I found this growing alongside the road, with a few other flowers that I can't put a name to. These are growing in North Central Idaho. The one I photographed was about 2 feet fall, and the flower head was about 4 or 5 inches across. They were growing at about 2,300 feet in elevation, if that helps any!

Any suggestions would be appreciated!

Pretty! Looks like Wild Parsnip (Pastinaca sativa) which is considered invasive in some areas: Parsnips (Pastinaca sativa)

Thanks Lin! It's an exact match, except for the foliage! That is what had me stumped. I'll have to see if there are other varieties of that plant, but haven't had time to check yet. I thought it was very pretty, and very odd looking! We do have wild parsnip in the area that have the same foliage as in the pictures in the links, but this one doesn't seem to be the same plant.

Other possibilities but I don't know if they grow in Idaho, LOL:

Golden Alexanders (Zizia aurea)

Land Cress (Barbarea verna)

It isn't either of those, but I like them!

The second picture in the bottom row has a close up of the foliage, on the plant in the front. The rest of the foliage in the background wasn't the same plant. I didn't see any other foliage on the plant, and saw the same thing on several of the plants. That is what has me stumped.

How about Nineleaf Biscuitroot (Lomatium triternatum?)

That just HAS to be it!!!! The foliage is an exact match!

You are good! Thanks so much!

You are very welcome! I was having trouble trying to see the foliage in some of the photo's when googling ... glad that last one was a match!

I added the photos to the database and also added the plant information. I'm thrilled to know that it's not poisonous, and won't hurt the dogs! It's actually edible, at least for people!
