Care at a glance

Light

Picture the indirect light an east-facing window gives mid-morning — that's the brightness pink fawn lily grows fastest in. Best under a deciduous canopy offering dappled spring light. Requires bright, indirect light during its spring active period. Tolerates increasing shade as summer approaches. Avoid dense, year-round shade which reduces flowering significantly. You'll know it's right when new leaves come out the same size and colour as the established ones. Smaller, paler new leaves = move closer to the window.

Watering

Aim for regular watering in spring; minimal to none during summer dormancy for pink fawn lily, 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. Needs consistent moisture during active spring growth and flowering. Its native range receives wet winters and springs with summer drought, so plants are adapted to drying out in summer. Avoid irrigation over dormant corms to prevent rot.

Soil and pot

Pink Fawn Lily grows best in moist, well-drained, humus-rich woodland soil. Thrives in fertile, leaf-litter-enriched soil with a slightly acidic pH of 5.5–6.5 and excellent summer drainage. In garden conditions, improve heavy soils with coarse grit and generous leaf mould. Good drainage during summer dormancy is critical. 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 Fawn Lily sits happiest at around 50–70% humidity and −20 to 25°C (−4 to 77°F). Native to the naturally humid Pacific Coast forests of Oregon and northern California. Mulching with leaf mould replicates the moisture-retaining duff layer of its natural habitat and helps sustain adequate humidity during spring growth. If you keep the room above −20 to 25°C 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 fawn lily sparingly. Minimal feeding needed. A top-dressing of well-rotted leaf mould or compost in autumn replenishes organic matter and provides gentle nutrition. Avoid concentrated fertilisers near the corms. No feeding is required during summer dormancy. 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 fawn lily in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Corm desiccation before plantingCorms of Erythronium revolutum are highly susceptible to drying out between lifting and replanting. Purchase from suppliers who store corms in damp sand or sawdust, and plant immediately on receipt. Dry corms fail to establish.
  • Corm rot in summerPoor drainage during summer dormancy is the leading cause of loss. In rainy climates, site under a deciduous tree canopy where summer leaf cover reduces rainfall reaching the soil, or lift corms and store in dry sand.
  • Slow naturalisationPink Fawn Lily spreads slowly by offsets and resents disturbance. Leave plantings undisturbed for at least three to five years to allow colony establishment. Once settled, plants will self-seed and spread gradually.

Propagation

Allow established clumps to naturalise and spread by offsets. Divide only congested clumps during summer dormancy, replanting daughter corms immediately into prepared soil. Self-seeds where happy but seedlings take 4–6 years to reach flowering size. Never let corms dry out during any stage of propagation. 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 Fawn Lily is mildly toxic to pets. The ASPCA does not individually list Erythronium revolutum. As a member of the Liliaceae family, ingestion of corms or foliage may cause gastrointestinal upset in pets and humans. It is not a true lily (Lilium) and does not carry the specific nephrotoxic risk to cats associated with that genus, but caution is warranted. Keep away from pets and children as a precaution. 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.

Pink Fawn Lily care — frequently asked questions

What is the common name for Erythronium revolutum?

Erythronium revolutum is most commonly called Pink Fawn Lily, but it is also known as Pink Fawn Lily, Coast Fawn Lily, Mahogany Fawn Lily. The names refer to the same species, so care instructions for Pink Fawn Lily apply identically to anything sold as Coast Fawn Lily.

How much light does pink fawn lily need?

Pink Fawn Lily grows best in medium indirect light (a couple of metres from a window). Best under a deciduous canopy offering dappled spring light. Requires bright, indirect light during its spring active period. Tolerates increasing shade as summer approaches. Avoid dense, year-round shade which reduces flowering significantly.

How often should I water pink fawn lily?

Water pink fawn lily regular watering in spring; minimal to none during summer dormancy. Needs consistent moisture during active spring growth and flowering. Its native range receives wet winters and springs with summer drought, so plants are adapted to drying out in summer. Avoid irrigation over dormant corms to prevent rot. The finger-test (or lifting the pot to feel its weight) beats a fixed weekly calendar because pot size, light, and season all change how fast the soil dries.

Is pink fawn lily toxic to cats and dogs?

Pink Fawn Lily is mildly toxic to pets. The ASPCA does not individually list Erythronium revolutum. As a member of the Liliaceae family, ingestion of corms or foliage may cause gastrointestinal upset in pets and humans. It is not a true lily (Lilium) and does not carry the specific nephrotoxic risk to cats associated with that genus, but caution is warranted. Keep away from pets and children as a precaution.

What USDA hardiness zone does pink fawn lily grow in?

Pink Fawn Lily is rated for USDA zone 5–9 and RHS hardiness H5. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
