Buttonbush, Aransas National Wildlife Refuge, Texas July 2019

Apparently, Buttonbush (Cephalanthus occidentalis) is a wildlife favorite: deer browse on it, birds love the fruit, while bees, butterflies, and hummingbirds savor the nectar. Swallowtail butterflies were all over the flowers of this marsh shrub the other day, though sadly, they refused to pose for me.
