There are over two hundred types of cactus, and they can be found in the tropics and temperate regions around the world in areas like the United States, Mexico, South America, Africa, and Australia. Cacti are among the most fascinating plants you can grow in your home or yard.
Cactus plants are an incredibly diverse group of plants that come in many different shapes, sizes, and colors. The easiest way to think about them is by their classifications, which include tree cacti, flower cacti, and regular cacti.
Finding the right types of cactus plants to grow can be difficult if you don’t know what you’re looking for. Some types of cactus plants are better suited to low light, while others love to bask in the sunlight.
Some are perfect as ornamental houseplants, while others need desert conditions to thrive. In order to find the right types of cactus plants, here is a list of the 25 best types of cactus with pictures and descriptions of their ideal growing conditions so you can select the right plant for your indoor or outdoor garden!
Types of cactus
Christmas cactus (Schlumbergera)

The flowers are white or pink and bloom in the spring. The fairy castle cactus produces large orange fruits that are edible but have a sour taste. They’re also called pitaya pear because they resemble pears and have red skin.

Make sure you let the cut end dry out before planting it in the soil. Keep it in bright light, water occasionally, and fertilize once or twice a year. When winter comes around, store your plants outside or give them enough light indoors so they don’t get too stressed out.
The barrel cactus is one of the most common types of cacti. It is also one of the easiest to care for. Barrel cacti are native to the deserts of the southwestern United States and Mexico.
These cacti can grow to be up to 20 feet tall and 12 feet wide. Barrel cacti are easily recognizable by their round, cylindrical shape. They have a ring of white spines around the top which is called a crown.

Glow-in-the-dark cactus (Euphorbia tirucalli): Euphorbia tirucalli is also known as the glow-in-the-dark plant because its body will start glowing when there’s enough sunlight around.

The flower only lasts one day but during this time they can be pollinated by hand or insects. Moon cacti don’t need much water and are able to survive droughts fairly well.
There are other types of cactus out there that don’t need nearly as much attention as the moon cactus does, so keep this in mind when considering this type of plant for your home.

If the environment is too humid or if the soil has been watered too much, it’s a good idea to place some stones in the potting mix. That way when the bunny ear starts to wilt, you know that it needs water instead of worrying about whether your plant has wilted due to being overwatered.
Feather cactus (Mammillaria plumosa)

The blue columnar cactus needs well-drained soil and its flowers are pollinated by hummingbirds. When watered, the roots will grow out from the ground quickly, so the plant should be placed in a location where there is no traffic.
Easter cactus (Schlumbergera gaertneri)

These plants grow rapidly in good conditions, but can also be grown from seed if you want more control over the appearance of your plant. It’s not as cold-hardy as some other types of cacti, so it should only be planted outdoors during the summer months in zones 9 and 10.

The flowers are pink or red and bloom in the spring. Powder puff cacti are easy to care for and make great houseplants. They do not need too much light but require protection from frost.
These plants need less water than other types of cactus due to their round shape and short spines. They can be propagated by dividing the plant after blooming into many smaller plants.
During the summer months, they need to be watered more often because of increased sunlight exposure. Plant these cacti in well-drained soil as they cannot tolerate sitting in standing water for long periods of time.
Balloon cactus (Notocactus magnificus)

Be careful when handling these plants as they have sharp spines on their leaves that may poke holes in your skin if you don’t handle them carefully enough. When choosing potting medium, remember that this plant has a shallow root system so use something lightweight such as sand.
To avoid getting poked by the sharp leaves, wear gloves while planting and then remove them afterwards. These plants thrive best in warmer climates without frost but will tolerate cooler temps (down to 20 degrees Fahrenheit) without any problems.
Strawberry cactus (Mammillaria dioica, California fishhook cactus)
