i think thats lambs quarters

if its a mock orange.. and if its an unnamed variety ... which is obviously aggressive.. as many of the unnamed weed like ones are ... its about 10 feet too close to the house.. and probably will never smell i have two of this type.. and they are about 10 feet tall..; and 12 feet wide ... and have a bazillion quarter sized flowers and barely a scent... i have other less aggressive ones.. that have silver dollar sized flowers.. that you can smell from a hundred feet away ... its form.. makes it look like a recent planting.. some flowering shrubs can take a few year.. to get their act together.. and bloom with vigor ... and that SMALL brick planter area is not going to work .... but it never will if it keep getting cut back ... and if you have to do that.. and dont get the smell.. i dont know why he would want this rather ugly bush outside that glorious window .. frankly.. this thing needs go go out ont eh property line somewhere.. and be replaced with something smaller .... get a pic of the whole area... and visit the perennial or shrub forum.. for suggestions.... ken ps: it wont bloom this fall ... its a late spring bloomer

I missed that you had come back with a reply, Coach! It sounds like you have some species of Asclepias! One of the common names is butterfly weed, and people pay money for the stuff you're trying to get rid of! Like dandelions, the seeds "float" in the air, and my guess is that some neighbor pretty close has one/some they're cultivating to attract butterflies! The most common species is A. incarnata--but I really have no way to know if that's the species that's showing up in your yard or not. Some info at the link below if you're interested in more! In terms of getting rid of it, I recommend Weed-B-Gon. You can use that in the grass--it kills only broad leaf plants, and you can use it where there is no grass too. From my experience it works better than Roundup, and it's what I use anywhere I need an herbicide these days--works quite well at getting rid of cottonwood and aspen suckers in the grass! As far as I know all, or at least most, milkweeds have taproots, so the sooner you get rid of them the easier it will be. If you decide to try to pull them, you'll need to get all of the root out or they'll come back from anything you leave behind! If you have a place where you want to grow some to attract butterflies (it's also a host plant for the caterpillars), you can just deadhead the flowers before any seeds form to help keep them from "filling up your yard!" Can't help with "the neighbor" if I'm right that that's where the seeds are coming from! Skybird P.S. The "plant" you were getting into as a kid was most likely dandelions! Here is a link that might be useful: Asclepias incarnata

I can't see it clearly, maybe violets or Ranunculus, that were not killed before using this bed (below the level of removed material,) or seedlings from seeds in the mulch (or seeds that were residing in the soil already, below the level of what was removed.)
