Damianita and mealy blue sage.
Claret cup cactus, Echinocereus trilochidiatus.
An unknown yellow iris. This one blooms a little later than the others.
Zepherine drouin in the back corner. The amazing thing about this rose is that it grew from a root that grew through the bottom of a potted cutting growing in this very spot. When I removed the pot I noticed this wiry shoot growing between the limestone path. It grew into this lovely arching rose. No extra water or fertilizer and yet it blooms faithfully every year. It is the same pink as the bush knockout in front of the wall but has one difference. It is extremely fragrant. The mother plant grows in the front courtyard.
Mock orange, Philadelphus coronarius Natchez. My only regret is that I didn't seek out the native one which has a fragrance.
