Woolly Torch

Pilosocereus palmeri | Also known as: Pilosocereus leucocephalus | Rating: 0 votes | Print / Pdf

Better known as the woolly torch, pilosocereus palmeri stands tall and erect, with single, eight-ribbed, grey-green stems that are covered in white woolly hairs, creating what looks like a white, woolly torch from a distance. But its truly magnificent aspect is its single, trumpet-shaped flower that grows from the top of the stem each summer. Usually lavender or pink, it has a pale yellow throat and a long protruding stamen. Despite its size, the woolly torch is perfect as a potted plant, in cactus compost and with access to bright filtered light. It demands warm temperatures so life under glass is recommended, watering generously in summer and rarely in winter. Pruning is not necessary.
