So many options that aren't prone to powdery mildew and some benefit wildlife (bees, birds, or butterflies). Carolina Buckthorn, Mexican Buckeye, Texas Persimmon (has bark much like a crepe myrtle), Arroyo Sweetwood, Mexican redbud, Red Buckeye, Eve's Necklace, Goldenball Leadtree, Huisache, Kidneywood, Desert Willow, Cherry Laurel, or Anacacho Orchid.
