About Footstool Palm

Saribus rotundifolius · also called Round-Leaf Fan Palm, Anahaw Palm · tropical

Footstool palm is a tall, single-trunked fan palm of Southeast Asia and the Philippines, where as the anahaw it is a national symbol. Young plants carry near-circular, glossy, pleated fan leaves; with age the trunk soars and the crown rounds out. Fast-growing for a palm and tolerant of sun once established, it is a handsome tropical landscape and large-container specimen.

Mature size: Can reach 10-20 m tall outdoors over time; stays far smaller, around 2-3 m, as a containerised juvenile.

Watch for — Outgrows indoor space: It is naturally a tall palm and a fast grower, so juveniles eventually outgrow rooms and pots; plan for repotting or eventual relocation.

Indoor size vs how big it gets in the wild

Footstool Palm is a tree at heart. Indoors a pot and your ceiling keep it to can reach 10-20 m tall outdoors over time, but in the ground it is a different scale of plant entirely (stays far smaller, around 2-3 m, as a containerised juvenile.). Indoors and in a pot, expect can reach 10-20 m tall outdoors over time. In the ground with no restriction it is a completely different plant — stays far smaller, around 2-3 m, as a containerised juvenile. — 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

Footstool Palm 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: moderate to heavy feeder when growing. apply a slow-release palm fertiliser with magnesium, potassium, and manganese three to four times across the warm growing season to support its vigour; ease off in cool weather.

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

How to keep footstool palm smaller

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

The decisive tool is the secateurs: footstool 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 footstool 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 footstool palm bigger or faster

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

When footstool palm outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for footstool 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 footstool palm repotting guide. If you want more of this plant instead of a bigger one, the footstool palm propagation guide turns prunings into new plants.

Footstool Palm size — frequently asked questions

How big does footstool palm get?

Footstool Palm reaches can reach 10-20 m tall outdoors over time when grown indoors, and far larger where it grows unrestricted (stays far smaller, around 2-3 m, as a containerised juvenile.). 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 footstool palm slow or fast growing?

Footstool Palm is a fast grower. Expect two to four years from a young plant to a room-filling specimen in good light. Footstool Palm is a tree at heart. Indoors a pot and your ceiling keep it to can reach 10-20 m tall outdoors over time, but in the ground it is a different scale of plant entirely (stays far smaller, around 2-3 m, as a containerised juvenile.).

How long does footstool palm 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.
