What are the best varieties of Barrel Cactus to grow?

The Barrel Cactus is one of the most popular plants that you will see in a lot of backyards in the southwestern US and Mexico. The cactus is a very common part of rock gardens, desert landscapes, and even indoors. However, since there are a number of different varieties of Barrel Cactus, it can get difficult for people to decide which is the best kind to grow. This is the main reason why, here in the guide, we will share with you the top varieties of the Barrel Cactus that you can grow. 

1. Golden Barrel Cactus

   
   

People love the Golden Barrel Cactus, or "golden ball cactus," for a reason. Its bright yellow spines and round shape just stand out, especially in a desert garden. This cactus comes from central Mexico and can get pretty big, up to 3 feet tall and just as wide. Sometimes it stays by itself, but as it grows, it might send out little "pups" around the base and form a cluster. 

2. Mexican Fire Barrel Cactus
   

This one’s a real eye-catcher. The Mexican Fire Barrel Cactus, true to its name, grows wild in Mexico. Its bold red spines look like flames against a deep green body. These cacti usually stay on the smaller side, about 3 feet tall. As they mature, they often grow offsets, or "pups," at the base.

3. Blue Barrel Cactus 
   

If you want something with a little more drama, check out the Blue Barrel Cactus. It brings a cool bluish-green skin and long spines that range from yellow to reddish. It’s another Mexican native and tops out at about 2 feet in both height and width. This cactus likes to produce a bunch of offsets, so it ends up looking like a cluster of heads as it ages.

4. Southwest Barrel Cactus
   

You’ll spot the Southwest Barrel Cactus all over the deserts in the Southwestern US. Those big, reddish-brown spines make it easy to recognize, and it can grow surprisingly tall, sometimes five or six feet, although it takes its sweet time. This barrel cactus usually keeps to itself instead of forming clusters.
