I'm trying to learn about this tree. I wonder why it isn't planted more since it's an East coast native, and whether it isn't advertised as a hybrid with the more popular conifers. US forestry and wickipedia say it prefers zone 3-4 and high elevations, but among its great qualities: likes gravelly soil, shade tolerant, not as susceptible to pests as Balsam fir. I think I saw a stand of them in Central Massachusetts recently. They weren't pinus strobus, they weren't hemlocks... They can grow tall.

Seems to do alright, but it is not as tolerant of the heat of central NJ as Balsam Fir appears to be. Nice form when young... not sure how it'll look as an adult.

This tree likes well drained soil and it forms a narrow sillhouette.

Cones are small, 1 1/4' to 1 3/16" and fall from the tree soon after they mature.

Needles are 1/4" to 1/2" long and are usually curved upward.
