I've spotted this plant growing in my herb spiral for years, but never knew what it was. This year it made berries that look very nightshade like. Any idea what this plant is? Is it poisonous like deadly nightshade?
What color are the berries when ripe? If black, probably deadly nightshade or belladona. If red, likely bitter nightshade. Leaves and flowers look much the same. Both are perennials that spread by rhizomes.
I have a nightshade relative in my garden with edible black berries called schwarzenberen. It's an annual but the berries look a lot like deadly nightshade. I just noticed that. :) A bunch of other plants we use regularly are also in the nightshade family.
Zone 5b/6a, alkaline soil, 12 inches of water per year. For now the goal is a water independent urban homestead with edible landscaping and food forest.
