The tulip tree photos

I bought my tulip tree from hollandale nursery. They were $180 and they were big ones. There was a Huge birch that costed $800. It was 20 feet tall. The roots were pruned but they were big. Hollandale is very expensive. They only had three tulip trees there. I got alot of birch tree seeds from female catkins that were old and very dry. I want to plant them in a pot. So heres the photos.
