Found in the woods around our new house (and some from the flower beds). Thank you in advance!

#1 The long-leaved plants:



#2 Not the tulips:



#3 Cranesbill, wild geranium, anemone?



#4 Violet?



#5 The wood lily type plants:



#6 Another type of wild geranium?



#7 Not sure:




#8



#9 from the flower bed



#10
Looks so familiar but I just can't place it. Hydrangea? Lilac?



#11
Anemone?



#12
Wicked big thorns



#13
Same as #11?


#14
The fern in the center


#15
Fern



#16 Columbine?

#2 Lilium?
#3 Delphinium?
#6 Creeping Buttercup?
#9 Berberis?

Sorry, all guesses but without close up shots and flowers it's difficult to say more. Try getting more shots when they flower, it would be best to put each plant in a thread of it's own with as many photos of stems, leaves and flowers as possible.

#2 Lilium
#3 Delphinium or Aconitum
#4 Pyrola sp.
#9 Berberis
#16 not columbine

16 is the yellow blooming Chelidonium majus ???

#5 is Canada Lily (Lilium canadense).
#15 is Sensitive Fern (Onoclea sensibilis)

Here are some closer pictures of the possible canada lily? I will get better ones later today. You can click on any of the pictures to get the large version.

At least some, if not all the leaves of Lilium canadense are arranged in whorls or partial whorls. #5's leaves are uniformly scattered. I don't think #5 is even a monocot. It's not Lilium canadense.

The white flowered ground cover type plant in the upper right of pic #5 might be Maianthemum canadense.

By the way kuklachica, you have a nice crop of poison ivy, too. Do be careful! Sorry I didn't notice it on the first pic.

Is this the poison ivy you see? I have been walking in it all weekend. I grew up in Maine, ALWAYS in the woods and have never had poison ivy, even when all my childhood friends did all summer. My dad can pick it with his hands and doesn't react to it. Hopefully I am that lucky!

No. There is no poison ivy in that pic.

Look at this:
Black arrows (above) not poison ivy
Red arrows (below) poison ivy


Maybe you have something there that I don't have here.
Follow the leaf stems down to where it connects with something. Poison ivy has a woody stem. Farther south they get tall and even vine into trees. But in the north they stay very short, but you should still be able to detect a woody stem. Some people are not allergic (me too!).

Any idea what this is? Growing in shade under a pine tree only in one place, ground cover.

Trout Lily (Erythronium).

Hard to say which species without knowing what part of the world it was growing in and/or a picture of the flowers.
