Abstract
A new and distinct Boxwood plant is provided which originated as a limb mutation of the ‘Green Velvet’ cultivar (non-patented in the United States). The new cultivar readily can be distinguished from the ‘Green Velvet’ cultivar in view of its significantly larger leaf size. The growth habit is dense, mounded and compact. Attractive deep olive green foliage is formed which well retains its coloration throughout the year in the absence of any substantial color change during the winter. Excellent winter hardiness to at least U.S.D.A. Hardiness Zone No. 5 is displayed. The plant is well suited for consistently providing attractive ornamentation in the landscape.
