Care at a glance

Light

Friendship Plant is what florists mean by "bright spot, no direct sun" — close enough to a south or east window to feel the brightness, with a sheer curtain or a few feet of distance keeping the sun off the leaves. Bright indirect light keeps the texture and bronze tones strong. Avoid direct sun, which scorches the leaves; in low light it grows leggy and loses colour intensity. A phone lux-meter at the leaf surface should read 1,500-3,000 lux at noon.

Watering

Water friendship plant when the top 2-3 cm of soil is dry, roughly every 5-9 days. 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. Keep lightly moist but allow the surface to dry between waterings. It dislikes both soggy roots and complete drought; reduce watering in winter.

Soil and pot

Friendship Plant grows best in light, well-draining, peat- or coir-based mix. A loose houseplant mix with perlite gives the fast-but-fine roots good drainage and air, preventing the root rot that follows waterlogging. 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

Friendship Plant sits happiest at around 50-60% humidity and 18-27°C (64-81°F). Prefers moderate to high humidity; tolerates average rooms but happier with a pebble tray, humidifier or grouping. Very dry air can brown the leaf edges. If you keep the room above 18 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 friendship plant sparingly. Feed a balanced liquid houseplant fertiliser at half strength every 3-4 weeks in spring and summer; withhold in winter to avoid salt buildup. 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 friendship plant in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Legginess with ageLower stems go bare over time; pinch back regularly and take cuttings to refresh the plant and keep it compact and bushy.
  • Brown, crispy leaf edgesUsually low humidity or underwatering; raise humidity and keep moisture more even, avoiding both extremes of dry and soggy soil.
  • Yellowing lower leavesOften overwatering or poor drainage; let the top of the soil dry between waterings and ensure the pot drains freely.
  • Loss of leaf texture and colourToo little light flattens the quilting and dulls the bronze; move to brighter indirect light, away from direct sun.

Propagation

Extremely easy — root stem-tip cuttings in water or moist mix, where they strike within a couple of weeks; this readiness to share gives the friendship plant its name. 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

Friendship Plant is pet-safe. ASPCA-listed as non-toxic to cats and dogs (Pilea). No recognised toxic principle, making it a safe choice for pet households. 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.

Friendship Plant care — frequently asked questions

What is the common name for Pilea involucrata 'Moon Valley'?

Pilea involucrata 'Moon Valley' is most commonly called Friendship Plant, but it is also known as Moon Valley pilea. The names refer to the same species, so care instructions for Friendship Plant apply identically to anything sold as Moon Valley pilea.

How much light does friendship plant need?

Friendship Plant grows best in bright indirect light (just back from a sunny window). Bright indirect light keeps the texture and bronze tones strong. Avoid direct sun, which scorches the leaves; in low light it grows leggy and loses colour intensity.

How often should I water friendship plant?

Water friendship plant when the top 2-3 cm of soil is dry, roughly every 5-9 days. Keep lightly moist but allow the surface to dry between waterings. It dislikes both soggy roots and complete drought; reduce watering in winter. 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 friendship plant toxic to cats and dogs?

Friendship Plant is pet-safe. ASPCA-listed as non-toxic to cats and dogs (Pilea). No recognised toxic principle, making it a safe choice for pet households.

What USDA hardiness zone does friendship plant grow in?

Friendship Plant is rated for USDA zone 11-12 (indoor in most US homes) and RHS hardiness H1b. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
