Bumblebee on Partridge Pea

This partridge pea was folding up its blooms and leaves to close shop for the night but this oddly gray bumblebee wasn’t budging from what I’m hoping is a deep nap. A couple others I chaos sowed grew as well but are runtier and sport maybe a couple flowers, this one however has dozens and dozens of blooms everywhere and there’s always some sort of buzz around it.
