While biking today I noticed a small patch of plants along Coal Creek Parkway that I haven’t seen before. I don’t know if they are native to WA. Does anyone recognize the plant in the photos? It was beginning to flower and looks to be in the Apiaceae family. The fine hairs on the stems are unusual and perhaps distinctive. It lacked purple spots on the stem so not poison hemlock. The leaves are similar but more intricate than cow parsley.

Maybe burr chervil (Anthriscus caucalis)? If so, not native. Likely invasive (aren't they always?) https://burkeherbarium.org/imagecollection/taxon.php?Taxon=Anthriscus%20caucalis
