There are so many gorgeous weeds on our homestead!
The first one I found turned out to be a variety of wild mustard.
The second hairy vetch.
I found this one growing tall and bushy in the pasture.
The taproot is fibrous
The stems are so thick
The flowers attract many bees
The tiny white flowers
The sweet smell of grass
The bushy and ferny green leaves
They tickle and prickle
They grow tall and wide
They swish and they sway in the breeze
What is it?

Looks like Queen Anne’s Lace. Look for the purple flower in the middle when they bloom. http://www.eattheweeds.com/daucus-carota-pusillus-edible-wild-carrots-2/
Or it could be poison hemlock. If it doesn’t have the purple centers. http://plants.usda.gov/core/profile?symbol=coma2
Here’s a better link to Queen Anne’s maybe http://plants.usda.gov/core/profile?symbol=DACA6
I was thinking Queen Anne’s Lace too. I just didn’t know if it grew that tall.
It grows pretty tall. 🙂 just check for people flowers. And the leaf lobes are more fine on the QAL than the hemlock. Hemlock leaves are more fern like. Check out the photos. 🙂
