USPP19882P2 - Viola plant named ‘SMEV1’ - Google Patents

Abstract

A new cultivar of Viola named ‘SMEV1’ that is distinguishable by compact habit, green glossy foliage, and large fragrant, blue and cream-white flowers. In combination these traits set ‘SMEV1’ apart from all other existing varieties of Viola known to the inventor.

Description

Genus: VIOLA.

Species: ×hybrida.

Denomination ‘SMEV1’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of violet grown for use in borders, containers, and the landscape. The new invention from the family Violaceae, is known botanically as Viola×hybrida and will be referred to hereinafter by the cultivar name ‘SMEV1’.

The new Viola cultivar named ‘SMEV1’ resulted from a formal breeding program developed by the inventor and conducted in Wonga Park, Victoria, Australia. Goals of the breeding program were to produce a range of heat tolerant, perennial Viola exhibiting a range of flower color. The program was started in 2001. The inventor conducted deliberate controlled cross-pollination in October 2002. The seedlings that resulted from this cross were grown to maturity. Five seedlings were selected, asexually reproduced and grown to maturity for another two generations. From the final generation the inventor selected ‘SMEV1’ in September 2004, based on the criteria of flower size and flower color.

‘SMEV1’ is a selected hybrid seedling that resulted from cross-pollination of Viola ‘Etain’ (female parent, unpatented) and Viola ‘Painted Porcelain’ (male parent, unpatented). The new Viola cultivar named ‘SMEV1’ is distinguishable from the parents by a band of blue color that “bleeds” into a large area of the petal blade, onto a predominantly cream-white background. The flower of Viola ‘Etain’ exhibits a fine lavender edge on petals, with a yellow center. The flower of ‘Painted Porcelain’ has mauve venation spreading throughout petals and varying in color depth throughout season.

The distinguishing characteristics of ‘SMEV1’ are compact habit, glossy green foliage, large perfume-scented flowers held on short peduncles, with blue-margined flower color on a predominantly cream-white petal background. Mature dimensions are 20 cm. in height and 40 cm. in width. Cultural requirements include full sun to filtered light, moist organic soil, and regular water. Hardy to USDA Zone 5 and blooms early winter through spring.

The first asexual reproduction of ‘SMEV1’ was accomplished in 2004, by the inventor in a cultivated area of Victoria, Australia. The method used was softwood cuttings. Since that time ‘SMEV1’ has been determined stable and true to type in subsequent generations of asexual propagation.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the distinguishing characteristics of the new Viola cultivar named ‘SMEV1’. These traits in combination distinguish ‘SMEV1’ from all other existing varieties of Viola known to the inventor. ‘SMEV1’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.

• • 1. ‘SMEV1’ exhibits compact dome-shaped habit.
  • 2. ‘SMEV1’ exhibits green glossy foliage.
  • 3. ‘SMEV1’ exhibits large perfume-scented flowers on short peduncles.
  • 4. ‘SMEV1’ exhibits blue-margined and cream-white flowers.
  • 5. ‘SMEV1’ is 20 cm. in height and 40 cm. in width.
  • 6. ‘SMEV1’ is hardy to USDA Zone 5.
  • 7. ‘SMEV1’ blooms spring through fall.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color drawings illustrate the overall appearance of the new Viola cultivar named ‘SMEV1’ showing color as true as is reasonably possible to obtain in color reproductions of this type. Color in the drawings may differ from the color values cited in the detailed botanical description, which accurately describe the actual color of the new variety ‘SMEV1’. Drawings were made in December 2007 of plants grown under glass in 1-liter containers.

The drawing labeled FIG. 1 depicts the entire plant in bloom.

The drawing labeled FIG. 2 depicts a close-up view of the flower.

Drawings were made using conventional techniques and although flower and foliage color may appear different from actual color due to light reflectance, they are as accurate as possible by conventional photography.
