USPP18731P2 - Myrica plant named ‘Soleil ’ - Google Patents

Abstract

A new cultivar of Myrica plant named ‘SOLEIL’ that is characterized by densely branched, brilliant yellow foliage. In combination these traits set ‘SOLEIL’ apart from all other exiting varieties of Myrica known to the inventor.

Description

Genus: Myrica.

Species: cerifera.

Denomination: SOLEIL.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Myrica or wax myrtle that is grown for use as an ornamental evergreen shrub or small tree. It is known botanically as Myrica cerifera and will be referred to hereinafter by the cultivar name ‘SOLEIL’.

‘SOLEIL’ is the product of a breeding program started by the inventor in 1992 in a cultivated area of Raleigh, N.C. The primary focus of the breeding program is to produce new cultivars of shrubs and trees with attractive foliage.

‘SOLEIL’ was selected in 1994 as a single seedling from a large population of seedlings which the inventor had grown from seed collected from pollination of the inventor's large collection of Myrica. The inventor is unable to identify either the male or the female parent.

‘SOLEIL’ exhibits brilliant yellow foliage. There are no known comparable cultivars known to the inventor. There are varieties that are unique for dwarfness or cut leaves including Myrica ‘Georgia Gem’ (U.S. Plant Pat. No. 6,411) and Myrica ‘Lane’ (U.S. Plant Pat. No. 7,555), but these do not exhibit the bright gold-yellow leaf color of ‘Soleil’.

Asexual reproduction of the new cultivar was first accomplished by the inventor in 1994 in a cultivated area of Raleigh, N.C. The method of asexual propagation used was softwood cuttings. Since that time the characteristics of the new cultivar have been determined stable and are reproduced true to type in successive generations by asexual propagation.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new Myrica cultivar ‘SOLEIL’. These traits in combination distinguish ‘SOLEIL’ from all other varieties of Myrica known to the inventor. ‘SOLEIL’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic and cultural conditions, without however any change in genotype.

• • 1. Myrica ‘SOLEIL’ exhibits a densely branched shrub, round in shape.
  • 2. Myrica ‘SOLEIL’ exhibits brilliant yellow foliage.
  • 3. Myrica ‘SOLEIL’ is 2 m in height and 3 m in wide at 7 years.
  • 4. Myrica ‘SOLEIL’ blooms in late April.
  • 5. Myrica ‘SOLEIL’ is hardy to USDA Hardiness Zone 7.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color drawings illustrate the overall appearance of the new Myrica variety ‘SOLEIL’ showing colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the drawings may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety ‘SOLEIL’.

FIG. 1 shows a six year old plant of ‘Soleil’ which has been established in the landscape in North Carolina. The photograph was taken in mid June and shows the golden foliage of ‘Soleil’ unaffected by high summer temperatures and light.

FIG. 2 shows a two year old plant of ‘Soleil’ which is growing in a 3 gallon container. The plant has been grown in a frost-free greenhouse and the photograph was taken in May.

FIG. 3 shows a close up view of the foliage of ‘Soleil’.

All drawings were made using conventional techniques and although colors may appear different from actual colors due to light reflectance they are as accurate as possible by conventional photography.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new cultivar ‘SOLEIL’. Data was collected from plants grown in out of doors in Raleigh, N.C. The color determinations are in accordance with the 2001 edition of The Royal Horticultural Society Colour Chart of the Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used. No chemicals were used to treat the plants. Growing conditions are typical to other Myrica.
