Don't recognize the first but the second is a Japanese anemone; third is a campanula or bellflower, probably Campanula rapunculoides. Next is an allium seed head as you thought, followed by hardy plumbago, Ceratostigma plumbaginoides. And the last does look like garlic chives - you should be able to tell from the smell of the foliage :-))

btw, I'd cut back all the bellfower foliage and get rid of it. That's a pretty good case of powdery mildew :-)

Google some pics, Misty, but if that one does turn out to be Campanula rapunculoides I recommend loosing it--FAST! That's one of the VERY invasive Campanulas! Check out the link--rhizomes 8" deep! OMG!

I second Skybird - those campanula (I always called them harebells) are Thugs with a capital T! Once they are in your garden they will never be gone, and as you see, they are susceptible to mildew which makes them ugly later in the season.

Thanks so much for the help! I'm going to pass this along to her.

Yikes! I do believe you are right that the one with the mildew is creeping bellflower! Glad I didn't take any of that!! This neighbor inherited all of this from previous owner, and from the looks of the yard, it had gotten out of control for some time. I found this site on the bellflower - Zombie Weed LOL - good name for it!

Thank you for ID'g the Japanese Anemone! This is planted in her front yard by her front porch - a much more attractive and contained garden area! I dug up a bit of it and will plant in my shade garden :)

The top ones look like they COULD be kochia, the flower panicles and the leaves look mostly right. The thing that gives me pause is the leaves look smooth (glabrous) in your picture and kochia has pubescent (fuzzy) leaves. Google that one to be sure, it's hard to tell. If it is, that's another one you'll want to rid yourself of. Its an annual tap rooted weed but an aggressive self seeder.

Number nine is hardy plumbago.

Thanks Zach! I don't remember if the leaves were fuzzy or not - didn't touch them. But I'll let her know that's what it might be, and leave it to her! Does look like it!

Just a heads up on the plumbago/Ceratostigma! It's another one that can--how to put it nicely?--get out of hand! When I was selling it it was one of the things where the rhizomes would be growing out of the holes in the bottom of the pots! That was enough to scare me away from ever getting one--even tho they do get pretty true-blue flowers, and the foliage turns red in fall. It can be very pretty when you have both the red leaves and blue flowers at the same time--but one needs to decide if it's worth it to be constantly fighting to "keep it where it belongs."

It sure looks to me like the previous owners of that house put in a lot of invasive to semi-invasive things! I'm sure they looked good for the first few years--and now someone else is going to have to deal with the Years Later Version of them! Show your neighbor some of the things at your house and suggest that she slowly get rid of all the invasive/aggressive stuff and start to replace it with some stuff that will behave itself and be less work in the long run. You can tell her about the swaps, or offer her small starts of some of your things! (No! I don't USUALLY give away other peoples' plants!) She'll thank you for it down the road!

The top one might also be a type of amaranth rather than kochia, but still another weed. In any case, it doesn't look like something anyone would purposely plant.

Kochia, amaranth, and the lamb's quarters from the other post probably came in via wind or already in the soil. They are all very common weeds. I get them all over the place and we spend a significant amount of effort trying to control kochia (and the Russian thistle that typically grows along with it) at work. Many birds seem to enjoy it though, I watched a flock of about 50 lark buntings hanging out in a patch of it for about a week straight l.

Yea, Skybird - I thought I'd pass along the link to RMG to her in case she'd like to lurk and/or post. I'm not sure how much she is into gardening (I know she said she wasn't much into growing vegetables), as I just met her the one time when I was looking for plants to go with my irises and posted on the NextDoor group. But I think she'll appreciate what info I can pass along to her from these ID's - especially about the things she might want to get rid of!

Wow! I have that purple bell flower and it showed up for the first time this year. My reaction was the same at that article, I didn't plant that but it is pretty I will leave it. It is going to be pulled out now. I don't need any more invasives.
