Abstract

A new cultivar of Viola named ‘SMEV2’ that is distinguishable by compact dome-shaped habit, green glossy foliage, and large soft yellow flowers. In combination these traits set ‘SMEV2’ apart from all other existing varieties of Viola known to the inventor.

Description

Genus: VIOLA.

Species: ×hybrida.

Denomination: ‘SMEV2’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of VIOLA known commonly as violet and grown for use in border, container, and landscape. The new invention from the family Violaceae is known botanically as VIOLA×hybrida and will be referred to hereinafter by the cultivar name ‘SMEV2’.

‘SMEV2’ resulted from a formal breeding program developed by the inventor, and conducted in Wonga Park, Victoria, Australia with the goal of producing a series of perennial Viola exhibiting a range of flower color. The breeding program commenced in 2002.

‘SMEV2’ is a hybrid seedling selection that resulted from controlled cross-pollination of the female parent, Viola ‘Lord Primrose’ (U.S. Plant Pat. No. 18,253) and the male parent, Viola ‘Painted Porcelain’ (non-patented). Seed was collected and sown in early 2005 and raised to flowering. From an approximate 150 seedlings, five were selected by the inventor, and then propagated asexually, by cuttings. From these ‘SMEV2’ was selected in 2005 based on the criteria of habit, flower dimensions, flower color, and prolific flower number.

The closest comparison plants known to the inventor are the two parent varieties, ‘Lord Primrose’ and ‘Painted Porcelain’. ‘SMEV2’ is distinguishable from both parents by flower color. Whereas the flowers of ‘SMEV2’ are solid yellow in color, the flowers of ‘Lady Primrose’ are predominantly violet in color and exhibit a mid-yellow blotch or eye; and the flowers of ‘Painted Porcelain’ are light violet in color and exhibit a dark violet blotch or eye.

The unique traits exhibited by ‘SMEV2’ are compact dome-shaped habit, glossy green foliage, and numerous large scented flowers that are soft yellow in color, and held on short peduncles. Blooming occurs spring through fall. After six months of growth from a rooted cutting the dimensions of ‘SMEV2’ are 20 cm. in height and 20 cm. in width. Cultural requirements include shade to filtered sunlight, moist organic soil, and regular water. ‘SMEV2’ is hardy in USDA Zone 5.

The first asexual reproduction of ‘SMEV2’ was accomplished in 2005 in a cultivated area of Victoria, Australia. Asexual propagation was accomplished by the inventor, using the method, of softwood cuttings. Since that time ‘SMEV2’ 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 ‘SMEV2’. These traits in combination distinguish ‘SMEV2’ from all other existing varieties of Viola known to the inventor. ‘SMEV2’ 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. ‘SMEV2’ exhibits compact dome-shaped habit.
  • 2. ‘SMEV2’ exhibits green glossy foliage.
  • 3. ‘SMEV2’ produces numerous large flowers on short peduncles.
  • 4. The flowers of ‘SMEV2’ are soft yellow in color, slightly fading towards the outer petal margins.
  • 5. The flowers of ‘SMEV2’ are pleasantly fragrant with the characteristic perfume of violets.
  • 6. After one year of growth from a rooted cutting ‘SMEV2’ is 20 cm. in height including the flowers, and 20 cm. in width.
  • 7. ‘SMEV2’ is hardy in USDA Zone 5.
  • 8. ‘SMEV2’ blooms spring through fall.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color drawings illustrate the overall appearance of the new Viola cultivar named ‘SMEV2’ 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 ‘SMEV2’.

The drawing labeled FIG. 1 depicts a 3 months plant in first bloom, grown in a 10 cm. container.

The drawing labeled FIG. 2 depicts a close-up view of the flowers on the plant shown in FIG. 1.

Both drawings were made from a plant which has been grown in a well-ventilated unheated greenhouse in Victoria, Australia. No pinching or chemical growth regulators have been employed.

Both 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.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed botanical description of the new Viola cultivar named ‘SMEV2’. Observations and measurements were collected in Arroyo Grande, Calif. during the month of July from a two months old plant, grown from an unrooted cutting, and in its first flower. The observed plant was grown out of doors in a 6 cm liner pot. Color determinations were made in accordance with The 2001 Royal Horticultural Society Colour Chart from London, England, except where general color terms of ordinary dictionary significance are used.
