1. A new and distinct Elaeagnus plant having the following combination of characteristics: (a) displays an upright and dense growth habit, (b) forms attractive variegated green leaves that are irregularly margined with yellow, and (c) is well suited for providing attractive ornamentation in the landscape; substantially as illustrated and described.
Botanical/commercial classification: Elaeagnus×ebbingei/Elaeagnus Plant.
Varietal denomination: cv. Viveleg.
SUMMARY OF THE INVENTION
Elaeagnus×ebbingei is recognized to be an attractive shrub which is believed to have originated in Holland. Such plant is capable of providing ornamentation in the landscape.
The new Elaeagnus plant of the present invention was discovered in a plant nursery at Toulouse, France, while growing among common Elaeagnus×ebbingei plants (non-patented in the United States). The new cultivar of the present is believed to be a whole plant mutation of unknown causation. I was primarily attracted to a single plant of the present invention in view of its attractive variegated leaves. Had I not discovered and preserved this plant, it would have been lost to mankind.
The new cultivar has been carefully preserved and has been evaluated in order to confirm its distinctive characteristics.
It was found that the new Elaeagnus plant displays the following combination of characteristics:
-
- (a) displays an upright and dense growth habit,
- (b) forms attractive variegated green leaves that are irregularly margined with yellow, and
- (c) is well suited for providing attractive ornamentation in the landscape.
The new cultivar can be grown to advantage in parks, gardens, and residential settings where a distinctive ornamental shrub is desired.
The new cultivar can be readily distinguished from common Elaeagnus ebbingei plants in view of the unusual appearance of the foliage. For example, the common plants of the species display leaves that are of a solid green coloration unlike the variegated green margined with yellow leaves of the new cultivar of the present invention. The new cultivar further can be readily distinguished from the ‘Gilt Edge’ cultivar (non-patented in the United States) which also displays leaves having a variegated coloration. More specifically, the new cultivar is considerably more vigorous, displays a more upright growth habit, and forms leaves wherein the upper surfaces are darker green in coloration and are irregularly margined with darker yellow.
Asexual reproduction of the new cultivar by the use of cuttings has been carried out at Toulouse, France. Such propagation has confirmed that the unique combination of characteristics of the new cultivar has been stably established and is well transmitted to successive generations. The new cultivar asexually reproduces in a true-to-type manner.
The new cultivar has been named ‘Viveleg’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs show as nearly true as it is reasonably possible to make the same in a color illustration of this character, typical mature plants of the new cultivar at an age of approximately five years while being grown outdoors in the landscape at Toulouse, France.
FIG. 1 shows a whole plant of the new cultivar while displaying the upright and dense growth habit.
FIG. 2 shows a close view of the distinctive variegated green foliage of new cultivar wherein the green leaves are irregularly margined with yellow.
DETAILED DESCRIPTION
The following is a detailed description of the new cultivar of the present invention which was prepared while observing mature plants at an age of approximately five years growing outdoors in the landscape during the summer at Toulouse, France. Color terminology is in accordance with the R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except when general color terms are used which are to be accorded their customary dictionary significance.

- Fragrance.— Strong and similar to that of Hyacinth and green lemon.
- Lastingness.— Commonly approximately one month.
- Color.— Near White Group 155C.
- Drupe.— Commonly near Red Group 39A, and approximately 1 cm in diameter on average.
-
- Development:
-
- Disease tolerance/resistance.— No disease problem has been observed during observations to date.
- Resistance to cold.— Has withstood temperatures as low as −15° C.
- Resistance to heat.— Has withstood temperatures as high as 45° C.
-
The new cultivar has not been observed under all possible environmental condition to date. Accordingly, it is possible that the phenotype may vary somewhat with variation in the environment, such as temperature, light intensity, day length, and other cultural conditions without variance of the genotype.
