Teddy Bear

 Teddy Bear Chollas are a plant of the Sonoran Desert, growing in exposed areas with full sun. They are completely covered by thick, gold-colored spines that obscure the green skin and give a cute, fuzzy appearance.  But WATCH OUT and don't get close.  
Both spines and stem segments are easily detached, adhering to anything that moves, and can be difficult to removing owing to tiny reverse barbs.
