Those are (were) Simpson Stopper berries, a pleasant native edible. I set a little plate of them down on the mulch to take a photo… and suddenly was joined by a ravenous one-year-old… so I kept taking pictures.
Last year I planted three of these bushes in my yard. This year, they each bore a little handful of fruit. Though they’re usually used as an ornamental hedge plant, the berries are pleasantly sweet with a bitter grapefruit aftertaste that I quite enjoy.
In a few years when the bushes mature, I’m totally making jam out of them.
Unless a baby gets them all first.
