Aloe is a genus of succulents native to arid, tropical, and southern Africa, Madagascar, and the Arabian Peninsula. They are characterized by their thick, fleshy, spear-shaped leaves that typically grow in a rosette. Many species, most notably Aloe vera, are famous for the clear, gel-like substance found inside their leaves, which is used for soothing burns and other skin irritations. While they do produce true, colorful flowers on a tall stalk, they rarely flower when grown indoors. Learn more about their care here!
