Euphorbia mammillaris variegata, also known as Variegated Corn Cob Plant, is a fast-growing shrublet with thick stems that are chalky green, erect and ribbed. These stems can turn rosy pink in colder weather.
At maturity, the plant can reach 8-10 inches (20-35 cm) tall. Each stem can have from 7 to 17 ribs with thick hexagonal tubercles placed next to each other vertically, which resembles the look of a corn cob. The spines are pinkish white, thick and pointy like toothpicks, up to 0.4 inches (1 cm) long and scattered around the stem.
From late winter to early summer, Euphorbia mammillaris variegata produces small red and orange flowers from each stem. Will grow well outside as well as inside. Protect from frost.
