Pelargonium graveolens 'Grey Lady Plymouth' (Grey Lady Plymouth scented geranium) care

Light

Aim for at least 4-6 hours of direct sun on the leaves. Needs 5-6 hours of direct sun to hold its variegation and scent. The pale leaves can scorch in fierce midday glass-magnified heat, so give bright sun with some afternoon relief in very hot spots. If your only bright window faces south, that's perfect for pelargonium graveolens 'grey lady plymouth' — same window any aroid would fry on.

Watering

Watering pelargonium graveolens 'grey lady plymouth': when the top 3-4 cm of soil is dry, roughly every 7-12 days. The number that matters isn't the day of the week — it's how dry the top 2-3 cm of the pot feels. A finger in the soil tells you more than a watering app. After every watering, tip the saucer. The variegated, slightly less vigorous foliage uses water a touch more slowly, so err on the dry side. Water thoroughly, drain freely and reduce sharply in winter.

Soil and pot

Pelargonium graveolens 'Grey Lady Plymouth' grows best in free-draining loam or potting mix with added grit or perlite. Peat-free multipurpose compost lightened with grit or perlite. Sharp drainage is essential; neutral to slightly alkaline pH suits it best. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Pelargonium graveolens 'Grey Lady Plymouth' sits happiest at around 30-50% humidity and 10-24°C (50-75°F). Likes dry to average air with good ventilation. Damp, still conditions promote rust and grey mould on the soft variegated leaves; do not mist. If you keep the room above 10 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed pelargonium graveolens 'grey lady plymouth' sparingly. 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. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on pelargonium graveolens 'grey lady plymouth' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Reversion to plain green — All-green shoots are more vigorous and will dominate; cut them out promptly to preserve the variegated character.
• Leaf scorch on pale margins — The cream edges burn under intense, magnified heat or sudden full sun. Acclimatise gradually and shade from extreme midday glare.
• Rust and grey mould — Favoured by damp, stagnant air. Improve airflow, remove infected leaves and keep foliage dry.
• Stretching and loss of colour — Too little light dulls variegation and stretches stems; move to a brighter position and pinch back.

Propagation

From semi-ripe stem cuttings in summer; always take cuttings from well-variegated shoots, never pure-green reversions. Callus the cut, insert into gritty compost, keep just-moist and warm, and roots form in 3-4 weeks. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Pelargonium graveolens 'Grey Lady Plymouth' is toxic to pets. The ASPCA lists Geranium / Scented Geranium (Pelargonium spp.) as toxic to cats, dogs and horses. Toxic principles are geraniol and linalool; signs include vomiting, anorexia, depression and dermatitis, with cats most sensitive. Keep this plant away from pets. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
