About Pelargonium odoratissimum

Pelargonium odoratissimum · also called Apple geranium, Apple-scented pelargonium · herb

Pelargonium odoratissimum is a low, sprawling scented pelargonium prized for soft, velvety apple-scented leaves released when brushed. A tender South African perennial, it forms a spreading mound with small white flowers and is grown for fragrance, potpourri and herbal flavouring rather than showy bloom. It thrives in bright light and gritty, free-draining compost.

Mature size: Around 30-45 cm tall and 45-60 cm wide; trailing stems can spread further if unpruned.

Watch for — Leggy, scentless growth: Too little light stretches stems and weakens the apple fragrance. Move to full sun and pinch tips to rebuild a bushy, aromatic mound.

Indoor size vs how big it gets in the wild

Pelargonium odoratissimum 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 around 30-45 cm tall and 45-60 cm wide. In the ground with no restriction it is a completely different plant — trailing stems can spread further if unpruned. — 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

Pelargonium odoratissimum 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 2-3 weeks from spring to late summer with a balanced or slightly high-potash liquid feed at half strength. excess nitrogen produces lush foliage with diluted scent and few flowers. stop feeding over winter.

How to keep pelargonium odoratissimum smaller

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

Trim the longest vines back to the length you want — pelargonium odoratissimum 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 pelargonium odoratissimum 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 pelargonium odoratissimum bigger or faster

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

When pelargonium odoratissimum outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for pelargonium odoratissimum:

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

Pelargonium odoratissimum size — frequently asked questions

How big does pelargonium odoratissimum get?

Pelargonium odoratissimum reaches around 30-45 cm tall and 45-60 cm wide when grown indoors, and far larger where it grows unrestricted (trailing stems can spread further if unpruned.). 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 pelargonium odoratissimum slow or fast growing?

Pelargonium odoratissimum is a moderate grower. Expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Pelargonium odoratissimum 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 pelargonium odoratissimum 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.
