Abstract

Plants of the new variety exhibit a moderate rate of growth, develop a densely branched narrow to moderately broad conical form of compact size, possess small to medium sized dark green spiny leaves, produce an abundance of bright red fruit well displayed on wood of the previous season's growth, and are outstanding for their exceptionally high level of winter hardiness.
