Favorite or New Plant

Tree Aloe
Called quiver tree or guliver tree in its native South Africa, over time, Aloe dichotoma develops a dense branching structure atop a thick, bare trunk. It is more treelike than the typical ground level rosette or clumping forms of aloes most gardeners are familiar with. In its native habitat, it can reach 30 feet tall and 23 feet wide and grows in otherworldly looking forests of tree aloes. It tolerates summer heat and winter cold to about 30 degrees F.
