Palo Verde in Bloom, Tucson, Arizona.
D850 with 105mm f/2.5 AI (chipped) at f/2.5, 1/500 sec, ISO 64.
Another photo from the neighborhood a few days ago. Palo Verde trees have interesting green bark and bloom vibrant yellow. Some years the blooms are particularly impressive. Unfortunately it was very windy today, so I don't think I will find much left this year in that regard.
