I agree. Mine aren't quite as far along as yours but I'm a couple zones colder. It's commonly called wild ginger.

I don't know the scientific name, but it's what we used to call "Honeysuckle's" Wow, wish I had a load of them! They used to grow in the woods, and they smelled SO good~~~

Looks like Elaeagnus umbellata, a weed. Here is a link that might be useful: Elaeagnus umbellata

Also known by the street name of "wandering jew". Point of note: When I clicked through on the link and went to your Flickr gallery, I noticed an extremely toxic plant in the pictures immediately after these - and that's Oleander. Long, cats-eye shaped leaves with f-petal pink flowers (the flower color varies). Eating a single leaf can kill a human, so you can guess what it will do to a small animal.
