'Jersey Princess' American holly is one of the top five evergreen tree-sized hollies for the Ohio River valley region.

This fine tree (selected by Dr. Elwin Orton of the Rutgers holly breeding program) boasts lustrous clean dark green foliage, heavy annual crops of bright red fruit, and exceptional winter hardiness.

It is easy to propagate from winter cuttings with bottom heat. No American holly collection should be without this regal plant.
