Is This Poison Hemlock? #868573
Asked May 15, 2024, 2:34 PM EDT
We found a plant growing in our garden box, and we're trying to identify it. Our various apps and Siri have been all over the place, from poison hemlock to knotted hedgeparsley. I don't personally observe the purple stem coloration I'd expect in hemlock, but the leaves do have a darker green color and some sheen to them. Thanks in advance for any help in identification!

Hi Scott,
Unfortunately I am unable to open .heic files from Macs/iPhones. Can you change the format to .jpg or .png?
Thanks!

Poison hemlock has hollow stems - does this? You are correct that the purple/red streaking is a good identification characteristic and these do not have it. I think we can rule out poison hemlock.
It's definitely something in the carrot (Apiaceae) family. By "garden" do you mean a vegetable garden or a landscape bed?
Many of the plants in the carrot family are biennial, so it's possible that something like parsley, carrots, parsnips, etc. were left and reseeded. Or it's something like Queen Anne's lace ("wild carrot").
Really the only way we could positively ID it is if you let it bloom.
