Abstract
A new and distinct cultivar of Rhododendron plant named ‘Angelina’, characterized by its uniform, upright and outwardly spreading plant habit; dark green foliage; numerous showy double hose-in-hose white-colored flowers; and long flowering period.
Description
The present invention relates to a new and distinct cultivar of Rhododendron, botanically known as Rhododendron simsii and hereinafter referred to by the name ‘Angelina’.
The new Rhododendron is a product of a planned breeding program conducted by the Inventor in Lochristi, Belgium. The objective of the breeding program is to create new long-flowering Rhododendron cultivars.
The new Rhododendron originated from a cross made by the Inventor in 1990 in Lochristi, Belgium, of two unidentified proprietary seedling selections of Rhododendron simsii.
The new Rhododendron was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Lochristi, Belgium. The selection of this plant was based on its double white flowers.
Asexual reproduction of the new Rhododendron by terminal cuttings taken in a controlled environment in Lochristi, Belgium, has shown that the unique features of this new Rhododendron are stable and reproduced true to type in successive generations.
The new Rhododendron has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, light intensity, nutritional 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 ‘Angelina’. These characteristics in combination distinguish ‘Angelina’ as a new and distinct cultivar:
1. Uniform, upright and outwardly spreading plant habit.
2. Dark green foliage.
3. Numerous showy double hose-in-hose white-colored flowers.
4. Long flowering period; plants stay in flower for about 30 days.
Plants of the new Rhododendron can be compared to plants of the single-flowered cultivar ‘Aline’, not patented. However, in side-by-side comparisons conducted in Lochristi, Belgium, plants of the new Rhododendron are more vigorous, have more uniform branching habit, and have longer lasting flowers than plants of the cultivar ‘Aline’.
The accompanying colored photographs illustrate the overall appearance of the new Rhododendron, showing 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 Rhododendron.
The photograph at the top of the sheet comprises a side perspective view of a typical plant of ‘Angelina’.
The photograph at the bottom of the sheet is a close-up view of typical flowers of ‘Angelina’. Plants in the photographs were about two years old.
The aforementioned and following observations, measurements, values, and comparisons describe plants grown in Lochristi, Belgium, in an outdoor nursery in 17-cm containers under conditions which approximate commercial Rhododendron production conditions. Plants were grown for about 2 years with day temperatures averaging 18° C. and night temperatures averaging 10° C. Plants were pinched about 5 times during the production of these plants. In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
