2 and 3 look like Barbarea vulgaris
6 is Japanese knotweed
7 is Pachysandra procumbens, Allegheny spurge.
8 is Oenothera biennis, evening primrose
9 is Rudbeckia laciniata
10 is Hydrangea paniculata

Hope that helps.

9. Looks like a Viburnum rather than Hydrangea paniculata. I don't know the species you'd find in your area but V plicatum is similar.

1. Looks like a Rubus, raspberry
4. Looks like a Veratrum, false helleborine, but again I am not familiar with species you might have in your area

#7. Looks more like Pachysandra terminalis, Japanese pachysandra.

To go along with what flora_uk suggested, #4 is likely Veratrum viride. Also agree with Japanese pachysandra since the leaves are smooth and somewhat shiny.

I am wondering if these images are being changed around a bit, as currently #9 looks like virginia waterleaf!

The Viburnum (which is #10 now?) looks like hobblebush, or Viburnum alnifolium. Those aren't male and female flowers, rather they are perfect flowers in the middle and sterile ones around the edge.

The pictures look the same as yesterday, I just didn't do a very good job of identifying them. Sorry.

1 Rubus. Some kind of Blackberry/Rasberry/Dewberry
2 and 3 Something in the Mustard family - the common one this time of year is Barbarea vulgaris, Wintercress. Could easily be that.
4 Veratrum viride, False Hellebore
5 Another mustard. Could be the same as the others. Need more details to ID them.
6 Japanese Knotweed. Run!
7 Pachysandra. A commonly planted groundcover.
8 Evening Primrose, probably a weed. Oenothera sp
9 Not sure of that one. Some kind of Buttercup, maybe. Ranunculus sp.
10 A Viburnum. Linden Viburnum, maybe? Or Doublefile? Not that many have the big and little flowers together.

Jeanne, we don't always name them all right. Can just get confusing sometimes with so many pictures.

thanks guys. super helpful! As far as number 1, wouldn't a berry plant -- raspberry, blackberry, dewberry have three leaves instead of five?

They can have five.
