Edible Types of Aloe Plants

Note: Unpeeled leaves of the aloes are not edible. They contain high levels of anthranoids, which are toxic. Likewise, gel should not necessarily be prepared from the leaves yourself. Even with the most careful separation of the leaf shell, aloin can get into the gel. This ingredient is also toxic.

Aloe arborescens

  • Bush-like growth
  • 60 to 80 cm long inflorescence
  • Bright red to scarlet flower color

Aloe arborescens is not only edible, but also approved as a medicinal plant. The juice from the leaves can heal burns.

Aloe ferox

This tree aloe is also known under the name Cape aloe or bitter aloe. It has its origin in the arid regions of South Africa. The trunk can easily reach a height of 3 meters. It is covered with pale green, slightly reddish tinged leaves. They are thick-fleshed and have brown, hard thorns on the edges. The top and bottom of the leaf have thorny spines. The leaf length varies between 80 and 100 centimeters.

  • Flower clusters up to 130 cm high
  • Branched inflorescences
  • Bright scarlet to orange flower color

The thickened juice of the leaves is used as a remedy.

Aloe vera

  • 60 cm high flower stem
  • Tubular flowers
  • Flower color yellow to orange
  • Flowering April to August

The gel inside the leaf is particularly suitable for consumption. It is found in various industrially manufactured foods such as yogurt.

The plants are also known for their medicinal properties. The ingredients of the plants are also used in the cosmetics industry, for example in body lotions and creams. They are also used in everyday objects such as panty liners or cotton swabs.

Plants that Look Like Aloe

There are a few plants that are commonly mistaken for aloe due to their appearance. Among them are:

Agave

The agave is a succulent that looks like aloe. This has a short trunk and lanceolate, thick-fleshed leaves. They become up to 2 meters long and 25 centimeters wide. Their edges also have thorns. In contrast to aloe, the juice of the agave is poisonous and irritates the skin. If agave is confused with aloe, it can have unpleasant consequences. Both types of plants actually look alike.

Aloe vs Agave

If you compare both plants, you will immediately discover the differences:

  • The aloe leaf contains a thick gel, whereas the agave has fibers.
  • The leaves of the aloe grow visibly from the center of the plant, the new agave leaves grow in the outer area under older specimens.
  • A three-year-old aloe flowers twice a year, with the flowers growing sideways. The agave takes years to bloom.
  • The aloe does not tolerate cold and is cultivated as an indoor plant. The agave can withstand temperatures down to -20 degrees.
  • The juice of the aloe leaves contains substances that care for the skin and can even be used internally. A sweetener is made from agave juice, as is the Mexican national drink “pulque”. Sisal is made from its fibers. The juice in the leaves contains toxins and shouldn't get on the skin or in wounds.

Cacti

Although aloes and cacti are not botanically related, they have a lot in common. Both belong to the group of succulents, have thorns and, due to their well-developed water storage organs, are able to survive for a long time without water.

The aloes are a separate genus from the family of grass tree plants (Xanthorrhoeaceae) with a total of around 500 species. The cactus plants form their own family with over 100 genera and between 1500 and 1800 species. The cacti belong to the so-called stem succulents, i.e. they store water in their sprouts. The aloes, on the other hand, use their leaves as water storage organs, they are leaf succulents.

The gel contained in the leaves of aloe vera is valued for its skin-caring and regenerating ingredients. While the wild aloe species grow in the deserts and rocky regions of Africa and on the offshore islands, the areas under cultivation for extracting the gel from aloe vera can be found all over the world. The wild cacti occur naturally only on the American continent.

Aloes and cacti have even more in common:

  • like all succulents they like it warm, bright and dry,
  • they prefer sunny locations ,
  • do not like excessive moisture and
  • produce beautiful flowers under good conditions,
  • the propagation is performed at both succulents by cuttings.
