Care at a glance

Light

Aim for at least 4-6 hours of direct sun on the leaves. Full sun delivers the richest orange-bronze autumn and winter tints; tolerates light or partial shade, where colour is greener and growth softer. At least half a day of direct sun maximises the colour show. If your only bright window faces south, that's perfect for pheasant tail grass — same window any aroid would fry on.

Watering

Watering pheasant tail grass: weekly while establishing; drought-tolerant thereafter. 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. Water regularly through the first season to root in. Once established it is notably drought-tolerant and prefers free-draining soil; soggy ground causes rot. Occasional deep watering in prolonged drought keeps it looking fresh.

Soil and pot

Pheasant Tail Grass grows best in fertile, free-draining loam, neutral to slightly acidic or alkaline. Adapts to most well-drained soils, including sandy and gravelly types, and tolerates a range of pH. It dislikes heavy, wet clay; improve drainage with grit. Moderately fertile, sharply drained soil gives the best growth and colour. 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

Pheasant Tail Grass sits happiest at around Ambient outdoor humidity and -12 to 30°C (10 to 86°F). An evergreen outdoor grass indifferent to air humidity, thriving in mild maritime climates much like its New Zealand homeland. No humidity management is needed. 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 pheasant tail grass sparingly. Light feeders. A single spring application of balanced slow-release fertiliser or a compost mulch is sufficient; excess nitrogen produces lush green growth at the expense of the prized autumn colour. On poor soils, one annual feed in spring is ample. 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 pheasant tail grass in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Rot in wet soilHeavy, poorly drained or winter-wet ground rots the crown. Plant in sharply drained soil or raised beds and avoid standing moisture.
  • Prolific self-seedingIt can seed about freely and naturalise aggressively in mild climates. Cut back flowering stems before seed ripens and pull unwanted seedlings to keep it in check.
  • Weak autumn colourToo much shade or rich feeding keeps foliage green. Grow in full sun on leaner soil to bring out the orange and bronze tones.
  • Frost damage in hard wintersEvergreen but only moderately hardy; severe cold browns or kills foliage. Mulch the crown in colder zones and comb out damaged growth in spring.

Propagation

Divide established clumps in spring, replanting vigorous sections. Easily raised from its abundant seed sown in spring; self-sown seedlings transplant readily but should be managed where unchecked spread is undesirable. 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

Pheasant Tail Grass is mildly toxic to pets. Anemanthele lessoniana is not individually listed on the ASPCA Toxic or Non-Toxic Plant database. UK horticultural sources (including the RHS) report no known toxic effects, but this is not ASPCA grounding, so a definitive pet-safe label cannot be applied. Treat with caution and verify with a vet. The practical hazard is mechanical irritation from fine blades or seed awns rather than documented chemical toxicity. 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.

Pheasant Tail Grass care — frequently asked questions

What is the common name for Anemanthele lessoniana?

Anemanthele lessoniana is most commonly called Pheasant Tail Grass, but it is also known as pheasant tail grass, wind grass, gossamer grass. The names refer to the same species, so care instructions for Pheasant Tail Grass apply identically to anything sold as wind grass.

How much light does pheasant tail grass need?

Pheasant Tail Grass grows best in direct sun (at least 4-6 hours). Full sun delivers the richest orange-bronze autumn and winter tints; tolerates light or partial shade, where colour is greener and growth softer. At least half a day of direct sun maximises the colour show.

How often should I water pheasant tail grass?

Water pheasant tail grass weekly while establishing; drought-tolerant thereafter. Water regularly through the first season to root in. Once established it is notably drought-tolerant and prefers free-draining soil; soggy ground causes rot. Occasional deep watering in prolonged drought keeps it looking fresh. 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 pheasant tail grass toxic to cats and dogs?

Pheasant Tail Grass is mildly toxic to pets. Anemanthele lessoniana is not individually listed on the ASPCA Toxic or Non-Toxic Plant database. UK horticultural sources (including the RHS) report no known toxic effects, but this is not ASPCA grounding, so a definitive pet-safe label cannot be applied. Treat with caution and verify with a vet. The practical hazard is mechanical irritation from fine blades or seed awns rather than documented chemical toxicity.

What USDA hardiness zone does pheasant tail grass grow in?

Pheasant Tail Grass is rated for USDA zone 8-11 and RHS hardiness H4. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
