i am in adrian mi ... prime planting time in MI ... is ground thaw in late march ... minimum 6 to 8 weeks before leaf out ... OR!!!!! and late sept thru about now ... so this is your window of opportunity ... for next year ... gee tree farm is just north of jackson MI ... off I-94 ... with a 15 acre arboretum .. and hundreds of acres of trees... it would be a brilliant trip ... NOW ... call ahead... ask for cary ... and explain what you are looking for .. and ask if their field trees are still holding leaves.. and if you could mark some for next summer .. it might require a deposit ... and that is up to them ..... [i would have you mention my name.. but i dont know if it would be a positive.. lol ] .. make an appointment for someone with a golf cart to whisk you around the property .... you might be able to find some out your way also ... google tree farms grand rapids ... the larger the tree.. the more roots you cut off to transplant ... no tree will perform to expectations until it regrows its root mass .. so a larger tree.. will take years longer to recover ... smaller will get 'established' faster .. and can outgrow a larger specimen.. inside 5 years .. not to mention.. if you are doing this yourselves.. how to move.. transport ... carry.. and plant.. a humongous ball and burlap.. sans heavy machinery ... i have tried that.. nearly ended up needing surgery .. not cool ... my dichotomy.. is based on you doing it.. versus big checkbook professional installation ... its not that it cant be done... its what can be done in your budget .... i am impressed you are so far ahead of the curve... usually peeps want instant gratification.. rather than planning a year out ... should you be thinking of doing this yourself.. read.. digest. and commit to memory.. EVERYTHING at the link ... doing it the right way... really matters .... ken Here is a link that might be useful: link

Personally I have no issue with using "pine" as a general term for "conifer not otherwise specified" mainly because that seems to be how it was used historically. After all, a pinetum is a an arboretum full of conifers, and the umbrella pine, Huon pine, King Billy pine, and Norfolk pine are in the families Sciadopityaceae, Podocarpaceae, Cupressaceae, and Araucariaceae. Personally though, I think we should just start calling them all "Yule trees." It's neither taxonomically nor politically incorrect, and sounds almost as nice as "pine" when you substitute it. As for that particular tree, it's definitely in Cupressaceae, and probably a Cupressus sp. (Athrotaxis cupressoides is the only non-Cupressus species I know of that has a form and foliage like that, and it wouldn't be a garden plant in Maryland.) Beyond that, I don't know. Does Cupressus arizonica grow in MD? I agree that it looks like one, but I thought it was prone to root rot in humid climates.

I would say scots pine, pinus sylvestris, but I guess they could be some superficially similar american species of pine
