I thought I had the matching flowers for this plant in my neighbourhood, but not so (I'm upset that it seems to be the same planter, but the leaves are different), and I don't know where that plant has gone, and I don't know what these flowers looked like. The fruits seem to be turning purple or black. Leaves are cherry-laurel or camellia looking, but they are opposite. Of course I didn't think to measure the fruits, but I think they were around 1.5 cm long.
Thank you, David. That works. I found one Floridata photo that looks very similar, at https://images.floridata.com/gallery/Ligustrum_japonicum_frt800.jpg. It doesn't expand from the page it's on: Floridata. I thought those persistent pistils might be characteristic, but it seems they are not all that persistent - I see a few, but only a few, in the Floridata photo. I forgot about privet. It's not exactly rare around here.
