I bought this from a local Pacific NW Christmas tree farm (now out of business) as a seedling. I am not real familiar with pines, and have been trying to identify which type of pine this is. Any help?

Hmm.
Very hard from a pic.

Suggest you try this key...search 2 needle pines.

Thanks Silver. I always like using botanic keys but often have a hard time finding ones that are not too technical for me. I'll stomp out in the field and see if I can work my way through this one. Our native pines on the west side of Washington are lodgepole and western white, but that doesn't mean a tree farm might have planted something else.

Agree with the two-needle pine prognosis; if this was in the eastern US, you would have more-or-less Pinus nigra and Pinus sylvestris to choose between. And that would be easy, because Scots Pine has quite short needles compared to Austrian Pine's quite long needles.

In the PNW, you can probably grow a lot more species less often seen out here in the Ohio River valley region.

You could provide more images of the WHOLE plant, as well as some images of any stray cones around, the bark on new branches, older branches, and the trunk. Those can provide some positive ID qualities, too.

Additional 2-needle pines that are planted as ornamentals:

Pinus densiflora Japanese Red Pine
Pinus mugo Mugo Pine
Pinus resinosa Red Pine, Norway Pine
Pinus thunbergii Japanese Black Pine
Pinus virginiana Virginia Pine, Poverty Pine
Pinus pungens Table Mountain Pine
Pinus banksiana Jack Pine
