Description
Botanical designation: Rhododendron hybrida.
Cultivar denomination: ‘YBAZ-2504’.
The present Invention relates to a new and distinct cultivar of Azalea plant, botanically known as Rhododendron hybrida, an evergreen greenhouse-forcing type Azalea, and hereinafter referred to by the name ‘YBAZ-2504’.
The new Azalea plant is a product of a planned breeding program conducted by the Inventor in Alva, Fla. The objective of the breeding program is to create new Azalea varieties having uniform plant habit, profuse and uniform flowering response, dark green foliage, good foliage retention during the cooling and forcing periods, resistance to Cylindrocladium and excellent postproduction longevity.
The new Azalea plant originated from a cross-pollination made by the Inventor in April, 1997, in Alva, Fla., of the Azalea ‘Sonnet’, disclosed in U.S. Plant Pat. No. 16,784, as the female, or seed, parent with the Azalea ‘Lavender Lace’, disclosed in U.S. Plant Pat. No. 11,137, as the male, or pollen, parent. The new Azalea was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Alva, Fla. in October, 2000.
Asexual reproduction of the new Azalea plant by terminal cuttings taken in a controlled environment in Alva, Fla. since January, 2001, has shown that the unique features of this new Azalea are stable and reproduced true to type in successive generations.
Plants of the new Azalea have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘YBAZ-2504’. These characteristics in combination distinguish ‘YBAZ-2504’ as a new and distinct Azalea cultivar:
-
- 1. Dark green-colored leaves that do not abscise during the cooling and forcing periods.
- 2. Uniform, outwardly spreading and mounding plant habit.
- 3 Freely branching habit.
- 4. Uniform and freely flowering habit.
- 5. Pink-colored flowers.
- 6. Double flower form.
- 7 Excellent postproduction longevity with plants maintaining good flower substance for about five weeks in an interior environment.
Plants of the new Azalea differ from plants of the female parent, ‘Sonnet’, in the following characteristics:
-
- 1. Plants of the new Azalea are more outwardly spreading than and not as upright as plants of ‘Sonnet’.
- 2. Plants of the new Azalea flower more uniformly than plants of ‘Sonnet’.
- 3. Flowers of plants of the new Azalea are pink in color whereas flowers of plants of ‘Sonnet’ are lavender in color.
Plants of the new Azalea differ from plants of the male parent, ‘Lavender Lace’, in the following characteristics:
-
- 1. Plants of the new Azalea have double flowers whereas plants of ‘Lavender Lace’ have single flowers.
- 2. Plants of the new Azalea have pink-colored flowers whereas plants of ‘Lavender Lace’ have lavender-colored flowers.
Plants of the new Azalea can be compared to the plants of ‘Party Favor’, disclosed in U.S. Plant Pat. No. 10,050. In side-by-side comparisons conducted in Alva, Fla., plants of the new Azalea differed from plants of ‘Party Favor’ in the following characteristics:
-
- 1. Plants of the new Azalea had stronger foliage than plants of ‘Party Favor’.
- 2. Plants of the new Azalea had double pink-colored flowers whereas plants of ‘Party Favor’ had semi-double dark pink-colored flowers.
The accompanying colored photographs illustrate the overall appearance of the new Azalea plant. These photographs show the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Azalea plant.
The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘YBAZ-2504’.
The photograph on the second sheet is a close-up view of a typical flower of ‘YBAZ-2504’.
The aforementioned photographs and following observations and measurements describe plants grown in Alva, Fla. with three plants per 15-cm containers, in a polypropylene-covered shade house during the late spring and under commercial production conditions. During the production of the plants, day temperatures ranged from 13° C. to 37° C. and night temperatures ranged from 0° C. to 26° C. Plants were pinched at planting, pinched a second time about twelve weeks later and then pinched a third time about twelve weeks after the second pinch. After sufficient flower bud development, plants were cooled at 3° C. to 5° C. for four weeks to break flower bud dormancy. Plants were subsequently forced into flower under commercial production conditions in a polyethylene-covered greenhouse. Plants used for the photographs and description were one year old. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
