Abstract: This species of Viburnum dentatum turns brilliant red in October and maintains its red color late into November in USDA hardiness zone 5. In early June, it produces dense, flat white clusters of flowers, which last for 3 weeks. The shrub is very cold hardy and can withstand temperatures of −20° F.(−28° C.) without damage.

Abstract: A new cultivar of Hamamelis virginiana characterized by its exceptionally large and abundant flowers borne on large, dense clusters closely spaced on slender twigs.

Abstract: There is disclosed a flowering Higan Cherry Tree of the variety Prunus subhirtella which produces abundant quantities of deep purplish red blooms of semi-double form and long lasting qualities, the buds being capable of resisting bitter cold as low as minus 17 degrees F. in the vicinity of Princeton, N.J. under cultivated conditions.

Abstract: There is disclosed a new variety of Malus hupehensis which produces abundance of flowers having strong purplish pink appearance on a tree in bloom, dark red young leaves, becoming dark green when mature, with high resistance to apple scab fungus and fire blight.

Abstract: A new cultivar of Hamamelis mollis plant is characterized by exceptionally large and abundant flowers with a rich fruity fragrance. It is also unique in that the leaves promptly drop in the fall, not persisting in an unsightly condition throughout the winter as in ordinary Hamamelis mollis seedlings.

Abstract: A Zelkova serrata variety of larger size than Zelkova serrata "Village Green", U.S. Plant Pat. No. 2,337, having vase-shaped configuration, larger leaves of paler green, turning more orange than rusty red of "Village Green", in the fall, cold hardiness at temperatures to -16 degrees F., good foliar resistance to air borne pollutants and good drought resistance in heavy clay soil.

Abstract: A Sophora japonica tree discovered in a block of standard Sophora japonica seedlings, specifically in the block of Sophora japonica seedlings known as Regent, an unpatented variety, and which my instant variety is distinguished by much more narrow and upright head of branches having a narrow rectilinear crown in outline, more free of cold weather twig die-back than normal seedling grown Sophora trees, resistant to stem cankers, and sparse flowering and fruiting which makes the new variety valuable for street trees grown in paved areas.

Abstract: A flowering cherry tree selected as a seedling in a block of open pollinated variety Prunus yedoensis "Akebono", (unpatented) distinguished from "Akebono" by the strong pink color of its abundant flowers when fully open, "Akebono" flowers being pale pink by comparison, the variety hereof being vigorous with spreading growth broader than tall, the flower buds being resistant to freezing, blooming abundantly when regular "Akebono" trees lost as much as ninety percent of buds due to freezing, and the bark showing no injury to minus 19 degrees F.

Abstract: A flowering Crab Apple Tree denominated "Bridal Bouquet" selected from a block of seedlings of Malus "Katherine," an unpatented variety, which seedling was noted as having abundant, large size, pure white-colored double flowers and in continued growth the leaves have been unaffected by Apple Scab disease or Fire Blight disease, even in wet summers, and thus die-back is not caused such as is experienced by standard Japanese Crab and Tea varieties.

Abstract: A Norway Maple, Acer platanoides, denominated "Princeton Gold", which displays a bright yellow foliage as the outstanding feature of appearance, as compared with the leaves of other seedlings which are of a normal green color, the bright yellow persisting throughout the summer months and resistant to sun scorching or burning, asexual reproduction establishing the characteristics as continuing from generation to generation.

Abstract: An Amelanchier canadensis tree grown in a cultivated area of a nursery near Princeton, N.J., which tree is distinctly columnar in overall appearance in contrast to other Amelanchier canadensis trees which are much more spreading, the instant variety being resistant to leaf spot fungi which causes defoliation of the usual Amelanchier trees in warm, humid weather, and the very abundant blooms of the tree which substantially hide the branches, the fall colors of its leaves providing a mixture of reds and purples.

Abstract: A Malus hupehensis tree providing abundant red flowers and small, very glossy red fruits, having resistance to defoliation in hot humid summers and to leaf injury from apple scab fungus or mildew which severely affects other similar trees in an adjacent area, the tree growing rapidly and displaying a wide spreading crown.

Abstract: An Amelanchier laevis tree having exceptionally vigorous growth, reaching twice the height of prior known Amelanchier laevis trees during the same growth period, the growth being tall and narrow, blooms exhibiting long, drooping racemes with many white flowers, new foliage of dark, reddish orange color becoming thick and dark green, as they mature, with resistance to hot, humid weather.

Abstract: A seedling of the variety Acer palmatum "Bloodgood" (an unpatented variety) noticeable for its vigorous growth, deeper red color in the summer, greater height of growth as compared with other "Bloodgood" seedlings of the same age, cold hardiness and non-susceptibility to tip die-back of the summer growth, from cold winters.

Abstract: A seedling discovered growing in a cultivated area in a row of seedlings resulting from a cross between Robinia hispida, and Robinia pseudoacacia, and noticed because of its more vigorous, narrow upright crown of branches, and particularly at the time of blooming for its abundant purple pea-shaped flowers.

Abstract: A Quercus palustris newly found seedling which has developed into an unusual, very upright, narrow, fastigiate tree, not heretofore noted in the pin oak family, with very dense branches having glossy dark green leaves.

Abstract: A new and distinct Clethra variety characterized by its hardiness and its ability to bloom late in the year coming into fill bloom in September, and having flowers with white petals from pale green buds.

Abstract: A new and distinct variety of Maackia amurensis tree, characterized particularly as to novelty by its straight trunk with attractive peeling coppery bark, exceptionally vigorous grwoth and its very large showy and abundant white panicles of flowers, born upright in closely clustered panicles at the ends of thick twigs.

Abstract: A new and distinct Prunus plant characterized by having a very vigorous growth, being one third larger than sibling seedlings in the same row, and for its very abundant, large white flowers, unusual in the species which normally bears pink flowers. The autumn foliage turns a brilliant red color in late October. It is the most cold hardy of the white Japanese cherry trees.

Abstract: A new and distinct Forsythia variety characterized by the very large size of the flowers which have a rich golden color and with much broader petals than any other Forysthia variety known to me. The flowers are very dense on the twigs so that the shrub is a solid mass of gold when in bloom. It forms a dense, rounded shrub, broader than tall. The flower buds survive cold winter in USDA hardiness zone 5-A when the flower buds of Forsythia intermedia varieties have been killed.
