Aloe is the name of a plant genus that contains more than 300 species. Most of the aloe species are native to Africa, Madagascar and the Arabian Peninsula. In addition to the familiar cactus-like plant called aloe vera that many people use to soothe sunburns and other skin ailments, this genus has plants that range from grassy succulents to large trees.
Intro: Aloe is a popular succulent plant that produces yellow-orange flowering shoots. It is hardy and does well in plant containers in balcony gardens. Aloe vera plants are usually sold very small, but it is surprising how large they can get â up to 2 feet tall and 2.5 feet wide. There are many varieties of aloe vera that thrive in containers â some completely green and others having white speckles.
