Description
Botanical designation: Rhododendron hybrida.
Cultivar denomination: ‘Spring Fling’.
The present Invention relates to a new and distinct cultivar of Azalea, botanically known as Rhododendron hybrida, an evergreen greenhouse-forcing type Azalea, and hereinafter referred to by the name ‘Spring Fling’.
The new Azalea 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 originated from a cross-pollination made by the Inventor in January, 1995, in Alva, Fla., of a proprietary Azalea selection identified as code number YB-0343, not patented, as the female, or seed, parent with a proprietary Azalea selection identified as code number YB-0995, not patented, as the male, or pollen, parent. The new Azalea was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Alva, Fla., in June, 1997.
Asexual reproduction of the new Azalea by terminal cuttings taken in a controlled environment in Alva, Fla. since September, 1997, has shown that the unique features of this new Azalea are stable and reproduced true to type in successive generations.
The new Azalea has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and/or light intensity without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Spring Fling’. These characteristics in combination distinguish ‘Spring Fling’ as a new and distinct cultivar:
-
- 1. Dark green-colored leaves that do not abscise during the cooling and forcing periods.
- 2. Uniform and outwardly spreading plant habit.
- 3. Freely branching habit.
- 4. Uniform and freely flowering habit.
- 5. Rapid flowering response; plants begin flowering about 20 days after cooling treatment.
- 6. Light pink-colored flowers with random red purple-colored and flecks.
- 7. Hose-in-hose flower form.
- 8. Excellent postproduction longevity with plants maintaining good flower substance for about 32 days in an interior environment.
In side-by-side comparisons conducted in Alva, Fla., plants of the new Azalea differed from plants of the female parent selection in the following characteristics:
-
- 1. Plants of the new Azalea had hose-in-hose flowers whereas plants of the female parent selection had single flowers.
- 2. Flowers of plants of the new Azalea were light pink in color with random red purple-colored spots and flecks whereas flowers of plants of the female parent selection had white and red bi-colored flowers.
In side-by-side comparisons conducted in Alva, Fla., plants of the new Azalea differed from plants of the male parent selection primarily in flower color as plants of the male parent selection had coral pink-colored flowers.
Plants of the new Azalea can be compared to the plants of the cultivar YB871 Remembrance, disclosed in U.S. Plant Pat. No. 9,132. However, in side-by-side comparisons conducted in Alva, Fla., plants of the new Azalea differed from plants of the cultivar YB871 Remembrance in the following characteristics:
-
- 1. Plants of the new Azalea were more vigorous than plants of the cultivar YB871 Remembrance.
- 2. Plants of the new Azalea flowered earlier after the cooling treatment than plants of the cultivar YB871 Remembrance.
- 3. Plants of the new Azalea and the cultivar YB871 Remembrance differed in flower coloration.
The accompanying colored photographs illustrate the overall appearance of the new Azalea. 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.
The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Spring Fling’.
The photograph on the second sheet is a close-up view of typical flowers and leaves of ‘Spring Fling’.
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 winter and early spring and under commercial production conditions. During the production of the plants, day temperatures ranged from 13 to 37° C. and night temperatures ranged from 0 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 to 5° C. for about 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 about one year old.
In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
