Aloe also written Aloë, is a genus containing over 500 species of flowering succulent plants. The most widely known species is Aloe vera. Most Aloe species have a rosette of large, thick, fleshy leaves. Aloe flowers are tubular, frequently yellow, orange, pink, or red, and are borne, densely clustered and pendant, at the apex of simple or branched, leafless stems. Many species of Aloe appear to be stemless, with the rosette growing directly at ground level; other varieties may have a branched or unbranched stem from which the fleshy leaves spring. They vary in color from grey to bright-green and are sometimes striped or mottled. Some aloes native to South Africa are tree-like (arborescent)
If you want a stemless Aloe or one that has a stem like Aloe arborescens please make sure you specify the one you want when you purchase.
