Three Shrubs to ID

A few more mystery plants to ID...

The first shrub has leaves that smell like a cross between mint and sage (at least that is how it smells to me).

This second one looked like a weed, and then it flowered and now I don't know.

The last one is a small shrub that seems like it might be a volunteer, though it looks like it has been there for awhile.


Thanks for any help you can offer.

 

2. Looks like Lunaria annua. Common name Annual Honesty.

3. Looks like an Astilbe.

First is Salvia officinalis. It is the only one of these that could be called a shrub, the other two not being woody plants.
