Abstract
A new and distinct Azalea cultivar named ‘ROBLEV’ is disclosed, characterized by distinctive solid white flowers. Plants are, globular, very compact and bloom throughout Spring, Summer and Fall. The new cultivar is a Azalea, suitable for ornamental garden purposes.
Description
Latin name of the genus and species: Azalea hybrid.
Variety denomination: ‘ROBLEV’.
The new cultivar is a product of chance discovery by the inventor. This new variety, hereinafter referred to as ‘ROBLEV’, was discovered as a branch sport by Flint Jerome Johnson, Jul. 23, 2005, in Loxley, Ala., at a commercial nursery. The parent variety producing this naturally occurring mutation is Azalea ‘Robled’ U.S. Plant Pat. No. 15,862.
After identifying the new variety as a potentially interesting selection, the inventor first organized propagation of ‘ROBLEV’ by vegetative cuttings on Jun. 2, 2006 at the same commercial nursery in Loxley, Ala. The inventor continued controlled testing and propagation, assessing stability of the unique characteristics of this variety. Multiple generations have been reproduced and have shown that the unique features of this cultivar are stable and reproduced true to type.
The cultivar ‘ROBLEV’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘ROBLEV’ These characteristics in combination distinguish ‘ROBLEV’ as a new and distinct Azalea cultivar:
-
- 1. The unique spring, summer, and fall blooming.
- 2. Solid white flowers
- 3. Easily propagated with semi-hardwood cuttings in late spring through the summer.
- 4. Good specimen plant.
- 5. Excellent performance in planters.
- 6. Very good foundation plant.
- 7. Does well as an understory plant in a woodland garden.
- 8. Hardy to Zone 7.
- 9. Attracts butterflies.
- 10. Very compact growth
- 11. Uniform, globular plant shape.
‘ROBLEV’ is similar in most horticultural characteristics to the parent variety Azalea hybrid ‘Robled’, U.S. Plant Pat. No. 15,862. Plants of the new cultivar ‘ROBLEV’ however, produce flowers that are white in coloration, compared to the pink flowers of the parent variety. Pedicel coloration is also different. Additionally, the mature plant height and spread of the new variety is less than that of the parent variety. Plant habit is overall more compact in the new variety, compared to the parent.

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘ROBLEV’ grown outdoors in Alabama. The plant is approximately 2 years old, and is shown in a three gallon container.
The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
In the following description, color references are made to The Royal Horticultural Society Colour Chart 2001 except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘ROBLEX’ plants grown outdoors in Loxley, Ala. Plants are approximately 2 years old, in a 3 gallon nursery container.
