The good thing about being a neglectful gardener is, suddenly you discover a robust new weed right in your own yard. (Actually, I guess not everyone would consider that a good thing.) I had been waiting for this to bloom, but as it turns out, for pilewort, this is full bloom. Also called fireweed because it likes disturbed areas, especially where there’s been a fire. Animals avoid eating it because the foliage is bitter and bad-smelling. Composite family. Native annual.
