A collection of Baltic wildflowers - Directly above left, a Polish weed of some sort. The upper right collection is from Lithuania. The blue Chickory appears to be a noxious weed the entire world over. Above that is what looks like what we call Klamath weed, but looking more closely at the petals, I'm not so sure anymore. The one on the left, I'm not sure, but then I'm not big into the composites, and there's a Silene of some sort on the upper right.

Below right are two from the Tiergarten in Berlin, a bright yellow primrose and a mystery flower (also seen in Lithuania), and on the far left is a rose from Helsinki.
