We all know aloe plants for their majestic looking leaves and their extensive health benefits but not so much about how many types of aloe plants are there. Native to North Africa, there are at least 250 species of aloe plants out there.
Whatever the reason is behind your fascination for aloe plants, in this post, we shall cover not just the most common types of aloe but also some notable FAQs about the plant, benefits, and more so, read on.
How do I identify my Aloe plant?
Aloe plants are often mistaken with hawthorn, gasteria and agave plants. To easily identify aloe plants, you have to look for the fleshiness and shape of their leaves. This is what sets them apart from its lookalikes.
Aloe leaves are typically triangular in shape and are extra fleshy. Compared to agave and hawthorn, aloes are smaller (although you will find later that there are tall aloes).
Another striking identifier for aloe plants would be their spikes that could range from soft to the touch to wound inducing sharpness. Finally, you can confirm that your plant is an aloe and not an agave by doing the snap test.
If you break the leaf of the aloe, you would see a gush of sticky substance coming from it. This is the substance extracted for herbal supplements, cosmetics, shampoos, and soaps. Agaves do not have this gel.
