About Cuming's Medinilla

Medinilla cumingii · also called Cuming's Medinilla, Chandelier Tree · tropical

A spectacular epiphytic shrub from the Philippine island of Luzon, producing pendulous 25 cm (10 in) chandelier-like clusters of hot-pink flowers that mature into deep blue-purple berries. Grown for its bold flowers and large, glossy foliage. Needs warmth, high humidity, and excellent drainage to thrive indoors.

Preferred mix: Coarse, well-aerated bark-based epiphyte mix

Watch for — Leaf scorch / tip browning: Brown leaf tips and edges result from low humidity, direct harsh sun, or fluoride/salt build-up in the soil. Raise humidity, move out of direct sun, and flush the pot with plain water monthly.
