It looks like wild rosemary but is there such a plant? [8-13: Andrea says Andromeda polifolia or bog-rosemary so we're going with that for now.]

??? Shepherd's purse maybe?

??? (10/6: could this be nutsedge???)

12/26/09 update: Aporn says this is an obedient plant.

Physostegia virginiana.

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

???

???? Boneset maybe?

And this is ...?? (9/18: Possibly white wood aster.)

Eurybia divaricata.
This is what I'm calling it until someone corrects me.

Now that this weed has finally bloomed I should be able to identify it. (Clammy Ground Cherry, 9/23.)

Physalis heterophylla. (Yes, Michelle, it is a nightshade.)

What IS this stuff? St. John's Wort, I do believe.

Hypericum perforatum.
