Variegated Indian Corn Cob (Euphorbia mammillaris var. variegata): A Columnar Euphorbia with Cream-Striped Ribs

Variegated Indian Corn Cob is a striking cultivar of the corn cob euphorbia. It forms a cluster of upright, columnar stems with 7–17 deep ribs, each striped vertically with creamy yellow and green. The stems are studded with prominent, white, spine-bearing tubercles that resemble kernels on a corn cob. Small, yellow cyathia appear at the stem tips. It’s a slow-growing, architectural accent for containers and frost-free beds.
