good light. Light, pot size and feeding move that timeline more than anything else.
