Abstract: A new and distinct cultivar of Forsythia plant is provided that is an induced mutation of the ‘Lynwood’ cultivar (non-patented in the United States). The gamma radiation of buds was utilized to create the mutation. The new cultivar can be readily distinguished from the parent cultivar by the presence of a more uniform and compact upright growth habit which yields a plant approximately two-thirds the height of the parent cultivar. Showy golden yellow blossoms are presented over the entire plant in the springtime prior to the appearance of the leaves. The winter hardiness is good. The new cultivar is particularly well suited for growing as attractive ornamentation in the landscape.

Abstract: A new and distinct cultivar of Forsythia plant is provided that is a seedling formed following the induced mutation of the ‘Spring Glory’ cultivar (non-patented in the United States). Gamma radiation was utilized to create the mutation. The new cultivar can be readily distinguished from the parent cultivar by the presence of a very compact dwarf growth habit with exceptionally short internodes. Attractive bright yellow flowers are formed on an abundant basis. In view of the short internodes the blossoms well cover the relatively thick branches. Dark green foliage begins to appear during flowering. The winter hardiness is good. The plant is particularly well suited for growing in containers. The new cultivar also is well suited for growing as attractive ornamentation in the landscape.

Abstract: A new and distinct cultivar of Caryopteris×clandonensis plant is provided that is a seedling formed following the induced mutation of the ‘Heavenly Blue’ cultivar (U.S. Plant Pat. No. 1,091). Gamma radiation was utilized to create the mutation. The new cultivar can be readily distinguished from its parent by a more upright and more uniform growth habit, darker green foliage, more intense violet-blue flowers, and shorter internodes.

Abstract: A new and distinct red-flowered Lavatera plant is provided that is a somaclonal mutation of the ‘Breedon's Spring’ cultivar (non-patented in the United States). Callus culture and regeneration were carried out and the new variety was selected from the resulting plants. The new cultivar can be readily distinguished from the parent cultivar by the presence of larger and deeper pink flowers, a compact well-branched growth habit, and the presence of attractive relatively thick tomentose leaves. The new cultivar also is a tetraploid unlike the parent cultivar.

Abstract: A new and distinct white-flowered Pyracantha plant is provided that is a spontaneous whole plant mutation of the ‘Cadrou’ cultivar (non-patented in the United States). The new cultivar readily forms white flowers and red berries and can be readily distinguished from the ‘Cadrou’ cultivar by presence of attractive variegated leaves. A broad-bushy to flat-bushy growth habit with robustness and abundant branching commonly is displayed. Good resistance to scab and fire blight is provided to the grower. During observations to date less fructification than the ‘Cadrou’ cultivar has been noted.

Abstract: A new and distinct Cotoneaster dammeri cultivar is provided which unlike previously known cultivars displays very good tolerance to fire blight (Erwinia amylovora). The foliage is attractive dense medium green and is semi-glossy on the upper surface and dull and pubescent on the under surface. A creeping growth habit with erect branching is displayed. Good cold tolerance has been observed. The new cultivar is well suited for use as an improved attractive low-growing ornamental ground cover.

Abstract: A new and distinct variety of Clematis plant is provided that is the product of a controlled breeding program. Attractive purple flowers are formed on a substantially continuous basis over an extended period of time. The growth habit is compact and bushy and the plant well resists wilting and withering. The plant can be readily propagated by the use of cuttings and can be grown to advantage to provide colorful ornamentation in the landscape and in pots.

Abstract: A new and distinct cultivar of Forsythia plant is provided that is a seedling formed following the induced mutation of the ‘Spring Glory’ cultivar (non-patented in the United States). Gamma radiation was utilized to create the mutation. The new cultivar can be readily distinguished from the parent cultivar by the presence of a wide prostrate slow-growing growth habit. Anthocyanin coloration is present at the apex of the sepals. Attractive wide-opening yellow flowers are formed commonly on a single basis with one flower being formed per bud. The winter hardiness is good. The new cultivar also is well suited for growing as attractive ornamentation in the landscape where good control of plant height is to be maintained. The new cultivar requires no special care.

Abstract: A new and distinct Pachystegia insignis plant is provided that displays in profusion attractive sterile composite flowers having pure white ray florets and yellow disc florets. The overall growth habit is bushy. Dense greyed-green foliage is formed. The new cultivar is well suited for providing attractive ornamentation in the gardens where the climate is moderate. Alternatively, the cultivar can be grown in pots or other containers indoors.

The new cultivar can be readily distinguished from its parent by a more upright and more uniform growth habit, darker green foliage, more intense violet-blue flowers, and shorter internodes.

Abstract: A new and distinct Hydrangea plant is provided that was formed in the course of a planned breeding program. The plant is well-branched and displays a climbing growth habit. Attractive semi-persistent to persistent foliage is formed. Both large sterile and fertile flowers are exhibited. The plant can be grown to advantage where an attractive climbing ornamental plant is desired.

Abstract: A new and distinct variety of Forsythia plant named Courtasol is provided. The new variety was discovered among the open-pollination progeny growing in a cultivated area of a fertile mutant that was created by subjecting Forsythia.times.intermedia Spring Glory to gamma rays. Unlike its parent the new variety exhibits a distinctive low-growing, compact and spreading growth habit. Short internode lengths make possible a dense and abundant display of bright yellow blossoms in the springtime. A mature plant commonly assumes a height of approximately 0.5 meter and a width of approximately 1.2 meter. The new variety is particularly suited for growing as attractive ornamentation in the landscape.

Abstract: A new and distinct variety of Clematis plant is provided that is the product of a controlled breeding program. Attractive light lavender flowers with flashes of magenta along the central portion of each tepal are formed on a substantially continuous basis over an extended period of time. The growth habit is compact and bushy and the plant well resists wilting and withering. The plant can be readily propagated by the use of cuttings and can be grown to advantage to provide colorful ornamentation in the landscape and in pots.
