About Australian Cabbage Palm

Livistona australis · also called Cabbage Tree Palm, Gippsland Palm · tropical

The Australian Cabbage Palm is a tall, single-trunked fan palm native to eastern Australia, where it forms stands along stream margins and in coastal rainforests. It has glossy, deeply divided fan fronds up to 2 m across and a fibrous trunk. Non-toxic to pets and the most cold-hardy of the Livistona genus.

Mature size: 15-25 m outdoors; 2-4 m as a container specimen

Watch for — Slow indoor growth: Grows significantly more slowly in containers than in the ground; ensure maximum available light to compensate.

Indoor size vs how big it gets in the wild

Australian Cabbage Palm is a tree at heart. Indoors a pot and your ceiling keep it to 15-25 m outdoors, but in the ground it is a different scale of plant entirely (2-4 m as a container specimen). Indoors and in a pot, expect 15-25 m outdoors. In the ground with no restriction it is a completely different plant — 2-4 m as a container 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

Australian Cabbage Palm is a moderate grower. Realistically, expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Its feeding profile backs this up: apply a slow-release palm fertiliser containing micronutrients in spring and summer. supplement with a dilute liquid feed every 6-8 weeks during the growing season for container-grown specimens.

Want this turned into the right next pot at the right moment? The pot size calculator and the australian cabbage palm repotting guide cover when and how much to size up — pot size is one of the biggest levers on how fast australian cabbage palm grows.

How to keep australian cabbage palm smaller

You are not stuck with the maximum size. For australian cabbage palm specifically, these are the levers, in order of impact:

The decisive tool is the secateurs: australian cabbage palm 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 australian cabbage palm 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 australian cabbage palm bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for australian cabbage palm 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 australian cabbage palm light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When australian cabbage palm outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for australian cabbage palm:

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 australian cabbage palm repotting guide. If you want more of this plant instead of a bigger one, the australian cabbage palm propagation guide turns prunings into new plants.

Australian Cabbage Palm size — frequently asked questions

How big does australian cabbage palm get?

Australian Cabbage Palm reaches 15-25 m outdoors when grown indoors, and far larger where it grows unrestricted (2-4 m as a container 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 australian cabbage palm slow or fast growing?

Australian Cabbage Palm is a moderate grower. Expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Australian Cabbage Palm is a tree at heart. Indoors a pot and your ceiling keep it to 15-25 m outdoors, but in the ground it is a different scale of plant entirely (2-4 m as a container specimen).

How long does australian cabbage palm take to reach full size?

Roughly three to six years to reach mature indoor size, gaining a steady amount each growing season. Light, pot size and feeding move that timeline more than anything else.
