Pink Rock Jasmine (Flesh-pink Androsace) care

Light

Pink Rock Jasmine needs sun on the leaves, not just bright ambient room light. Full sun is non-negotiable. Grows naturally on exposed south-facing mountain ledges and scree slopes. In cultivation, a south-facing aspect with unobstructed light for most of the day produces the tightest cushions and best flower display. A south or west-facing windowsill in the northern hemisphere is the default; anywhere else, expect the plant to stretch and pale out within a season.

Watering

Water pink rock jasmine very sparingly; driest in winter. The actual day count varies with pot size, light, and season — the finger test (or lifting the pot to feel its weight) is more reliable than a fixed calendar. Empty any drainage saucer afterwards so the pot isn't sitting in water. Water modestly during active spring growth, allowing soil to partially dry between applications. In summer and especially winter, keep the crown nearly dry. Rain protection in winter (alpine house or cloche) is strongly recommended in wet climates to prevent fatal crown rot.

Soil and pot

Pink Rock Jasmine grows best in ultra-sharp draining scree or tufa. Thrives in a mix of 70% coarse granite or limestone grit with 30% loam, or planted directly into drilled tufa rock. Neutral to slightly alkaline pH (6.5–7.5). Rich or moisture-retentive mixes are lethal. A grit top-dressing around the collar is essential. 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

Pink Rock Jasmine sits happiest at around Very low, 20–35% RH humidity and -20°C to 18°C (-4°F to 64°F). Native to the dry, wind-exposed ridges and rocky ledges of the Pyrenees and Alps. Very sensitive to humid, stagnant air, which causes cushion rot. Cultivate in the most open, freely ventilated position available. 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 pink rock jasmine sparingly. Minimal feeding only. A light dusting of slow-release alpine or rock plant fertiliser at the start of spring is the maximum required. Overfeeding destroys the tight cushion habit and induces soft, rot-prone growth. 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 pink rock jasmine in the Growli community. Each is annotated with the most common cause so you know where to start.

• Winter cushion rot — The most frequent cause of plant loss. Water collecting in the hairy rosettes during cold, damp winters causes botrytis and bacterial rot. Grow in an alpine house through winter or protect with a glass pane to shed rain while maintaining airflow.
• Cushion browning in heat — Extended hot, dry periods can cause browning of the central rosettes. Ensure the root run stays cool by planting in tufa or a deep scree bed; a light misting in the cool of the morning can help during extreme summer heat.
• Root aphids — Subterranean aphids attack the root system, causing sudden wilting and yellowing despite adequate watering. Confirm by inspecting roots; treat with a systemic insecticide drench approved for ornamentals or discard and replace badly affected plants.

Propagation

Propagate by removing small, healthy rosettes as cuttings in late spring immediately after flowering; root in pure gritty sand in a cool, shaded frame. Seed sown fresh in autumn and cold-conditioned through winter in a frame germinates sporadically in spring. Division is difficult due to the tight cushion structure. 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

Pink Rock Jasmine is pet-safe. Androsace carnea is not individually listed by ASPCA. The genus Androsace (family Primulaceae) has no documented toxic principles and is considered non-toxic to dogs and cats based on family-level characteristics and available horticultural literature. 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.
