Sophora japonica Princeton Upright

Abstract

A Sophora japonica tree discovered in a block of standard Sophora japonica seedlings, specifically in the block of Sophora japonica seedlings known as Regent, an unpatented variety, and which my instant variety is distinguished by much more narrow and upright head of branches having a narrow rectilinear crown in outline, more free of cold weather twig die-back than normal seedling grown Sophora trees, resistant to stem cankers, and sparse flowering and fruiting which makes the new variety valuable for street trees grown in paved areas.

I claim: 
     
       1. A new and distinct variety of Sophora japonica tree, as herein shown and described, characterized particularly as to novelty by the unique combination of more narrow, upright head of branches having a generally rectilinear crown in outline, resistance to cold winter twig die-back, freedom from stem cankers caused by a fungus of the genus Fusarium though lightly to heavily injured, and sparse flowering and fruiting as compared with standard Sophora japonica trees.
