Matucana is a South American cactus genus native mainly to the Peruvian Andes, where many species grow in rocky, mountainous environments. These plants are generally small to medium-sized, with rounded or slightly flattened bodies, pronounced ribs and attractive spination. Their most notable feature is their vivid, funnel-shaped flowers, which may appear in shades of red, orange, pink or yellow. Matucana cacti are appreciated for the contrast between their compact, textured bodies and their unusually bright blooms.
