Ok #plantID folks, is this #horseweed, tarragon, or something else? Apparently horseweed kind of tastes like tarragon, so even if I were willing to eat it, that may not help. https://foragingguru.com/erigeron-canadensis/ PlantNet isn't giving me a probability over 50% for either, but I'm leaning towards horseweed since it's growing in a crack in the sidewalk. iNaturalist seems to favor horseweed.

Web searches yield no results for distinguishing the two plants. Am I the only idiot who can't tell the difference?

@skyfaller Does tarragon have fuzzy stems? I have tarragon at home, but I'm not there to check.
@ryanroat It's possible that some varieties of tarragon have fuzzy stems and some don't? That's what I see in pictures from PlantNet. Wikipedia neglects to describe the stem.
@skyfaller that's a thick and tall plant. I'm pretty sure that taragon is delicate by comparison. and has more of a mounding habit. I think you've got a weed.

@acm_redfox PlantNet is 91% sure this is tarragon now, so even though logic and reason rebel against the thought, I find it impossible to dismiss entirely.
