Abstract

A new and distinct Viola×wittrockiana cultivar named ‘KERVIOPRISE’ is disclosed, characterized, by a unique combination of a large, round “pansy” type flower, found on a trailing plant. Flower color is white, flushed with violet color. 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: ‘KERVIOPRISE’.
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 an open pollination crossing the unpatented proprietary seed parent, referred to as ‘05-32-1’ and unknown proprietary pollen varieties. The exact date of the cross resulting in ‘KERVIOPRISE’ is unknown, but most likely during 2005. The selection of the new variety ‘Kervioprise’ was made in April 2006, by the inventors at a research greenhouse located in Cambridge, UK.
Asexual reproduction of the new cultivar ‘KERVIOPRISE’ 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 ‘KERVIOPRISE’ 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 ‘KERVIOPRISE’ These characteristics in combination distinguish ‘KERVIOPRISE’ 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. White flower color with Violet tones.
PARENT COMPARISON
Plants of the new cultivar ‘KERVIOPRISE’ are similar to plants of the seed parent variety, in most horticultural characteristics. However, plants of the new cultivar produce larger flowers, of a white coloration, with violet tones, whereas the seed parent has purple flowers. Additionally, the new variety produces a plant with a more trailing habit than the seed parent, and somewhat undulating, rather than frilly flower petals.
Plants of the new cultivar ‘KERVIOPRISE’ cannot be compared to the pollen parent, as a result of the open pollination, the pollen parent is not known.
COMMERCIAL COMPARISON
Plants of the new cultivar ‘KERVIOPRISE’ are similar to plants of the commercial variety known as Viola ‘Sunviolaho’ U.S. Plant Pat. No. 17,677, in some horticultural characteristics. However, plants of the new cultivar ‘KERVIOPRISE’ produce a larger, rounder flower, with some undulation to the petals, rather than flat petals. Additionally, the new variety has shorter peduncles, and Violet coloration in the upper petal not found in ‘Sunviolaho’.
Plant of ‘KERVIOPRISE’ can also be compared to the commercial variety Viola ‘Flovelwh’ U.S. Plant Pat. No. 20,762. Plants are similar in most horticultural characteristics, however, ‘KERVIOPRISE’ produces a larger flower, with a more trailing plant habit. Additionally, plants of ‘KERVIOPRISE’ produce flowers with a Violet coloration to the upper petal, not found in ‘Flovelwh’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photograph in FIG. 1 illustrates in full color typical plants of ‘KERVIOPRISE’ 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 ‘KERVOIPRISE’. The photographs were taken using conventional 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 ‘KERVOIPRISE’. 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.
 DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 except where general terms of ordinary dictionary significance are used.
