What is this (probably) weed with nice fern-like foliage?

A detail from the top right of the second photo, where the stem of a plant in the background that appears to be the same species is visible:

If crushed, the leaves exude scent of medium strength that resembles cut grass scent. It wasn't an unusual scent. It is not poisonous to inhale the fragrance (I am alive and feeling well so far).

The zone is 8a, photos taken in mid-March. The winter was mild.


I found two similar plants using internet searches, which I hope my plant is NOT:

    I think it is not a weed nor a fern. But if you have doubt about ferns, you should take a photo of the bottom part of the leaves, and the stem (or usually lack of it) – Giacomo Catenazzi Mar 15 at 12:47
  • Ok, it looks a little bit like fern, especially from the distance. :) I'll provide any requested or suggested photo, but it may be with several days delay. Thanks for the hint @Giacomo . I do not mind having this plant, actually it gives me nice "jungle" aestetics feeling. But what if it is invasive, or drain energy and water from the soil much better than other surrounding plants, that I planted ladt year? This plant wasn't there last year. If it is a native wildflower, I would definitely like to keep it. But I don't know that. – VividD Mar 15 at 12:53

    Vivid, does it have an odor if you crush a leaf? – Jurp Mar 15 at 13:33

    I don't know. I can't check right now, perhaps in next couple of days. But what if it poisonous? If I don't appear on this site for a week, it is poisonous if crushed and smelled. @Jurp – VividD Mar 15 at 13:36
  • Looks a little different than the wild hemlock we have round here. Does it grow low to the ground through winter, like hemlock? From pix, you may not even have winter. Those long thick stems look decidedly not-fernlike. – Wayfaring Stranger Mar 15 at 15:54

On first thought it seems like cow parsley (Anthriscus sylvestris), but after reading stormy's comment about Poison Hemlock it is more likely to be that. Be careful not to eat it before you are absolutely sure about if it is poisonous or not.

  • This is very helpful. I hope the stem color will tell the species. But these are very young plants, perhaps stem coloration is not yet developed. – VividD Mar 15 at 15:38
  • I updated the question with new photos. Some purple spots on stems worry me. – VividD Mar 17 at 20:02
  • It might be Poison Hemlock instead, check the link in stormy's comments about Poison Hemlock. Don't eat it, it seems Socrates was killed by it!! – benn Mar 18 at 7:31
