Pinus strobus, Pinus nigra, or???








It appears to me that its needles are in groups of two, which makes me think it's Pinus nigra. What do you think?

As I often say...show us the whole plant! And - are there any cones present (on tree or on the ground)?

Groups of two eliminates Eastern White Pine (Pinus strobus) because its needles are in bundles of five, but it could also include Red Pine (Pinus resinosa) and Scots Pine (Pinus sylvestris). Scots Pine has much shorter needles than Red Pine or Austrian Pine.

Most likely your suspicion of Austrian Pine (Pinus nigra) is correct, as that is one of the most common landscape pines for that part of the country.

Thanks, John.

I don't have a picture of the entire plant in hand; it's deer-damaged and rather misshapen. I can, however, get one tomorrow if necessary.

It came from the Arbor Day Foundation, so I'm sifting through their offerings to narrow things down a bit.

It's 14 degrees here, and feels like 6 with the breeze...brrr!

Here's some frozen-fresh pictures...

I'd be confident in saying that is Austrian Pine (Pinus nigra) - definitely two-needled bundles, and much longer needles than Scots Pine. The "tightness" which the needles are held along the branches is typical for Austrian Pine, versus a "looser" way that Red Pine tends to look.

If you dare brave the frozen tundra again...put something in the closeups for scale - a quarter, a finger, a lens cap...

Ah! I knew I was forgetting something - scale!

Thanks for the help ...and the reminder.

At your service...

Red Pine has nice, soft needles that are slender and bright green. The Austrian Black Pine has dark green, stout needles that are very prickly and hurt when touched.
