I'd say Knautia arvensis, Succisa pratensis or Centaurea sp.

I think this is garlic Allium sativium or onion Allium cepa.

Look at the leaves by the ground, ant A. ptarmica doesn't hae that many flowers in one bundle. :)

Pelargonium. :-)

This is a Salix sp. and I don't think it's possible to determine the tree at the species level.

I think it is Taraxacum as earlier mentioned, and it from the section Ruderalis. :-)

My guess is Asplenium scolopendrium, but this is from a "Norwegian view", so it can be something completly diffrent. I recomend good local litterature. But I'm pretty sure it's a type of fern. :-)

Yes, Caltha palustris is right. :)

Nice picture!

I guess this is Prunus sp. (or maybe Amelanchier sp. or Cotoneaster sp).
