About Tillandsia Seleriana

Tillandsia seleriana · also called seleriana air plant, ghost air plant · houseplant

Tillandsia seleriana is a fuzzy, bulbous Central American air plant whose swollen, hollow base is a natural ant home, topped with tapering silver-scaled leaves. A rootless epiphyte, it grows on bark with no soil, prefers soaking and thorough drying over misting, and wants bright light and airflow. It is non-toxic to cats and dogs.

Preferred mix: None — soilless epiphyte

Watch for — Pseudobulb rot: Water lingering in the hollow base after soaking is the main killer. Always drain it upside down and dry it completely between waterings.

Why tillandsia seleriana needs this mix
