The red blooms are fairy dusters. Up close they look like old fashioned dusters. When we volunteered at the wildlife refuge there was a fairy duster bush by the front entrance. The desert tortoise had his home up by the entrance as well. He loved being fed the fairy duster blooms. They were like candy to him. The biologist warned us all not to feed him too many or it would make him sick. The only time the turtle moved with any speed was when you tempted him with a fairy duster.
The orange and yellow flowers are the shape of trumpets. The hummingbirds can reach in them and get the nectar. Bees also fly down into them. Our friends have their RV on a rental lot like ours only theirs has these beautiful flowering bushes. We have an ocotillo bush that might get green leaves on it and red flowers on the top once while we are here. We also have small palm trees but they don't flower. The bushes are pretty in bloom but they also provide cover for mice and rats and other critters so we would just as soon not have any on our lot. We just enjoy everyone else's.
