Cereus trigonodendron

A tree-like columnar cactus up to about 15 m tall, with three-angled stems and large purple flowers, from the warm Amazonian lowlands of Peru, Bolivia and western Brazil. In a pot it stays a fast-growing, angular column that wants heat, strong light and steady watering during growth.
