My daughter planted a horsechest nut seed 15 plus years ago. The tree is big and fine, but has never flowerd/bloomed. Any ideas on what it needs an how to push it?

While there is a chance you have a sterile tree, this would still not explain the lack of blooms. The amount of time you have had it tells me it has been flourishing. Normally, these trees will develop blooms within the first 4 years and begin setting seed within 8. Perhaps there is a problem with pollination or you could try add phosphorus to the soil, such as bone meal. I am sorry I cannot be of more help to you, as this has me baffled as well.
