A new and distinct cultivar of Azalea plant named ‘Jewel Box’, characterized by its dark green, glossy and broad leaves that do not abscise during the cooling and forcing periods; dense, upright and outwardly spreading plant habit; freely branching habit; uniform flowering response; numerous and showy dark pink and white bicolored flowers; hose-in-hose flower form; and excellent postproduction longevity with plants maintaining good flower substance for more than four weeks in an interior environment.
Description
The present Invention relates to a new and distinct cultivar of Azalea, botanically known as Rhododenfron hybrida, an evergreen greenhouse-forcing type Azalea, and hereinafter referred to by the name ‘Jewel Box’.
The new Azalea is a product of a planned breeding program conducted by the Inventor in Salinas, Calif. and Alva, Fla. The objective of the breeding program is to create new Azalea varieties having uniform plant habit, profuse and uniform flowering, 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 made by the Inventor in January, 1992, in Salinas, Calif., of the cultivar ‘Prize’ disclosed in U.S. Plant Pat. No. 3,795, as the female, or seed, parent with the cultivar ‘Marian Lee’, not patented, as the male, or pollen, parent. The new Azalez was descovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Alva, Fla., in June, 1994. The selection of this plant was based on its uniform and dense plant habit, hose-in-hose flower form, dark pink and white bicolored flower color, uniform flowering response, and excellent postproduction longevity.
Asexual reproduction of the new Azalea by terminal cuttings taken in a controlled environment in Alva, Fla., 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, light intensity, nutrition and water status without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Jewel Box’. These characteristics in combination distinguish ‘Jewel Box’ as a new and distinct cultivar:
1. Dark green, glossy and broad leaves that do not abscise during the cooling and forcing periods.
2. Dense, upright and outwardly spreading plant habit.
3. Freely branching habit.
4. Uniform flowering response.
5. Numerous and showy dark pink and white bicolored flowers.
6. Hose-in-hose flower form.
7. Excellent postproduction longevity with plants maintaining good flower substance for more than four weeks in an interior environment.
8. Very low incidence of infection with Cylindrocladium in inoculated trials.
Plants of the Azalea differ from plants of the female parent, the cultivar ‘Prize’, in the following characteristics:
1. Plants of the new Azalea have hose-in-hose flowers whereas plants of the cultivar ‘Prize’ have semi-double to double hose-in-hose flowers.
2. Plants of the new Azalea have dark pink and white bicolored flowers whereas plants of the cultivar ‘Prize’ have dark rose pink-colored flowers.
3. Plants of the new Azalea have longer postproduction longevity than plants of the cultivar ‘Prize’.
Plants of the new Azalea differ from plants of the male parent, the cultivar ‘Marian Lee’, in the following characteristics:
1. Plants of the new Azalea are denser and more uniform in plant habit than plants of the cultivar ‘Marian Lee’.
2. Plants of the new Azalea flower more uniformly than plants of the cultivar ‘Marian Lee’.
3. Plants of the new Azalea have hose-in-hose flowers whereas plants of the cultivar ‘Marian Lee’ have single flowers.
4. Plants of the new Azalea have dark pink and white bicolored flowers whereas plants of the cultivar ‘Marian Lee’ have red and white bicolored flowers.
Plants of the new Azalea can be compared to the plants of the cultivar ‘Parasol’, disclosed in U.S. Plant Pat. No. 11,152. However, in side-by-side comparsions conducted by the Inventor in Salinas, Calif., plants of the new Azalea differed from plants of the cultivar ‘Parasol’ in the following characteristics:
1. Plants of the new Azalea are more freely branching and have a more uniform plant habit than plants of the cultivar ‘Parasol’.
2. Plants of the new Azalea flower more profusely and uniformly than plants of the cultivar ‘Parasol’.
3. Plants of the new Azalea have dark pink and white bicolored flowers whereas plants of the cultivar ‘Parasol’ have hot pink and white bicolored flowers.
4. Plants of the new Azalea have longer postproduction longevity than plants of the cultivar ‘Parasol’.
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 actual colors of the new Azalea.
The photograph at the top of the sheet comprises a side perspective view of a typical plant of ‘Jewel Box’.
The photograph at the bottom of the sheet is a close up view of typical flowers of ‘Jewel Box’.
The aforementioned and following observations, measurements, values, and comparisons describe multiple plants grown in Salinas, Calfi., in 12.5-cm containers in greenhouses during the spring under commercial production conditions. After flower bud development, plants were cooled at 3 5° C. for four weeks to break flower bud dormancy. Plants were subsequently forced into flower under commercial production conditions in a greenhouse. Plants described were about one year old.
