Good list....
I was going to suggest that you look around and see if you didn't already have Canada wild ginger there already....
Please don't plant invasives.
While the people meant well by suggesting them.... Planting vinca is a lot easier than trying to eradicate that thug after it destroys the existing forest environment.
A lot of people believe that they need to plant stuff in their wooded areas, and it would well behoove you to take your time, and spend time looking at what is there now.
Many of our desirable natives have periods of dormancy, and are not seen immediately....
How long have you actually lived on this property?
Edit:
Just read your last post....
Hedera helix is a nasty invasive.... Please don't spread that menace!
Japanese spurge sounds positively evil.
Your lake property should be covered in spring ephemerals.... Please don't kill the wildflowers by planting invasives!
