Although these flowers are not exclusive to the desert they do well here and provide a change from cactus. These bushes are in my yard or near my house. The one above is Oleander. It is poisonous, but very hardy. It's next to the wall of my front enclosed patio.
The middle one is red Honeysuckle and is by the mail box.
The last one is Texas Ranger and I have three plants in my back yard.
(If only I could learn how to compose the photos and the text without losing a photo I would enjoy this project more.)
