About Mapu Fan Palm

Licuala mattanensis 'Mapu' · also called Mapu Fan Palm, Licuala Mapu · houseplant

Licuala mattanensis 'Mapu' is a compact, highly ornamental fan palm cultivar from Borneo, prized for its nearly circular, deeply pleated leaves with distinctive dark green colouration and clean segmentation. One of the most popular Licuala cultivars among indoor palm collectors, it demands high humidity and warmth but rewards with exceptional tropical foliage on a manageable, slow-growing plant.

Mature size: Typically 1–2 m tall (3–6 ft) in cultivation; leaves 30–60 cm (12–24 in) across; one of the more compact Licuala species

Indoor size vs how big it gets in the wild

Mapu Fan Palm is a tree at heart. Indoors a pot and your ceiling keep it to typically 1–2 m tall (3–6 ft) in cultivation, but in the ground it is a different scale of plant entirely (leaves 30–60 cm (12–24 in) across; one of the more compact licuala species). Indoors and in a pot, expect typically 1–2 m tall (3–6 ft) in cultivation. In the ground with no restriction it is a completely different plant — leaves 30–60 cm (12–24 in) across; one of the more compact licuala species — 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

Mapu Fan Palm is a slow grower. Realistically, expect a decade or more — slow growers like this add only a few centimetres a year, so expect 8-15+ years to reach their indoor ceiling. Its feeding profile backs this up: feed monthly with a balanced, dilute liquid fertiliser (quarter strength) during the growing season (spring through early autumn). avoid high-phosphorus or high-fluoride fertilisers. include a micronutrient supplement twice yearly to prevent magnesium and iron deficiency. do not feed in winter.

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

How to keep mapu fan palm smaller

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

The decisive tool is the secateurs: mapu fan 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.
Good news: slow growth means topping it once buys you years before it needs doing again.

The keep-it-smaller method, step by step

Pick the new height. Decide how tall you want mapu fan 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 mapu fan palm bigger or faster

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

The biggest lever is light — a tree-type plant in dim light barely gains height; move it brighter.
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 mapu fan palm light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When mapu fan palm outgrows the room (or the pot)

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

Mapu Fan Palm size — frequently asked questions

How big does mapu fan palm get?

Mapu Fan Palm reaches typically 1–2 m tall (3–6 ft) in cultivation when grown indoors, and far larger where it grows unrestricted (leaves 30–60 cm (12–24 in) across; one of the more compact licuala species). 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 mapu fan palm slow or fast growing?

Mapu Fan Palm is a slow grower. Expect a decade or more — slow growers like this add only a few centimetres a year, so expect 8-15+ years to reach their indoor ceiling. Mapu Fan Palm is a tree at heart.

How long does mapu fan palm take to reach full size?

Roughly a decade or more — slow growers like this add only a few centimetres a year, so expect 8-15+ years to reach their indoor ceiling. Light, pot size and feeding move that timeline more than anything else.
