Weeds weeds everywhere

Already this year a lot of time is being taken up weeding. But, as you can see, there is a lot of square footage in this garden.

There are many different types of weeds encountered here. I am not good at identifying them but I would love to know if anyone else can. I have noticed from year to year that the types of weeds change. Once I eradicate a certain type, another type becomes more prolific. This year, we have the following:

This grass. I wish it would grow in the actual yard. When i yank it up, i throw it over into the yard, hoping it will take root there. All i really have in the "yard" is crabgrass, patches of dirt, and weeds. But unfortunately not this particular one. Which i don't want in the garden.

There's this one, which looks like an herb, doesn't it? I wonder if this is a remnant of something the gardener before me planted, before I came onto the scene. The garden layed fallow and became a jungle for a couple of years in between the last gardener and me. But there is something fragrant and tasty-smelling when I weed, and I have always suspected this is it.

It grows up to look like this:

I mean, it sort of looks like something you would munch on, doesn't it? (I know the bunny thinks so.) It is hard to pull up, has a deep root system with thick, ropy roots along with thready shoots, that, if you don't pull up when it's young, turn into woody substances.

Then there's this one:

It looks like lily pads, sort of, and is an invasive vine. It's very easy to pull up. It has little purple flowers but the root system is not deep and it's thready.

This one is easy to pull up but pops up all over the place. Before I was familiar with it, I thought it was one of the plants I had planted, like a pea or something (last year.) Now I'm wise to it. Not sure what it actually is, though.

Then there is this:

This is a seed pod dropped all over the garden (ALL OVER IT) by some tree in the vicinity. It looks sort of like a feather, doesn't it. A beautiful piece of nature's handiwork. On the left hand side you have a lighter than air, papery substance made for the express purpose of taking flight. On the right hand side you have a seed encased in a pod. It lands in my garden, plants itself, aaaaand:

The pod begins to disintegrate. The seed germinates. And a little tree begins to grow.

And then I yank that sucker out.

But there is no way I can ever pick up all the pods laying all over the garden. Lordy.

Anyway, if you know what any of these weeds are, lemme know!
