Aloe plants are known for their imposing leaf rosettes. There are nearly 500 different types of these succulents. These include both edible and poisonous varieties. The most famous representative among the countless varieties is undisputedly the edible aloe vera.
In order to recognize and differentiate the plants correctly, we have listed some known and lesser-known types of aloe plants as a small guide.

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.

- Bright red to scarlet flower color

Why, When, and How to Prune Aloe Plants
Plants that Look Like Aloe
There are a few plants that are commonly mistaken for aloe due to their appearance. Among them are:
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.
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.
