Abstract
A new cultivar of Prunus laurocerasus, ‘Nero’, characterized by its elongated dark green glossy mature leaves and young leaves that are yellow-green, bushy spreading mounded plant habit; reaching about 2 m in height and 3 m in width, its moderate growth rate, its good disease resistance, and its hardiness at least in U.S.D.A. Zones 6 to 9.
Description
Botanical classification: Prunus laurocerasus.
Variety denomination: ‘Nero’.
The present invention relates to a new and distinct cultivar of Prunus laurocerasus, and will be referred to hereafter by its cultivar name, ‘Nero’. ‘Nero’ is a new cultivar of cherry laurel grown for use as a landscape plant.
The new cultivar of Prunus, ‘Nero’, arose from an ongoing breeding program by the Inventor in Szombathely, Hungary. The new cultivar was selected as a naturally occurring whole plant mutation in summer of 2002 that arose from seeds collected, pooled and sown from open pollination of the cultivars ‘Mari’, ‘Piri’, and Klàri (all three not patented). The exact parenage is unknown.
Asexual propagation of the new cultivar was first accomplished by stem cuttings by the Inventor in Szombathely, Hungary in September of 2007. Asexual propagation by stem cuttings has determined that the characteristics of the new cultivar are stable and reproduced true to type in successive generations.
The following traits have been repeatedly observed and represent the characteristics of the new Prunus. These attributes in combination distinguish ‘Nero’ as a unique cultivar of Prunus.
-
- 1. ‘Nero’ exhibits elongated dark green glossy mature leaves and young leaves that are bronze-yellow.
- 2. ‘Nero’ exhibits a bushy spreading mounded plant habit; reaching about 2 m in height and 3 m in width.
- 3. ‘Nero’ exhibits a moderate growth rate.
- 4. ‘Nero’ exhibits good disease resistance.
- 5. ‘Nero’ exhibits good hardiness with hardiness at least in U.S.D.A. Zones 6 to 9.
‘Nero’ is unique and unlike any other cultivars of Prunus laurocerasus known to the Inventor. Possible parent plants; ‘Mari’, ‘Piri’, and Klàri, all differ from ‘Nero’ in lacking glossy leaves, and in having leaves that are less elongated. ‘Nero’ an be most closely compared to the cultivars ‘Caucasica’ (not patented) and ‘Otto Luyken’ (not patented). ‘Caucasica’ is similar to ‘Nero’ in foliage coloration, however ‘Caucasica’ differs from ‘Nero’ in having leaves that are less elongated and in having a more vigorous growth habit. ‘Otto Luyken’ is similar to ‘Nero’ in having glossy dark green mature leaves, but differs from ‘Nero’ in having a plant habit that is less dense and in not being as realiably cold hardy when grown under the same conditions.
The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new cultivar. The photographs were taken of 6 year-old plants as grown outdoors in a trial bed in Szombathely, Hungary.
The photograph in FIG. 1 illustrates the plant habit of ‘Nero’.
The photograph in FIG. 2 is a view of a row of plants of ‘Nero’.
The colors in the photographs are as close as possible with the digital photography techniques available, the color values cited in the detailed botanical description accurately describe the colors of the Prunus.
The following is a detailed description of 6 year-old trees of the new cultivar as grown outdoors in a trial bed in Szombathely, Hungary. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
