The Cholla cactus is native to the Southwest US and while it looks harmless is actually a ‘jumping’ cactus so don’t get too close to them because they STICK to everything and their quills are sharp! So sharp that they even pierced my heave hiking boots when I stepped on one. I had to remove my boot and pull the quill out of the bottom of my foot – OUCH! Okay so they don’t really ‘jump’ per se but they stick to everything and they do seem to shed so their pods and quills are scattered all over the cactus garden. Despite how prickly (and painful) they are I do like the look of them at sunset. The way the sun bounces off the quills and makes them glow is pretty magical. I stayed out past sunset and had to very carefully (and slowly) navigate myself back to my car – not an easy feat with all the cacti around.
