Sumac has just started to bloom, as well as Goldenrod. My bees were carrying in loads of dark gold pollen. I thought it was Goldenrod until I passed by a large Sumac this morning. The bees were wrapping it up, while the Goldenrod right next to it was devoid of bee activity. The bees all had their baskets full of dark gold pollen. Still haven't found any Pepperbush on my place.
