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

Light

Most houseplants will scorch where pelargonium graveolens 'lady plymouth' thrives. Give it the windowsill you'd otherwise leave empty because everything else burned there. Give a minimum of 5-6 hours of direct sun for strong variegation and fragrance. Indoors, the brightest possible window; too little light fades the cream margins and weakens growth. A plant moved abruptly from low light to direct sun bleaches in 48 hours — always acclimatise over a week.

Watering

Aim for when the top 3-4 cm of soil is dry, roughly every 7-12 days for pelargonium graveolens 'lady plymouth', but treat that as a starting point rather than a rule. A south-facing summer windowsill will dry the pot twice as fast as a north-facing winter room. Lift the pot; if it feels noticeably lighter than it did wet, water it. Water thoroughly, then let the compost approach dryness. The variegated foliage is forgiving of short drought but quick to rot in soggy soil; cut back hard in winter.

Soil and pot

Pelargonium graveolens 'Lady Plymouth' grows best in free-draining loam or potting mix with added grit or perlite. A peat-free multipurpose compost opened up with grit or perlite. Excellent drainage is non-negotiable; it prefers neutral to slightly alkaline conditions. 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 'Lady Plymouth' sits happiest at around 30-50% humidity and 10-24°C (50-75°F). Tolerates and prefers average to dry air with steady airflow. Avoid misting and crowding, which encourage rust and botrytis on the soft leaves. 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 'lady plymouth' sparingly. 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. 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 'lady plymouth' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Green reversions — Vigorous all-green shoots outcompete the variegated growth; remove them as soon as they appear to keep the cream margins.
• Faded margins in shade — Insufficient light washes out the white edging and weakens scent; relocate to full sun.
• Pelargonium rust — Orange pustules under the leaves spread in damp, still air. Strip affected leaves, space plants and improve ventilation.
• Overwatering rot — Mushy stem bases and yellowing leaves follow waterlogging. Use gritty mix, water only when dry and never leave standing water.

Propagation

Take semi-ripe cuttings in summer from variegated (not reverted) shoots; callus the cut end, insert into free-draining gritty compost, keep barely moist and warm, and expect rooting in about 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 '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.
