Abstract
A new and distinct variety of ornamental pear tree named Valzam is provided. The new variety can be readily distinguished from the Cleveland Select variety of callery pear tree (nonpatented in the United States). For instance, the new variety is shorter in stature with a more compact branching structure having less scaffolding, generally forms lateral branches having a larger diameter, forms lateral branches leaving the tree at a lesser angle giving the tree a more pyramidal form, and forms larger and darker leaves which turn a brighter and more intense shade of red approximately two weeks earlier. The new variety is particularly well suited for growing as attractive ornamentation and/or for shade purposes in the landscape.
