Not sure what a tung oil tree looks like. Can you email pic? We are located near St. Thomas We have Araucaria seeds that I brought from Brazil. We grew 3 of these in pots for last 3 years but unfortunately when we were away this winter they dried out & died. Check them out. If you want these seeds I can send you some. Regards rwthomas@sympatico.ca

It's rubra. I have that leaf etched in my mind. Agree with Embothrium.... last years acorn caps on the ground or full acorns in combination with leaf is key to identification for most folks. The most serious of folks and experts know the buds, too. Dax

out of focus really doesnt help ... but it doesnt look like pine to me ... im thinking abies ... fir ... but im cant even feel secure on that with the blur ... where are they ... z5 is half the US ... as trees.. no conifer stops growing at some magical height ... its all about annual growth rate .. and how fast the get to height and go right past it.. most size estimates in conifers is at 10 years .. double the size at 20 .... are there power lines?? why 25'? and how long is the installation ... or are you talking one plant???? one thing for sure.. plant a diversity of plants ... if more than one ... ken

Looks like the bark appearance changes as the tree ages. Mine is 17 years old max. Lots of variation given for height but this is another case of someone planting a tall tree too close to the house. Guess Im lucky the driveway hasnt lifted yet. Ugh!!
