Robust, slow-growing, eventually widely branched tree, resembling an inside-out umbrella in outline when mature. Tufted or rosetted, glaucous, mid-to dark green leaves, 30-60cm long, are linear-lance-shaped and spine-tipped. Mature plants produce terminal panicles, up to 30cm long, white-tinged green flowers in summer, followed by large, spherical, orange-red fruit.
