A year ago you identified "kalanchoe daigramontaniana" for me - I may not have the spelling exactly correct. Can you identify either or both of the attached images - one is a shrub, the other just a flowering plant along the driveway under the shadow of, I think, a prickly pear cactus. Both are in the Phoenix area, and the time of year is early April.
And the cactus is indeed an Opuntia, but without seeing flowers/fruits it will be difficult to determine which one.
