I've recently started a garden and was thinking of incorporating native plants into using cuttings, or possibly transplants. I took a walk around the fields and woods near the house and took pictures of some of the plants I'd like. I noticed quite a few I didn't know the names of but was able to identify a few (like the tartarian honeysuckle that's in abundance around here - which is an invasive species I guess), but a few still allude me. I was wondering if anyone could help identify the following plants:

This was growing everywhere, it's a shrub, 3-5 feet high, no flowers, stiff, almost waxy leaves, and odd shaped berries that are still green.

And the berries (possibly buds?):

Then there was what appeared to be a shrub, but was actually several short plants in a cluster. I was thinking young beech trees, but was told beech trees don't get flowers, and this plant had flowers.

Lastly, there were a few of these flowers growing near some burdock, but I didn't think they were burdock flowers.

Any clues? Thanks!
