We have these lovely cacti in our yard. I haven't found out the name of the one with the orange flowers. The one in the bottom picture is called "old man on the mountain". It gets all these fine white hairs covering it. So far they are small and out of the way so we won't get poked or stabbed accidently. As we walk around the neighborhood we have seen so many different varieties of cacti. You just can't believe there are so many different kinds and each kind has a different color and shape bloom.
Since this is Tucson and we are next to Saguaro National Park there are a lot of saguaro cactus in our neighborhood. Those are the ones with the arms. They are finally starting to get buds on them and will start blooming soon. A gal from Saguaro National Park came and gave a talk about the park at our rec center. It was very interesting to learn about all the wildlife in the area as well as learning more about the cactus.
