I really, really want to stop buying books, but how can I resist this?

Found all throughout my vegetable garden. What is it? It's not dandelion. (9/23: Dock for sure.)

Pokeweed! It might be the most common weed in my yard. Mostly in my flower beds.

Tickseed or coreopsis.

Money tree or money plant (Lunaria annua). They get nice translucent silver discs in the fall).

Also called honesty plant. I saw these purple wildflowers on the side of a road in April, not on someone's property but on city property. They looked like some kind of tall roadside weed, so I didn't think it was so wrong to pick just two flowers. I stuck them in dirt and they are now quite happy. Ugly but happy. I'll plant them in my wildflower garden, near the back. I read that they are one of those dreaded and dreadful biennials. Bloom twice and then die. I've come to dislike the whole idea of biennials. Seems unnatural. Plants should bloom always or once. Not some wishy washy middle ground. The top photo is from www.zum.de/stueber/lindman/212.jpg.

I've got 18 books on weeds and wildflowers and vines and grasses. And yet there are still some weeds that I can't find.

Books for my weed-identification project.

Johnson grass?

Plantain.

Plantago major.

Sowthistle (Sonchus arvensis). [5/24/10 update]

Wood sorrel (Oxalis stricta)

There seem to be three kinds of clover in my yard: Dutch White, which I'm planting from seeds b/c it stays short, this larger clover with yellow flowers, and an even taller clover with big purple flowers.

Garlic Mustard (Alliaria petiolata)

See related post on garlic mustard here.

Veronica spicata (spiked speedwell).

I'm calling this a weed because it spreads like wildfire. I think I bought a couple of plants 4 or 5 years ago and now it pops up everywhere. Has nice purple flowers so I'll let it spread around...up to a point.

Creeping charlie, gill-over-the-ground, ground ivy (Glechoma hederacea).

Mock (False) Strawberry (Duchesnea indica)

Violets. They get to stay.

Common fleabane.

Erigeron philadelphicus.

White flowers are what? They are peeking out of some violets and wild strawberry.

What's this?

What's this?

Another mystery weed.

Creeping jenny.

Yeah, yeah, yeah. I know it's invasive and non-native but I love it.
Lysimachia nummularia

Is this just plain grass?

Pulled from my back yard, which is no longer being mowed. Is this what happens to grass when you let it go to seed? So ugly.

Lemon balm. If I let it, it will take over the front flower bed. Very aggressive.

Not an evergreen plant so one strike against it. And it grows very tall if not trimmed. Strike two. But it's hardy and needs little water. Melissa officinalis.

Chickweed in bloom.

I tried to love this weed. I failed. Cerastium vulgatum.

Dutch white clover. Grown from seeds.
