Echinocactus
- Description
-
Echinocactus is the barrel cactus genus of the Cactaceae family. It is native to Arizona, Texas, and Mexico. The genus is known for its rounded, ball-like shape that may elongate with age. Many cultivars exist with unusual knobby or fasciated growth.
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:
- Ball-like or barrel-like shape
- Clearly defined rows of vertical ribs with long, sharp spines
- Wool-like fuzz at the top of the stem where the flowers emerge
- Funnel-shaped flowers with numerous petals
