Tree Aloe Hercules makes an ideal specimen plant for a large container or an impressive, drought-tolerant landscape plant in southern zones. As it grows, a central trunk develops and the fleshy green leaves have an attractive rose-tint. Once the plant is mature, green tipped salmon flowers appear sporadically from spring to fall. In its native Africa, youll sometimes see Tree Aloes reaching 20-30 tall. Grow in full sun in a porous cactus soil.
