Abstract
A new and distinct Buxus cultivar of unknown parentage is provided that is believed to be an interspecific cross. The attractive medium-sized evergreen shrub exhibits a dense upright mounded and compact growth habit. No pruning is required to maintain the compact and mounded growth habit. The glossy foliage is deep olive green throughout the year and exhibits no substantial change in coloration during the winter. The winter hardiness also is exceptionally good. The new cultivar accordingly is capable of providing attractive ornamentation in the landscape even during the coldest winter months. No fragrance is emitted by the foliage. An unusually rapid growth cycle is possible following propagation which renders the new plant well suited for commercial production in containers.
