Geranium clarkei 'Kashmir Purple' (Kashmir Purple cranesbill) care

Light

Aim for at least 4-6 hours of direct sun on the leaves. Blooms most freely in full sun but tolerates partial shade well, suiting a range of garden positions. Deep shade thins flowering and loosens the habit; light afternoon shade suits hot climates. If your only bright window faces south, that's perfect for geranium clarkei 'kashmir purple' — same window any aroid would fry on.

Watering

Watering geranium clarkei 'kashmir purple': weekly while establishing and in droughts; drought-tolerant once settled. 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. Keep evenly moist for the first season, then water chiefly in dry weather. It thrives in ordinary garden conditions and dislikes only persistent waterlogging.

Soil and pot

Geranium clarkei 'Kashmir Purple' grows best in most moderately fertile soils, including clay. Adaptable and clay-tolerant, unlike the alpine cinereum types. Grows in any reasonably fertile, well-drained-to-average soil across a broad pH range; compost boosts vigour and bloom. 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

Geranium clarkei 'Kashmir Purple' sits happiest at around Ambient outdoor humidity humidity and -15 to 24°C (5 to 75°F). A hardy border perennial needing only normal outdoor conditions. Open spacing and airflow help keep foliage clear of powdery mildew during humid spells. If you keep the room above 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 geranium clarkei 'kashmir purple' sparingly. Low feeder. A spring mulch of compost or a single light balanced feed is plenty. Avoid heavy nitrogen, which favours floppy foliage over flowers. 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 geranium clarkei 'kashmir purple' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Vigorous spread — Running rhizomes can encroach on neighbours in rich soil. Divide every two to three years to keep the clump in bounds and maintain vigour.
• Powdery mildew — Pale-grey film on leaves in dry late-summer conditions. Increase airflow, water at the base, and shear clumps back hard to refresh the foliage.
• Post-flowering sprawl — Growth can flop and brown after the main flush. A hard cut-back restores compact leaves and often a second, lighter bloom.
• Vine weevil — Larvae attack roots and rhizomes of container plants, causing sudden wilting. Inspect rootballs when potting and apply nematode controls if grubs are found.

Propagation

Propagate by division of the rhizomatous clump in spring or autumn, replanting promptly, or by basal cuttings in spring. Seed will not reliably come true to this purple-flowered selection, so divide to keep it true. 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

Geranium clarkei 'Kashmir Purple' is mildly toxic to pets. True hardy Geranium (cranesbill) is not individually listed in the ASPCA Toxic/Non-Toxic database — the ASPCA 'Geranium' listing refers to Pelargonium (geraniol and linalool), a different genus. Cranesbills are widely considered low-risk, but as this cultivar is unlisted, treat with caution and verify with a vet if a pet ingests it. 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.
