Difference between a cactus and a succulent
Why do we confuse them?
Succulents have been a staple in our homes for decades. We appreciate them for their minimalist aesthetic and low maintenance. However, when you're new to the wonderful world of indoor plants, it's common to confuse cacti and succulents. This confusion stems from the fact that all cacti are succulents, but not all succulents are cacti! We'll clear things up in this article and give you tips for caring for these fascinating plants.
Botanical point of order
The term "succulents" is a generic term in horticulture referring to plants that grow naturally in arid and desert areas. These plants withstand these extreme conditions by storing water in their tissues (mainly the leaves, but not only) and through a form of photosynthesis that requires less water. Succulents therefore form a large group that includes several botanical families including Crassulaceae, Euphorbiaceae and... Cactaceae, in other words, cacti!
A succulent is a plant with waterlogged tissues adapted to drought, while a cactus is a succulent that belongs to the Cactaceae family. They have a unique characteristic: the presence of areoles, small buds from which the spines and flowers grow.
How to recognize a cactus?
All succulents share a fleshy morphology, but cacti are distinguished by a few specific features.
- Presence of areoles: these are small pads from which the spines grow. They are exclusive to cacti.
- Lack of true leaves: Most cacti do not have leaves to limit evaporation.
- Thorns: They replace leaves and protect the plant from the sun by providing shade as well as from predators.
Euphorbia are often confused with cacti because these succulents also have thorns. However, they do not grow on areoles, and their latex (sap) is poisonous.
General tips for caring for cacti and succulents
There are obviously differences between species, but all succulents, including cacti, have fairly similar needs.
- Light: Plenty of light, usually full sun.
- Watering: Infrequent! Make sure the soil is completely dry between waterings. It's always best not to water if you're unsure!
- Soil: Well-draining, a premixed cactus and succulent mix is ideal.
The key? Absolutely avoid overwatering, as it is the leading cause of death in cacti and succulents.
