plant named ‘Kerviodeep’

A new and distinct Viola×wittrockiana cultivar named ‘KERVIODEEP’ is disclosed, characterized, by a unique combination of a large, round “pansy” type flower, found on a trailing plant. Flower color is a deep red. Plants have a compact, trailing plant habit. The new variety is a Viola×wittrockiana, suitable for outdoor landscape and container use.

Description

Latin name of the genus and species: Viola×wittrockiana.

Variety denomination: ‘KERVIODEEP’.

BACKGROUND OF THE INVENTION

The new cultivar is the product of a planned breeding program under the direction of the inventors, David Kerley, Priscilla Kerley and Timothy Kerley, all citizens of the United Kingdom. The objective of the breeding program was to produce new trailing Viola×wittrockiana cultivars for commercial ornamental purposes. The new cultivar resulted from the crossing of two unpatented proprietary seedlings. The seed parent was referred to as ‘05-66-4’ and the pollen parent was referred to as ‘05-66-5’. The cross resulting in ‘KERVIODEEP’ was performed during May of 2005. The selection of the new variety ‘Kerviodeep’ was made in April 2006, by the inventors at a research greenhouse located in Cambridge, UK.

Asexual reproduction of the new cultivar ‘KERVIODEEP’ by vegetative cuttings was first performed at the same research greenhouse in Cambridge, UK in July of 2006, and has shown that the unique features of this cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘KERVIODEEP’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘KERVIODEEP’ These characteristics in combination distinguish ‘KERVIODEEP’ as a new and distinct Viola cultivar:

    • 1. Unique round “pansy” flower, on a trailing Viola plant, rather than the elongated flower form more commonly found on spreading or trailing types which are usually Viola×williamsii.
    • 2. Large flower.
    • 3. Spreading, trailing plant habit.
    • 4. Exceptionally compact habit when grown in a small pot.
    • 5. Unique red flower color not found on trailing type Viola plants.

PARENT COMPARISON

Plants of the new cultivar ‘KERVIODEEP’ are similar to plants of the seed parent variety, in most horticultural characteristics. However, plants of the new cultivar produce larger flowers, of a more red color, whereas the seed parent has purple-red flowers. Additionally, the new variety produces flowers with a more round shape.

Plants of the new cultivar ‘KERVIODEEP’ are similar to plants of the pollen parent variety, in most horticultural characteristics. However, plants of the new cultivar produce larger flowers, of a more red color, whereas the pollen parent has purple-red flowers. Additionally, the new variety produces flowers with a more round shape.

COMMERCIAL COMPARISON

Through reasonable research, the inventors have been unable to identify any similar vegetatively propagated commercial Viola varieties, with red flower coloration to compare with ‘KERVIODEEP’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color typical plants of ‘KERVIODEEP’ grown in a poly house in Cambridge, UK. Plants are approximately 35 weeks old shown in a 20 cm basket, 3 rooted cuttings were planted per pot.

FIG. 2 illustrates a close up of a typical flower of ‘KERVOIDEEP’. The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
