Euphorbia aggregata, the pincushion, is a species of flowering plant in the family Euphorbiaceae. It is native to the Eastern Cape province of South Africa. A succulent subshrub, very variable in color and form, it is typically found in deserts and dry scrublands. It is a close relative of Euphorbia ferox and E.pulvinata. Kept as an ornamental by succulent enthusiasts, it eventually forms cushions, with the oldest wild individuals exceeding in diameter and sporting up to 40,000 heads.
