That's why I hated that cactus! Those little hairs are so irritating. You can never seem to find them all if you happen to accidentally touch that cactus.
Those lil hairs are actually called glochids. Those are so annoying. I sometimes prefer being poked by the bigger thorns. At least there easier to find and remove granted they sometimes hurt and draw blood.
Ill actually have like 3-4 of these plants growing in my garden. One is from my grandpa's original cactus. When I see it, it brings back old memories of my grandpa. Another is from my Great Uncle from my grandma's side. Sadly he is dying from cancer. The third I jacked from someones yard lol. A quick swipe with my pocket knife and I had myself a new cactus. The fourth is one that turns purple with the bright sun. I dont have it but thinking of buying one. Of course these will all be kept trimmed since they all get HUGE.
My garden plants will consist of mostly Agaves and Aloes. I am thinking of growin some milkweed to attract some monarch and queen butterflies.
