Don’t be fooled by the common name teddy bear cholla – this cacti is far from cuddly. On the contrary, it is hands-down one of the best choices as a security or barrier plant. It can grow from three to six feet high, and three feet wide. Its canopy coverage can be up to seven square feet.
Older spines remain on the trunk, turning dark brown or black. They contrast with new top growth that is bright, light yellow, and deadly to the touch. The segmented stems break off easily, attaching themselves to passersby or pets, so avoid planting near walkways.
They require very little water, and typically exist on an annual rainfall of four inches or more. It is native to U.S. Southwest and northern New Mexico.
