Tillandsia ionochroma

A green-leaved, tank-forming Andean Tillandsia with violet-tinged flower bracts (the name means violet-coloured). It grows as an epiphyte in cool, humid montane forest from Venezuela to Bolivia, mostly at 2,000–3,400 m. It needs cool nights, bright filtered light, humid moving air and soft water, and dislikes lowland heat.
