Echinocereus are delightful little cacti that generally only reach around 12 inches in height. They are very easy to care for as long as you don’t overwater them.

Apart from having quite attractive cylindrical stems with multiple spines, these cacti produce the most gorgeous large flowers in spring. These blooms come in a variety of different colors and are quite amazing to see. Many Echinocereus cacti also produce edible fruits, however, you have to remove the spines first. 

There are over 130 species of Echinocereus cacti varieties with some of them being subspecies and others, cultivars. We’re going to look at the more common ones that cacti lovers grow.

Echinocereus coccineus (Scarlet hedgehog cactus)

If you live in a climate where you can grow this cactus outside, you’ll discover that it will produce a large colony of stems over a long period of time. This is a clumping cactus and thus, produces offsets readily, even when grown in a pot.
