Burdock. I've got them. Don't bother me but i have a large farm...no way to control them. Nice flower heads that then form burrs that stick to everything... You probably have more than a few, so just keep a look out next year as well if you don't want them. Or just let one grow to enjoy the show...but destroy it before it sends out more of itself.

Phlox?

English sucks. I don't know how people learn it as a secound language. If you don't see the same plant growing in other places nearby it's likly a cultivated plant. If it's growing in the alley and behind the shed it's probably a weed. If it's a voliteer plant from seed of a cultivated plant and growing where it's not welcome that's a weed as well. Then you have wildflowers like Indian Blanket and Blue Bonnet that are nothing but weeds most of the season that happen to have pretty flowers briefly. If they are in the way chop them down. The worst weeds I've dealt with was Trumpet Vine and Bamboo but some folks plant the stuff and water it. Hey,I once smoked grapevine when I was a kid,I wonder if anyone ever tried smoking a Bamboo stalk? LOL

Wow, had no idea they spread that much! Thanks DG...I have since dug up the plant and put it in a large pot a few weeks ago. It was blocking my sprinkler head and killing the grass in front of it. I thought I killed it :o(...the plant went in shock and all the leaves drooped. I removed all the leaves and hoped for the best...within 2 weeks new growths came up from all the areas I removed the leaves from...here it is today. I knew digging it up after Its been in the ground for 2 1/2 years was not a good idea since I really thought it wasn't going to make it anyways...
