About Anadendrum Michaelii

Anadendrum michaelii · also called Michael's anadendrum · houseplant

Anadendrum michaelii is a rare Southeast Asian climbing aroid grown for its glossy, slightly iridescent lance-shaped leaves and neat vining habit. A relative of Rhaphidophora and Epipremnum, it is a true-jungle understory climber that wants warm, humid, shaded conditions, a moss pole to climb and a loose, fast-draining aroid mix to develop larger adult foliage.

Mature size: Climbs 1-2 m indoors with adult leaves typically 10-20 cm long; a relatively compact, slow-to-moderate grower in cultivation.

Watch for — Stalled growth and small leaves: Cold, dryness or no support keep leaves juvenile; give warmth above 18°C, high humidity and a moss pole so it matures and enlarges.

Indoor size vs how big it gets in the wild

Anadendrum Michaelii does not get tall — it gets long. Size here is about stem length and how you train or cut it, not how much floor it claims. Indoors and in a pot, expect climbs 1-2 m indoors with adult leaves typically 10-20 cm long. In the ground with no restriction it is a completely different plant — a relatively compact, slow-to-moderate grower in cultivation. — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

Growth shows up as lengthening stems that trail down or climb up a support; the plant can be kept tiny or grown metres long from the exact same root system.

Growth rate and years to mature

Anadendrum Michaelii 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: feed every 3-4 weeks during spring and summer with a dilute balanced liquid fertiliser at quarter to half strength; this is a slow-rooting genus that scorches easily, so feed lightly and pause in winter.

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

How to keep anadendrum michaelii smaller

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

Trim the longest vines back to the length you want — anadendrum michaelii takes hard cutting well and bushes out from the cut.
Cut just above a leaf node; each trimmed stem usually branches into two, so pruning makes it fuller, not sparser.
The cuttings root easily in water or mix, so "keeping it smaller" doubles as free new plants.
A trim once or twice a season is usually enough to hold its length.

The keep-it-smaller method, step by step

Decide the length you want. Pick the point each vine of anadendrum michaelii should stop — you can be aggressive; it regrows readily.
Cut just above a node. Snip about 0.5 cm above a leaf node so the stem branches there instead of dying back.
Root the cuttings. Drop the trimmed pieces in water or mix — they root in 2-4 weeks and can fill the same pot for a bushier look.
Repeat as it runs. Re-trim whenever it overshoots; regular light pruning keeps it both smaller and fuller.

How to grow anadendrum michaelii bigger or faster

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

More (indirect) light dramatically lengthens the vines and enlarges the leaves.
Give it something to climb — many vines grow far faster and bigger up a support than trailing.
Feed through spring and summer and keep it consistently watered while it is actively running.

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

When anadendrum michaelii outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for anadendrum michaelii:

Vines pooling on the floor or wrapping past where you want them — purely a trimming cue, not a repot one.
Bare, leggy stems with leaves only at the tips (usually a light problem, not a size one).
A tangled mass that has outrun its support and needs cutting back and re-training.

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

Anadendrum Michaelii size — frequently asked questions

How big does anadendrum michaelii get?

Anadendrum Michaelii reaches climbs 1-2 m indoors with adult leaves typically 10-20 cm long when grown indoors, and far larger where it grows unrestricted (a relatively compact, slow-to-moderate grower in cultivation.). Growth shows up as lengthening stems that trail down or climb up a support; the plant can be kept tiny or grown metres long from the exact same root system.

Is anadendrum michaelii slow or fast growing?

Anadendrum Michaelii is a moderate grower. Expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Anadendrum Michaelii does not get tall — it gets long. Size here is about stem length and how you train or cut it, not how much floor it claims.

How long does anadendrum michaelii 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.

How do I keep anadendrum michaelii smaller?

Trim the longest vines back to the length you want — anadendrum michaelii takes hard cutting well and bushes out from the cut. Cut just above a leaf node; each trimmed stem usually branches into two, so pruning makes it fuller, not sparser. The cuttings root easily in water or mix, so "keeping it smaller" doubles as free new plants. A trim once or twice a season is usually enough to hold its length.

How can I make anadendrum michaelii grow bigger or faster?

More (indirect) light dramatically lengthens the vines and enlarges the leaves. Give it something to climb — many vines grow far faster and bigger up a support than trailing. Feed through spring and summer and keep it consistently watered while it is actively running.
