There's no way I can name 15 species, but here's a start (yes, there are guesses in there!):
Name: Judy Mid Atlantic Coastal Plain USA (Zone 7b)
Ha Ha When the fox lived under my school bus there were a number of skulls left behind. Hope I'm correct on that one at least.
Muddy what do you think the three red fluffs are at the bottom? I thought V.'Cardinal Candy' or perhaps sedum (Autumn Joy). How about the orange berries on the top right side? American Bittersweet? Which did you think was Magnolia?
I agree on Winterberry, boxwood and American Holly. Think the candles (though white) are Bayberry? And, too bad rocks don't have species! Any idea on the brown leaves on the bottom left?
This is somewhat like trying to guess each piece of candy in a Russell Stover Assortment without the box top!
