About Pelargonium graveolens 'Lady Plymouth'

Pelargonium graveolens 'Lady Plymouth' · also called Lady Plymouth geranium, Variegated rose-scented geranium · herb

'Lady Plymouth' is a classic variegated rose geranium with deeply cut grey-green leaves boldly margined in creamy white. It holds an RHS Award of Garden Merit, releases a strong sweet rose scent and bears small mauve-pink flowers. A tender South African perennial, it wants full sun, sharply drained gritty soil and protection from frost.

Mature size: 60-90 cm tall and 60-80 cm wide in a season; can reach 1 m if grown on over years.

Watch for — Green reversions: Vigorous all-green shoots outcompete the variegated growth; remove them as soon as they appear to keep the cream margins.

Indoor size vs how big it gets in the wild

Pelargonium graveolens 'Lady Plymouth' is a garden shrub whose final size is set more by your secateurs than by the plant — pruning, not luck, decides how big it gets. Indoors and in a pot, expect 60-90 cm tall and 60-80 cm wide in a season. In the ground with no restriction it is a completely different plant — can reach 1 m if grown on over years. — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

Left unpruned it builds a woody framework that gets taller and wider every year; with annual pruning you hold it at whatever size suits the space.

Growth rate and years to mature

Pelargonium graveolens 'Lady Plymouth' is a fast grower. Realistically, expect two to four years from a young plant to a room-filling specimen in good light. Its feeding profile backs this up: feed every 2-4 weeks through the growing season with a balanced liquid feed; keep nitrogen moderate to retain variegation. stop feeding from mid-autumn through winter.

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

How to keep pelargonium graveolens 'lady plymouth' smaller

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

Prune pelargonium graveolens 'lady plymouth' annually at the right time for its type — this is the primary, expected way to control its size.
Remove the oldest, thickest stems at the base each year to keep it open and within bounds.
Growing it in a large container rather than open ground naturally restricts the ultimate size.
Avoid heavy feeding if you want to limit growth — rich soil and lots of nitrogen drive bigger, faster shrubs.

The keep-it-smaller method, step by step

Prune at the right time. Time the cut to pelargonium graveolens 'lady plymouth''s type (after flowering for many spring shrubs, late winter for summer-flowering ones) so you do not lose the next display.
Take out the oldest stems. Remove up to a third of the oldest, thickest stems at the base to renew the shrub and contain it.
Shorten the rest. Cut the remaining stems back to an outward-facing bud at the height and width you want.
Restrict the roots. For a permanent size cap, grow it in a large container rather than open ground.

Plant it in open ground in good soil — far more vigorous than a container-restricted plant.
Full sun (which it wants) plus an annual mulch and feed gives the strongest growth.
Water well through the first establishment years; a settled root system drives the fastest size gain.

Light is almost always the ceiling. The pelargonium graveolens 'lady plymouth' light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.
