Growing 30-60 cm tall, it features two shiny, elliptical basal leaves and smaller, oblong stem leaves. Its greenish-white, vanilla-scented flowers are arranged in a sparse inflorescence and feature a long spur adapted for pollination by nocturnal moths, such as noctuids and hawkmoths. Unlike the closely related Platanthera bifolia, its pollinaria attach between the pollinator's eyes rather than to the proboscis. The plant is specialized for calcareous and neutral soils and depends on mycorrhizal fungi for both germination and growth.

What Diseases Commonly Affect Greater Butterfly-orchid?
TLDR: Greater Butterfly-orchid is susceptible to 3 known diseases. Monitor regularly for early detection.
Root Rot
Root rot is a serious fungal disease that affects the root system of plants, causing them to decay and die. It is primarily caused by overwatering, poor drainage, or soil-borne fungi such as Pythium, Phytophthora, Rhizoctonia, and Fusarium. The disease thrives in waterlogged conditions where roots are deprived of oxygen, making them susceptible to fungal infection.
Overwatering
Overwatering occurs when plants receive too much water, depriving roots of oxygen and causing root rot. This environmental stress is one of the most common causes of houseplant death, as waterlogged soil prevents roots from breathing and functioning properly.
Slugs and Snails
Slugs and snails are mollusks that feed on plant tissue, causing irregular holes in leaves and damage to young seedlings. They are most active at night and in moist conditions, leaving characteristic silvery slime trails. These pests can quickly devastate gardens, especially during wet seasons.
Meaning & Symbolism
Nocturnal fidelity and hidden charm—its vanilla scent and pale flowers fully emerge only at dusk to attract nocturnal pollinators.
