About Tail-leaf Tolumnia

Tolumnia urophylla · also called Tailed Equitant Orchid, Caribbean Dancing Lady · tropical

Tolumnia urophylla is a miniature equitant orchid from the Caribbean with distinctive strap-like leaves tapering to a fine point, giving it the 'tail-leaf' common name. It produces delicate sprays of small flowers. Like all Tolumnia, it requires excellent drainage, bright light, and good airflow. Pet-safe as an orchid.

Preferred mix: Mounted on cork or tree fern, or in very coarse bark mix
