Abstract: An advanced generation interspecific hybrid of Cornus kousa and C. florida that is distinguished by its exceptionally high vigor, attractive foliage, very floriferous display of white floral bracts, high level of winter hardiness, tolerance of drought and shade, and high resistance to the incitants of Powdery Mildew and Dogwood Anthracnose.

Abstract: A cultivar of dogwood tree is characterized by a unique combination of red floral bracts and a dwarf rounded shape.

Abstract: Rutzan is a new and distinct variety of evergreen holly distinguished in that it combines from three species (Ilex aquifolium, Ilex rugosa, and Ilex pernyi), desirable landscape and production traits which distinguish it from all other forms of Ilex. 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.

Abstract: An interspecific hybrid of Cornus kousa×C. nuttallii exhibits the vigorous nature and the floral display of large, white bracts of plants of C. nuttallii and the dark, glossy green foliage and disease and insect resistance of plants of C. kousa. The hybrid thus provides a new, unique, and superior large-bracted dogwood for landscaping purposes. Plants of C. nuttallii become very large in nature in areas where they are indigenous but seldom thrive in other areas. Plants of this novel hybrid are expected to thrive in many regions of the world where plants of C. kousa perform well.

Abstract: An advanced generation interspecific hybrid of (Cornus kousa×C. nuttallii) that is distinguished by its exceptionally high vigor, superior foliage, floriferous display of very attractive and exceptionaly large white floral bracts, high level of winter hardiness, good drought tolerance and high resistance to the incitants of powdery mildew and dogwood anthracnose.

Abstract: An F1 interspecific hybrid of Cornus kousa×C. florida that is distinguished by its large bracts, a compact and dense attitude, wider than tall, and a flowering habit in the middle of the blooming season for the commercially available cultivars of Cornus kousa×C. florida. The cultivar has a high level of winter hardiness, and is highly resistant to dogwood anthracnose and the common dogwood borer.

Abstract: A new and distinct variety of evergreen shrub holly distinguished in that it combines from three species (Ilex rugosa, I. integra, and I. pernyi), as well as exhibiting desirable landscape and production traits which distinguish it from other forms of Ilex. Plants of the new variety exhibit a moderately vigorous rate of growth, develop a dense, self-compacting, moderately broad conical form of moderate size, possess small, shiny, dark green leaves with a beautiful finely rugose surface and non-spiny margins (consumer friendly) with bright red fruit displayed on wood of the previous season's growth, and are outstanding for their high level of winter hardiness.

Abstract: The outstanding characteristics of the cultivar hereof comprise the white bracted display over a period of time typical of most plants of C. florida, an important distinguishing element of this new hybrid comprising the fruit which are bright red and much larger than the fruit typical for C. florida being nearly tubular or almost uniformly cylindrical in shape, the volume of the fruit being substantially greater than the volume of fruit of other cultivars, the vegetative and floral parts being winter-hardy in the region of New Brunswick, N.J.

Abstract: The plant hereof is notable for its dark red floral bracts and rather small compact form of tree characterized by branching of a densely profuse form being more dense than other clones of C. florida.
