Borzicactus sepium

A sprawling-to-upright, red-flowered columnar cactus (also treated as Cleistocactus sepium) widespread in the inter-Andean valleys of northern and central Ecuador. It likes even, mild temperatures with cool nights and bright sun, and has no strong cold rest, but it should still be kept drier in the dim months.
