Care at a glance

Light

Picture the indirect light an east-facing window gives mid-morning — that's the brightness nodding greenhood grows fastest in. Requires shaded to filtered indirect light during the growing season, mimicking the understorey of Australian eucalyptus and wattle woodland. A north-facing or shaded east-facing window is ideal. Direct sun will scorch the soft foliage. 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 lightly moist during active growth (autumn–spring), roughly every 5-8 days for nodding greenhood, 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. Maintain gentle but consistent moisture during autumn through spring. Let the surface dry slightly between waterings but never dry out fully. Cease watering almost completely once leaves yellow and wither in late spring, and keep dry through summer.

Soil and pot

Nodding Greenhood grows best in gritty woodland mix: coarse sand, leaf mould, and perlite. A well-draining, slightly acidic mix is best. Combine coarse propagating sand with leaf mould or coco coir and perlite. Avoid heavy potting composts. Shallow pots with generous drainage holes suit the shallow root system. 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

Nodding Greenhood sits happiest at around 50-65% humidity and 4-20°C (39-68°F). Moderate humidity suits this cool-temperate species. Avoid dry, overheated rooms. Cool, fresh air circulation is more beneficial than attempting very high humidity. If you keep the room above 4 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 nodding greenhood sparingly. Apply a very dilute orchid fertiliser at quarter strength once monthly during the growing season from autumn to early spring. This species is not a heavy feeder; excessive nutrition leads to poor flowering. 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 nodding greenhood in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Summer tuber rotThe most common problem — watering during dormancy rots tubers rapidly. Keep completely dry from late spring to early autumn.
  • Heat stressCannot tolerate temperatures consistently above 25°C. Move to the coolest room or a cold frame in summer.
  • Slug damage to new growthEmerging shoots in autumn are extremely vulnerable to slug predation. Protect immediately with physical barriers or organic pellets.
  • Poor refloweringPlants that fail to re-flower after the first year are often getting too much warmth or moisture in summer, preventing proper tuber rest.
  • AphidsEmerging shoots may attract aphids in autumn. Treat promptly with insecticidal soap.

Companion plants

Nodding Greenhood pairs well with Pterostylis curta, Pterostylis concinna, Thelymitra, and Diuris. These are species with similar light and water needs, so you can group them in the same room or on the same shelf and water as a batch.

Propagation

Naturally produces daughter tubers during the growing season. After foliage dies back in late spring, carefully separate offset tubers from the parent tuber and replant individually in fresh, gritty woodland mix. 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

Nodding Greenhood is pet-safe. Not individually listed by the ASPCA; the Orchidaceae family is broadly considered non-toxic to cats and dogs, and Pterostylis belongs to this family. 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.

Nodding Greenhood care — frequently asked questions

What is the common name for Pterostylis nutans?

Pterostylis nutans is most commonly called Nodding Greenhood, but it is also known as Nodding Greenhood Orchid, Nodding Hood. The names refer to the same species, so care instructions for Nodding Greenhood apply identically to anything sold as Nodding Hood.

How much light does nodding greenhood need?

Nodding Greenhood grows best in medium indirect light (a couple of metres from a window). Requires shaded to filtered indirect light during the growing season, mimicking the understorey of Australian eucalyptus and wattle woodland. A north-facing or shaded east-facing window is ideal. Direct sun will scorch the soft foliage.

How often should I water nodding greenhood?

Water nodding greenhood lightly moist during active growth (autumn–spring), roughly every 5-8 days. Maintain gentle but consistent moisture during autumn through spring. Let the surface dry slightly between waterings but never dry out fully. Cease watering almost completely once leaves yellow and wither in late spring, and keep dry through summer. 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 nodding greenhood toxic to cats and dogs?

Nodding Greenhood is pet-safe. Not individually listed by the ASPCA; the Orchidaceae family is broadly considered non-toxic to cats and dogs, and Pterostylis belongs to this family.

What USDA hardiness zone does nodding greenhood grow in?

Nodding Greenhood is rated for USDA zone 8-10 (cool greenhouse in most climates; outdoor in mild temperate zones) and RHS hardiness H4. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
