I do believe that is it ! I have some squirrel friends who love to, well, squirrel away, the raw peanuts we put out for them over the winter. thank you !

TJ, You may already be completely aware of this, but just in case you're not, invasiveness doesn't necessarily correspond to what you can see in your own yard. In other words, a plant could be extremely invasive (environmentally damaging by displacing native flora and fauna) and still not express serious aggressive tendencies in your yard. Seedlings could be eating your neighbors woods up without appearing in your own yard. Aggressive plants are not necessarily invasive (even if exotic), and invasive plant don't always appear (at least in the immediate vicinity of the plant) aggressive. The only reason I mention this is because you said that's what you had been "seeing". I'm not saying I think you have anything to worry about in the case of this species.

I'd be surprised if they get over 20-25m tall in the east; Pacific coastal Pseudotsuga menziesii subsp. menziesii is the really big one, but can't cope with eastern continental climates, while interior Pseudotsuga menziesii subsp. glauca is much smaller, and is also disease-prone in the east's high summer humidity. Yours is likely the latter. The pine seedling could well be Loblolly, though they're not easily identifiable at that age. Resin

Hello terriberry in Ohio, Plant number 1 is probably some type of rue (Ruta species). Crush the leaves and see if they have a very strong, distinctive odor. If they do, then the plant is almost certainly a species of rue. Plant number 2 (the tough-leaved plant with small purple flowers) is very likely a comfrey of some sort (Symphytum species). Without flowers, it is very hard to say what plant number 3 is although my best guess is that it is something in the daisy family. However, flowers are needed to confirm its identity. Kind regards, Rufino
