Echinocereus viridiflorus var canus. The very rare cactus lives only in the Big Bend Ranch State Park and only on a few hills inside the Solitario, a circular geological formation famous among geologist around the world.
Its white spines and bright green flowers make it worth the long hike required to see it.

I do consider all the concepts you have offered in
your post. They are really convincing and can definitely work.
Still, the posts are very short for novices. Could
you please lengthen them a bit from subsequent
time? Thanks for the post.
So beautiful. Thank you.
