About Teague's Porroglossum

Porroglossum teaguei · also called Teague's Porroglossum · tropical

A miniature, cold-growing epiphyte or terrestrial from Pichincha province, Ecuador at around 2,200 m, named for its discoverer Walter Teague. It bears translucent, bright-purple flowers with long tails on successive spikes that bloom in spring. Its sensitive, fine root system requires cool conditions, consistent but well-draining moisture, and shade.

Preferred mix: NZ sphagnum moss or 70% organic / 30% inorganic blend; small net pot or cork mount

Watch for — Root death from temperature extremes: Temperatures above 22°C cause rapid deterioration of the fine root system. Ensure the growing space stays within 9–18°C at all times. In a cool greenhouse, double-potting with a damp outer pot helps buffer root-zone temperature on unexpectedly warm days.

Why teague's porroglossum needs this mix
