About Swedish Ivy

Plectranthus verticillatus · also called Swedish ivy, Swedish begonia · houseplant

Swedish ivy is a fast-growing, trailing member of the mint family (not a true ivy), prized as an easy, pet-safe houseplant for hanging baskets and shelves. Its one defining need is bright, indirect light with evenly moist but never soggy compost; direct sun scorches its glossy, scalloped leaves and waterlogging rots its shallow roots.

Mature size: Trailing stems reaching around 0.5-1 m long, with a low mounded height of about 10-30 cm; reaches full size within 1-2 years.

Watch for — Leggy or dull growth: A sign of too little light. Move to a brighter, indirectly lit spot and pinch back stem tips to encourage bushier, fuller growth.

Indoor size vs how big it gets in the wild

Swedish Ivy 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 trailing stems reaching around 0.5-1 m long, with a low mounded height of about 10-30 cm. In the ground with no restriction it is a completely different plant — reaches full size within 1-2 years. — 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

Swedish Ivy 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 with a balanced liquid houseplant fertiliser at half to full strength roughly monthly through spring and summer; stop feeding in autumn and winter when growth slows. if a mature plant refuses to flower, switching to a higher-phosphorus, lower-nitrogen feed and giving it brighter light can encourage the spikes of small white-to-pale-lilac blooms.

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

How to keep swedish ivy smaller

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

Trim the longest vines back to the length you want — swedish ivy 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 swedish ivy 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 swedish ivy bigger or faster

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

When swedish ivy outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for swedish ivy:

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

Swedish Ivy size — frequently asked questions

How big does swedish ivy get?

Swedish Ivy reaches trailing stems reaching around 0.5-1 m long, with a low mounded height of about 10-30 cm when grown indoors, and far larger where it grows unrestricted (reaches full size within 1-2 years.). 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 swedish ivy slow or fast growing?

Swedish Ivy is a fast grower. Expect one to three growing seasons — fast vines can add a metre or more of stem in a single good summer. Swedish Ivy 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 swedish ivy take to reach full size?

Roughly one to three growing seasons — fast vines can add a metre or more of stem in a single good summer. Light, pot size and feeding move that timeline more than anything else.
