Abstract

A Pittosporum plant possessing a dwarf habit of growth, and medium green elongated leaves with irregular variegated margins separating creamy white tips.

Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.

We claim: 1. A distinct, new and improved variety of Pittosporum tobira named Shimamoto Pittosporum, substantially as herein shown and described and which is principally distinguishable by: (a) its ability to asexually reproduce and maintain its unique characteristics through succeeding propagations; (b) a dwarf size which makes it appropriate for use as a border plant, a small hedge, in planter boxes and as a pot plant; (c) a slow rate of growth resulting in minimal maintenance by eliminating frequent pruning and longer retention of an aesthetically pleasing shape; (d) a shrub possessing several colors due to its variegated nature of elongated evergreen leaves; (e) leaves consisting of a medium green color with irregular variegated margins separating its creamy white tips; and (f) leaves that grow in a whorl on the branches due to an alternate pattern of growth.
