First one is Henbit or Deadnettle -- I can never tell which (they look very similar)
2nd one, if you are referring to the one with spikey seed pods that later on will dry and start shooting seeds all over (my kids LOVE them
) I believe is either called Bitter Cress or Upland Cress.
Towards the front in the same picture are clover and the creeping small mouse eared ones are Chickweed.
They are all within the lexicon of edible weeds, BTW.
I don't like Henbit/Deadnettle because they're too furry but they do have a sort of mushroomy flavor that adds a twist in a mushroomless salad, and the cress is better when younger and just barely flowering, chickweed stems are tough but those little leaves taste great in salad. I put clover flowers in a salad, but I think there's something you can do with the leaves? (... Hm can't remember. maybe tea?).
I don't always eat them, but then when I do, I remember all the ones I chucked in the compost pile or left to be mulch and wonder if I did the right thing.
The cress you do not want to leave lying around after the seed podss have developed to a certain point because they will use their last ounces of energy to complete their "pea shooters" and fling seeds all over the place even after they have been... Well not decapitated but made rootless.
