In July I noticed honeybees were pollinating these bushes in the cemetery. I took photos so I could show them to knowledgeable people to ID them. I asked quite a few people who had no idea what those bushes were. Jim, the volunteer at the cemetery, said at first he thought they were planted, but later he realized the birds must have dropped seeds where the mower couldn’t reach and they just grew without being cut.
I shot some video of the blossoms with the bees getting nectar. If I see the birds eating berries, I’ll get a video on them.
