Help with plant identification

I'm having a hard time identifying the following plants. I've consulted a number of plant encyclopedias but have been unable to come up with either a common or scientific name for them.

Any help here would be greatly appreciated!

 

#1 one of Galium species may be?
#2 Potentilla sp.

 

Thanks for the quick reply.

I've confirmed that #2 is Potentilla, still researching #1 (Galium?) and looking for ideas on #3.

 

The first is certainly a Galium, the third is likely a Cornus.

 

Cornus stolonifera 'Kelseyi'.

 

Bingo!

Thank you all for your help :-)
