tall slender oak trees
In our Green Hills Mall here in Nashville they have planted in the center island a row of oak trees that within 2 years are very tall and more importantly very slender the branches are not wide spread but short and cylinder in shape Do you know what variety of oak this might be I would like to plant some Thanks
Maybe pin oak Quercus palustris , they often have a slender form when they are young. They will fill out and spread more as they mature. See Google images for that species.
I don't know the area or your local tree species. I tried to see the trees you asked about from a Google maps street view, but couldn't find them.
It's best if you ask the facilities/grounds manager at the mall, a local arborist/tree service, or best may be a local nursery that would have an interest in selling you the trees.
