Name that weed!

So I chopped down about 50 of these freakish plants yesterday that grew on the side of my house it what seems like a total of about 2 months. Really weird things. Grows to like 7-8ft tall. No flowers. Cut down a jungle of them yesterday. Outer stalk is like celery/fiberous, inner part is like a white silky weird substance. I've tried figuring out what they are, but have no clue. I'm spraying the whole side of the house and every other weed I can find this weekend with white vinegar.

Looks like Bamboo and its a pain in the ass.

Bamboo?

That's the site I've been using to identify it. Bamboo doesn't seem to have stalks/leaves like this; and yes, it's a TOTAL pain in the ass. It literally jungled up the side of the house.

The big three prong dinosaur foot looking leaf is what sprouts off it. Doesn't seem to be toxic.

Looks like some variety of elderberry... The three pointed leaf is wrong, but everything else matches.

I've got them too and I just pull them. It's a week plain and simple, not any version of a tree.

I let one grow last year just to see what it would do and it stops at about 6' for me. It dies completely out in the winter and does not come back.

That's all I can tell you.

Yeah, definitely not bamboo. That is a giant grass, so the leaves are not divided, and the veins are all parallel.

I grew up in Toledo and they were everywhere. I am sorry, I do not know the name, but if it is what I am thinking, It grows very fast and if not tended to quickly, it will turn into a tree. Literally, a tree within a year or two.

I'm not sure of the correct name, but growing up, we called it milkweed.

No milkweed is totally different. There are no pods on this one and it doesn't leak milk like the milkweed plant.

Giant ragweed?

I may have to eat some.

Now that is very interesting.

I wonder if Giant Ragweed has the same allergy producing pollens as the normal ragweed? None of these I've seen have produced a flower like the ragweed, which we have too.

Now if I could only get rid of my Fallopia japonica. THAT E36 M3 is straight from satan.

Yep that's Ragweed alright. I spent many summers taking fields of it down with a bushhog. If you don't take care of it, they can get to be about 20 feet tall.

one of the few plants I am still allergic too... you can keep it
