Abstract
A new and distinct variety of Euonymus fortunei which is a branch mutation of the Emerald'N Gold variety (i.e., U.S. Plant Pat. No. 2,231) is provided. The new variety possesses smaller leaves than the parent variety which are slightly more elliptic in shape and attractively variegated in color. More specifically, the mature leaves are dark green and have light to medium yellow margins. The new variety is shorter and more spreading than the parent and can be characterized as having a distinctly dwarf growth habit which renders it highly suited for use as a semi-prostrate ground cover.
