    They are considered a nuisance in our pine barren neighborhood by the Hudson in upstate NY. Do they really close their leaves at night?

      I looked in two Calif floras, and there was no mention of that nighttime behavior. … Apparently there are 8-10 separate species of Robinia (North America and Mexico) so you may or may not have this exact species. Mine is said to have edible flowers but toxic seeds, leaves and bark. People and livestock can die from those parts.
