Euphorbia mammillaris
Also called Corncob Cactus
Euphorbia mammillaris (often mis-spelled Euphorbia mamillaris) is a plant species endemic to Cape Province of South Africa. Euphorbia mammillaris, also known as African or Indian corn-cob, is a fast-growing shrublet, with thick stems that are chalky green, erect and ribbed.
The variegated form, E. mammillaris variegata, is normally a beige-white colour when protected under shade cover, trees, other plants, or rocks; its white stems will become tinged with magenta, fuchsia, and tones of rosy-pink in areas of more sun exposure, times of drought, or in colder weather. Nearing maturity, the plant can reach a foot to two feet tall. Each stem can have from seven to seventeen ribs of thick, hexagonal tubercles growing next to each other vertically, which resembles the look of a corn-cob.
