Help me identify

I have been wracking my brain in attempting to identifying these plants in my yard. Can you help me?

 

First is old seed capsules of Honesty (Lunaria annua).

 

Thank you! It's been driving me nuts for 10 years. They are growing wild in my back yard and are soo pretty in the winter when the leaves turn white.

 

Second one has the appearance of a Bidens to me.

 

#2 Looks like a perennial Marigold to me such as Tagetes lemmonii

A straight-on view of #3 would be helpful.

 

With something for scale, coin et cetera.

To estimate the size, imagine that the entire picture is about 1 sq foot in size. The leaves and small blooms seem delicate and fragile, but they are really hardy and seem to climb like a vine.
