Not something you would think to find in the desert. It looks like the flowers on my wife's orchids.
I was able to find a Prickly Pear in bloom.
This barrel cactus is of the same species as one I have at home and about the same size. This is about as big as the blossoms get and are always in a circular ring on top. I once saw a barrel cactus this size for sale in a nursery for over $200. Main reason is that it takes a lot of years to become this big. I've had mine for around 30 years, give or take.
The Hedgehog cactus has brilliant strawberry or violet colored blossoms but I didn't find any in bloom.
Mine at home is about ready to open up.
A few wildflowers for your viewing pleasure.
