Looking for native pine tree source
I would like to plant some native pines in my yard but cannot find a source for them locally. I am looking for trees of any size, but particularly larger sizes because I have a few seedlings I have grown myself. I'd prefer trees grown from a source as close to central PA as possible. My first choice is Pitch Pine (Pinus rigida). I'd like to try Shortleaf Pine (Pinus echinata). I am also interested in Virginia Pine (Pinus virginiana) and Table Mountain Pine (Pinus pungens). Has anyone seen these offered for sale or have any ideas where I might try to find them? Also, can anyone tell me where I can find Shortleaf Pine growing in the wild (a native stand)? This is the time of the year when Pitch Pine drops seeds, and if Shortleaf Pine does the same I might try to collect some seeds and start Shortleaf Pines myself.
