Cactus Green

Cactus greens, purples, yellows...

Of course there are lots of cacti growing in the Chihuanhuan Desert of Big Bend NP. I was surprised at the colors of the plant and at the number of different species, more than in any other park. On top of that, the various species of prickly pear cacti hybridize with each other, so you sometimes can't tell at which species you are looking. So, in general, I have identified the following photos with my best guesses.

Cactus grow every where, where it can get a foothold. It needs some soil and some moisture, and it doesn't have to be very much.

None of these photos show the cactus in bloom. When we arrived in Big Bend NP, it was too early but near the end of our 2 week stay, some cacti were blooming. See next blog.
