Pelargonium 'Flower of Spring' (Flower of Spring geranium) care

Light

Most houseplants will scorch where pelargonium 'flower of spring' thrives. Give it the windowsill you'd otherwise leave empty because everything else burned there. Needs full sun for the strongest white variegation and tight growth; shade greens the leaves and weakens the habit. Indoors, the brightest sunny windowsill. 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 2-3 cm of compost dries, roughly every 5-7 days in active growth for pelargonium 'flower of spring', 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 deeply, then let the surface dry out before watering again. Keep barely moist through winter. It tolerates short dry spells far better than waterlogging.

Soil and pot

Pelargonium 'Flower of Spring' grows best in gritty, free-draining loam-based compost. John Innes No. 2 plus perlite or grit for drainage. Prefers neutral to slightly alkaline pH and dislikes constantly wet, heavy mixes. 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 'Flower of Spring' sits happiest at around 30-50% humidity and 10-24°C (50-75°F). Average, drier room air is ideal. Avoid still, humid conditions that encourage botrytis and rust; 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 'flower of spring' sparingly. Feed fortnightly with a high-potash liquid fertiliser through spring and summer to keep foliage bright and encourage bloom; stop feeding in autumn and 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 'flower of spring' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Variegation reverting — Insufficient sun fades the white margins to green; move into full sun to maintain colour.
• Geranium rust — Yellow-ringed brown pustules on leaf undersides. Strip infected leaves, space plants for airflow and keep foliage dry.
• Leggy growth — Low light and no pinching cause stretching. Pinch out growing tips and give maximum light to stay compact.
• Aphids and whitefly — Cluster on soft new growth and leaf undersides; control with insecticidal soap or biological predators early.

Propagation

Very easily from softwood stem cuttings in spring or late summer; 8-10 cm tip cuttings root quickly in gritty compost with warmth and good light. 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 'Flower of Spring' is toxic to pets. The ASPCA classifies Geranium (Pelargonium species) as toxic to cats, dogs and horses, due to the essential oils geraniol and linalool. Signs of ingestion include vomiting, anorexia, depression and dermatitis. Keep 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.
