Day 7 of the "30 in 30" painting challenge

I'm one of those people that think weeds are pretty.
Last year, when I got my new camera, I think I took pictures of every weed we had in our yard, while playing with the new zoom. I was like a kid with a new toy.

I'm not sure what this weed is called, so If you happen to know, would you mind letting me know in the comment section. I'd appreciate it.
