About Philodendron erubescens

Philodendron erubescens · also called Blushing Philodendron, Red-Leaf Philodendron · houseplant

Philodendron erubescens, the blushing philodendron, is a vigorous climbing species with arrow-shaped leaves and reddish-purple stems and undersides. It is the parent of many popular cultivars and grows fast up a moss pole. Easy-going and forgiving, it wants bright indirect light, a chunky moist mix, and vertical support to develop its largest, glossiest leaves.

Mature size: Can climb 1.8-3 m or more indoors with support; leaves reach 20-40 cm as it matures.

Indoor size vs how big it gets in the wild

Philodendron erubescens 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 can climb 1.8-3 m or more indoors with support. In the ground with no restriction it is a completely different plant — leaves reach 20-40 cm as it matures. — 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

Philodendron erubescens is a fast grower. Realistically, expect one to three growing seasons — fast vines can add a metre or more of stem in a single good summer. Its feeding profile backs this up: feed every 2-4 weeks in spring and summer with a balanced liquid houseplant fertiliser at half strength; this fast climber is a moderate feeder. stop in autumn and winter and flush the soil occasionally to prevent salt buildup.

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

How to keep philodendron erubescens smaller

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

Trim the longest vines back to the length you want — philodendron erubescens 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.
Expect to tidy it every few weeks in summer — this is a fast vine that will sprawl if left.

The keep-it-smaller method, step by step

Decide the length you want. Pick the point each vine of philodendron erubescens 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 philodendron erubescens bigger or faster

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

Good light plus a moss pole or trellis triggers the longest, fastest, largest-leaved growth.
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 philodendron erubescens light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When philodendron erubescens outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for philodendron erubescens:

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