Echinocactus
Common Name(s):
- Description
-
Barrel cacti are in the Cactaceae family and are native to Arizona, Texas, and Mexico. There are 6 spieces in this family and many varieties. The genus is known for its rounded, ball-like shape that may elongate with age. Many cultivars exist with unusual knobby or fasciated growth and all have many spines. They vary greatly in size and are much smaller when grown in a pot. The popular Golden Barrel Cactus can grow up to 35 inches across in its native habitat. They will produce offsets with age.
These plants grow best in full sun, but they can tolerate a little bit of shade. They prefer dry soil and low humidity and need a good cactus mix with extra grit for drainage. It can be easily grown as a houseplant in a container, and it is tolerant to a wide array of conditions.
Quick ID:
