This striking plant is growing in our fence line. Can anyone explain it to me? At first, I thought it might be a rogue tomato, but now I'm wondering if it more like a pepper. It is near a neighbor's former garden. Do you think this is something native, or something escaped from the garden? You can see the leaf just above the wire on the right side of the photo.
See the upside down T? That is the stem of this plant. Any ideas ? !
UPDATE: Thanks to Greenmantle (all the way from the UK), I have an answer - Bittersweet Nightshade (Solanum dulcamara). It isn't as poisonous as some of the nightshade family, but still poisonous. It isn't on the local noxious weed list (just a weed of concern). See this link for the scoop from King County, Washington.
I think I'll leave it on my "to monitor" list, at least for another season. While many varieties are welcome in the fence row (a mini hedgerow), rampant, bully vines are not welcome! We will see...
