As you may have guessed from the title, we will be discussing the different types of cactus Plant for your home in this blog, but before we get to the best, let’s get the basics out of the way and understand what is cacti?
Cacti, known by its family name Cactaceae, is a very popular and common desert plant. The word “cactus” originates in Latin from the Greek word kàktos. The word was first used by Theophrastus to describe a plant with spines that have not been identified as of yet.
Cacti mostly live in humid conditions and habitats that are subjected to at least one drought. Many cacti live in dry regions like the Atacama desert, the driest point on Earth. They have thus acquired the ability to survive without water for a longer period of time.
Are All Cacti Succulents?
All cacti are succulents which means that they store water in their thick and fleshy parts, mostly in the stem. Cacti and succulents are interchangeable terms but they are not the same as all succulents are not cacti. The spines on the cactus are modified leaves that prevent water loss and assist in water retention. The areoles are the identifying factor of cacti. These are small bumps out which develop the spines. Areoles also give rise to multi-petaled and tubular flowers. Many succulents do not possess areoles which is why they are a different family altogether.
Cacti are normally thought of as desert plants but they can thrive in home environments too and can make a pretty cute decor. Here are some cacti that will make your home pop with some green and cuteness. They have been differentiated into indoor and outdoor cacti and have been named along with their scientific names just for your reference.
