No, I have not noticed any significant impact from A. absinthium, although I will certainly keep my eye out for anything unusual. This will be its 3rd year in my herb garden, with close companions bronze fennel (Foeniculum vulgare), mugwort (A. lactiflora), blue vervain (Verbena hastata), gas plant (Dictamnus albus), with random garlic here and there. I do recall the dictamnus and mugwort having some problems late in the season last year, but it may have been simply water stress. I will monitor this more closely this season. All of these herbs are very hardy, perhaps the negative impact would be more pronounced on more tender plants.
