Growth Stages

1

Dormancy

May to September

Underground tuber rests; no visible foliage above ground

Maintain slightly dry conditions; store in cool location (8-12°C); reduce watering significantly

2

Sprouting

September to October

New shoots emerge from tuber; first leaves appear

Begin increasing moisture; provide bright indirect light; maintain cool temperatures (12-15°C)

3

Vegetative Growth

October to December

Rosette of narrow, lanceolate leaves develops; plant grows 15-25 cm tall

Keep soil consistently moist; maintain cool conditions; ensure good air circulation; feed lightly with diluted orchid fertilizer

4

Flowering

December to March

Delicate hooded flowers emerge from leaf rosette; green and white coloration; intricate labellum structure

Maintain cool temperatures (10-18°C); keep moist but not waterlogged; provide bright light; avoid moving plant; hand-pollinate if desired

5

Seed Development

March to May

Seed capsules form after pollination; tuber accumulates energy reserves

Leave capsules on plant to mature; gradually reduce watering; allow plant to enter dormancy

Fun Facts

  • 🌱 The genus Pterostylis includes over 100 species, nearly all endemic to Australia and the Pacific region, making Pterostylis concinna part of a uniquely Australasian orchid group.
  • 🌱 The 'greenhood' common name and the distinctive hooded flower shape (formed by the dorsal sepal and petals) is thought to be an adaptation that provides shelter for pollinating insects during their mating ritual.
  • 🌱 Pterostylis orchids undergo an unusual dormancy cycle compared to most plants, with underground tubers resting during hot, dry summers and actively growing during cool, wet winters—the reverse of most Northern Hemisphere temperate plants.
