Yes, pretty much anything that grows in
the Arizona desert has barbs or spines
on it! I tried to get a shot of one in
bloom when the wind was blowing. Yours
turned out really good, Dean!
Thanks Larry, it was the guy I was with who mentioned the blossoms to me. I really enjoyed learning about the Sonoran desert, so different in plant species from the Mojave desert that I pretty much grew up in.
