Here in Texas we have a Dearth July until probably October. With that said I think all I can say is maybe a few trees in bloom and wild sunflowers. I suspect that non native species of plants/trees from stores that have been planted and watered by someone perhaps. Never know really what it is, but it's baffling non the less anything survives in Summer heat when everything turns brown. Flameleaf Sumac I have seen early spring blooms as well as early summer blooms different years. Odd that tree does that.
