About Pelargonium graveolens 'Grey Lady Plymouth'

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

'Grey Lady Plymouth' is a refined rose-scented geranium with finely cut, grey-green leaves edged in creamy-white. The soft variegation makes it more ornamental but slightly less vigorous than the green types. It carries small pale-pink flowers and the same sweet rose fragrance, thriving in full sun, gritty free-draining soil and frost-free conditions.

Mature size: 50-80 cm tall and 50-70 cm wide; somewhat smaller and slower than non-variegated forms.

Indoor size vs how big it gets in the wild

Pelargonium graveolens 'Grey 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 50-80 cm tall and 50-70 cm wide. In the ground with no restriction it is a completely different plant — somewhat smaller and slower than non-variegated forms. — 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 'Grey 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 in spring and summer with a balanced liquid feed; avoid heavy nitrogen, which can wash out the variegation and produce all-green reversions. stop feeding over winter.
