Aloe [ˈaːlo.e]

Common name: Aloe vera · Medicinal aloe · Burn plant

Aloe A genus of several hundred succulent plants from Africa, Madagascar, and the Arabian Peninsula, forming rosettes of thick, fleshy, often toothed leaves that store water. Aloe vera is the best-known member, long cultivated for the soothing gel in its leaves and grown worldwide as a potted houseplant. Aloes thrive in bright light with infrequent watering and need sharply draining soil to avoid rot.

Fun facts

  • Aloe gel was used in ancient Egypt, where it was called the "plant of immortality."
  • The gel inside the leaves is about 99% water, with the remainder containing vitamins, enzymes, and sugars.
  • It readily produces "pups" — baby offshoots at its base that can be separated and potted.
  • Mature plants send up tall flower spikes with yellow, tubular blooms.
