We live on the west side of Orcas Island, and I found this growing at the edge of our garden (we basically stopped tending the garden, after the 8th deer incursion, so the edge of the garden is a weedy mix). I have no idea what this is.
Don It makes me think of the Nightshade family. There are lots of poisonous members in the nightshade family. Avoid eating it.
Nightshade (Solanum species). My guess is Solanum nigrum - do a google search for images, and see what you think. It’s non-native, and weedy.
