1. I'm not sure but I think it could be a Scabiosa.
2. Chelidonium majus 'Flore Pleno'
3. I'm not sure?

Thanks Sharon! So would you say that chelidonium is a weed or a flower? It looks kinda messy but I don't mind it where it is.

You could be right about scabiosa, I did wintersow some of that... which would make me very happy because I always wanted some but couldn't get it to grow at my old house. It looks pretty enthusiastic here.

The third one is about 2.5 feet tall and has large leaves. I'm really stumped too. It's growing in a messy area of Hemerocallis fulva that the dogs run through and mangle.

Double Greater Celadine is beautiful in my eyes, if it seeds all over and takes over the other plants then I would consider it a weed. Apparently this plant is an annual in our zone. It will reseed, therefore please try to collect me some seed this fall ;)
I tried wintersowing this a few years back but it didn't germinate, I'm suspecting the seed was old.

The third photo is stumping me, can you take good close up photos of different angles today?

Here is a link that might be useful: Double Greater Celadine

For sure I will save you some seeds Sharon! I'll be on the lookout for carrion vine seeds this summer too, I saw some in the mayor's yard last year and snuck in at night to steal them but they were gone by the time I got there, LOL. The things I do for you.

Here is the third whatsit again... the leaves are bigger than my hand and another branch of it looks like it might be forming a flower bud. I guess that will narrow it down if it blooms.

The third photo is driving me nuts, I'm baffled, I've seen it too but can't recall a name!
Maybe post over at the name this plant forum, or let it flower which will greatly help to recognize ;)

Oh I'm sorry is it bugging you just a little bit Sharon? Mwahaha! Ok I have posted it on the ID forum, I'm sure someone there will know. Although it is fun to torture you.

LOL it's Giant Ragweed. Isn't that pleasant!

Oh geez, here I was going to ask you for seed of that one too. LOL

I knew I seen it before!
