Who would have known that desert plants could be a great add on to your living space. What’s even nicer is when they start blooming, the combination of their flowers, hairs and spines gives off good energy in the room. Many people don’t see cacti as beautiful plants, but they certainly can hold their own against even the most vibrant of flowers.

Cacti are unique in their own way and there are plenty of species you can choose from. What makes them attractive to many plant enthusiasts is that they require minimum maintenance and are easy to take care of. Unlike some other indoor plants, cacti are adept at surviving in dry environments and handling neglect. With well draining soil, and a bit of care, cacti are easy to grow indoors. Below are some of the best indoor cactus varieties to choose from.

Some varieties can grow up to 8 feet tall and grow thorns in-between its leaves. This is technically a succulent, but most people will think it’s a cactus on first inspection.
