Frilly leaves and black seeds

Posted by Ronninator utah (My Page) on

This plant is crowding my blackberries. At this point in the season, it is everywhere in the planter box and I don't know how to get rid of it. I thought an ID might help.
When it gets big enough, it produces v-shaped branches with black cone-shaped seeds. I didn't see any flowers.

I appreciate any tips. One thing: I have a lot of bird seed in my yard, so if it's not a weed, it would be that.

Artemisia vulgaris/Mugwort, I think.

RE: Frilly leaves and black seeds

Hi there
Black seeds are not typicall for Artemisia.

The mentioning of bird seed points to Ambrosia, hitching a ride in the bird seeds.
Its pollen is difficult for hay fever suffererers,
leaves could irritate the skin.

I would digg it up asap, trying to get the main root.

And perhaps look for different bird seed

Here is a link that might be useful: Ambrosia artemisifolia
