I really need your help. Please tell me what the name of this plant is. I received it from a new home-owner who dug it out of his backyard because he isn’t a plant-lover. No one can figure out what it is & I NEED to confirm it isn’t poisonous before I decide where to plant it. I have a new puppy that likes to bite my plants in the backyard so I definitely wouldn’t want to put her health in jeopardy.

 

Please help me ID this plant or let me know who can. I need to get it back in the ground SOON.
