Greenhood Orchid Pterostylis curta
ABOUT
The plant known as Small Greenhood has a rather distinctive appearance characterized by its rosette of ground-hugging leaves and a single, prominent flower per stem. The leaves are fleshy and arranged in a circular fashion, forming a basal cluster. They are generally a deep green, which allows them to blend in well with the surrounding vegetation. As for the flower, it's an intricate structure. The flower itself is notably hooded, lending to the name 'Greenhood'. It hangs from the stalk, a nodding head with its petals and sepals merging into a helmet-like shape. The predominant coloring of the flower ranges from green to brown, typically marked with translucent areas and sometimes veined with darker colors, which serve as an attractive pattern to pollinators. The overall impression of the Small Greenhood is one of an elegant yet unassuming plant, well-adapted to its environment with a morphology suited to its ecological niche.

WaterThe Greenhood Orchid, commonly called Pterostylis curta, should be watered regularly but sparingly, as they prefer slightly moist but not wet soils. Water the plant with about 8-10 ounces every week during the active growth period in spring and summer, ensuring the water reaches the root zone. During the dormant period in fall and winter, reduce watering to every other week, and only when the soil surface feels dry to the touch. Overwatering can lead to root rot, so it is crucial to avoid waterlogging. Always use room temperature water to avoid shock to the plant's root system.
LightThe Greenhood Orchid thrives best under low to medium light conditions. It should be placed in a spot that receives bright, indirect sunlight, as direct sunlight can scorch the leaves. An east-facing window or a shaded south-facing window provides the ideal light setting for this plant. If grown under artificial light, ensure it receives sufficient hours of light daily to mimic its natural habitat.
TemperatureThe ideal temperature range for the Greenhood Orchid is between 50°F and 70°F. The plant can tolerate cooler nights, but the temperature should not drop below 40°F, as it may damage the plant. Avoid placing the Pterostylis curta in drafty areas or near heating and cooling sources, which could cause sudden temperature fluctuations. Maintaining a consistent temperature within this range will promote healthier growth.
PruningPruning the Greenhood Orchid is primarily for removing dead or damaged leaves and spent flower spikes to maintain the plant's health and appearance. Pruning should be done after the plant has finished flowering, typically in late summer or fall. Use clean, sharp scissors or pruning shears to make clean cuts without damaging the plant. Pruning is not frequent and should be done as needed to remove old growth and encourage fresh growth in the next season.
CleaningAs needed
SoilGreenhood Orchids prefer a mix of fine pine bark and perlite or coarse sand, with good drainage. Soil pH should be slightly acidic to neutral.
RepottingGreenhood Orchids should be repotted every two years, or when the potting medium begins to break down.
Humidity & MistingGreenhood Orchids thrive best at humidity levels around 50% but can tolerate a range from 40-70%.
Suitable locationsIndoor
Provide bright, indirect light and ensure high humidity for indoor Greenhood Orchids.
Outdoor
Greenhood Orchids grow best in shaded areas with cool, moist conditions.

Life cycleThe Pterostylis curta, commonly known as the Blunt Greenhood, begins its life cycle as a seed dispersed by wind or water. Upon landing in a suitable habitat, often characterized by moist, well-drained soil, the seed germinates in symbiosis with specific mycorrhizal fungi. Through this symbiotic relationship, the seedling develops into a small, non-photosynthetic protocorm before forming its first leaves and photosynthetic structures. The plant then grows into a rosette of ground-hugging leaves, which photosynthesize and provide energy for the subsequent year's growth. In late winter to early spring, the Blunt Greenhood produces a single flower stem with a distinctive hooded flower, which is pollinated by insects, particularly small flies attracted to its deceptive pollination mechanisms. Following pollination, the plant sets seed and enters a period of dormancy during the drier months, completing its annual life cycle.

The most popular method of propagation for the Pterostylis curta, commonly known as the Blunt Greenhood, is through division. This orchid species often forms clumps that can be carefully separated into individual plants, ideally during its dormancy period after flowering and when the foliage begins to die back. To propagate by division, a gardener should gently lift the clump from the ground and clean off any excess soil to reveal the divisions. The offsets, which are smaller bulblets attached to the main tuber, can then be carefully separated, ensuring each piece has at least one growth node. These separated offsets can be replanted at the same depth they were growing previously, approximately 1 to 1.5 inches (2.5 to 3.8 centimeters) deep, in well-draining, orchid-appropriate medium. Watering should be light until new growth appears, signaling successful establishment.
