Hi I am new and live in the Northeast. We have recently built a new home on a lot that has never been groomed ACK! Anyways I have lots and lots to do, but need help in identifying if some things I should leave alone or get rid of. Any help would be greatly appreciated. This is growing in a large shaded Pine grow along with lily of the valley and some lady slippers, any ideas what it is? So afraid because of the leaves in threes thing that it might not be such a good thing to have around. Seems to be spreading lightly along the center most portion of the shaded area. Thanks so much!
