Abstract

A new cultivar of Viola plant named ‘SMEV3’ that is distinguishable by compact dome-shaped habit, fragrant bi-colored flowers consisting of mauve-pink upper petals and yellow lateral and lower petals which exhibit prominent dark violet veins. ‘SMEV3’ is hardy in USDA Zone 5 and blooms from early spring through fall.

Description

Latin name of the genus and species: Viola hybrida.

Denomination: ‘SMEV3’.

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 ‘SMEV3’.

‘SMEV3’ 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 colors borne on plants with a uniform dense domed habit. The breeding program commenced in 2001.

‘SMEV3’ is a hybrid seedling selection that resulted from the controlled cross-pollination in December 2006 of the female parent, Viola ‘Tiger Eyes’ (non-patented) and the male parent, Viola ‘Lord Primrose’ (U.S. Plant Pat. No. 18,253). The resulting seed was collected, sown and raised to flowering during 2007. From an approximate 150 seedlings, ten were selected by the inventor, and then propagated asexually by cuttings. From these ten, ‘SMEV3’ was selected in March 2008 based on the criteria of novel flower color and prolific flower number.

‘SMEV3’ is distinguishable from each of its parents by flower color as follows. The flowers of ‘SMEV3’ are bi-colored, consisting of mauve-pink upper petals and yellow lateral and lower petals. In addition, the lateral and lower petals of ‘SMEV3’ exhibit prominent dark violet veins. The flowers of the female parent are golden yellow throughout except for dark brown to black central blotch and radiating veins. The flowers of the male parent are bi-colored, predominantly mauve with small yellow centers and absence of dark blotch or veins.

The closest comparison plant in commerce known to the inventor is the male parent, Viola ‘Lord Primrose’, with which ‘SMEV3’ is compared above.

The first asexual reproduction of ‘SMEV3’ was accomplished in 2008 in a cultivated area of Victoria, Australia. Asexual propagation was accomplished by the inventor, using the method, of vegetative cuttings. Since that time ‘SMEV3’ 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 ‘SMEV3’. These traits in combination distinguish ‘SMEV3’ from all other existing varieties of Viola known to the inventor. ‘SMEV3’ 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. ‘SMEV3’ exhibits compact dome-shaped habit.
- 2. ‘SMEV3’ exhibits green glossy foliage.
- 3. ‘SMEV3’ produces numerous flowers on short peduncles.
- 4. The flowers of ‘SMEV3’ are bi-colored, consisting of mauve-pink upper petals and yellow lateral and lower petals.
- 5. The lateral and lower petals of ‘SMEV3’ exhibit prominent dark violet veins.
- 6. The flowers of ‘SMEV3’ are pleasantly fragrant with the characteristic perfume of violets.
- 7. After one year of growth from a rooted cutting ‘SMEV3’ is 20 cm. in height including the flowers, and 20 cm. in width.
- 8. ‘SMEV3’ is hardy in USDA Zone 5.
- 9. ‘SMEV3’ blooms from early spring through fall.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color drawings illustrate the overall appearance of the new Viola cultivar named ‘SMEV3’ 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 ‘SMEV3’. Both drawings were made from a plant which has been grown in an unheated greenhouse in Arroyo Grande, Calif. 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. Below is s a description of each of the figures:

FIG. 2 depicts a close-up view of a flower on the plant shown in FIG. 1.

BOTANICAL DESCRIPTION OF THE PLANT
