Latin name of the genus and species: Dianthus hybrida.
Variety denomination: ‘DCAPE04-0’.
BACKGROUND OF THE INVENTION
The new cultivar is a product of chance discovery. The new variety originated as a spontaneous whole plant mutation discovered among a commercial planting of mixed Dianthus hybrida varieties. The parent is unknown. ‘DCAPE04-0’ was discovered by the inventor, Steve Jones, at a commercial greenhouse in Santa Paula, Calif. during Summer of 2014.
Asexual reproduction of the new cultivar ‘DCAPE04-0’ was first performed in Santa Paula, Calif. at a commercial greenhouse by vegetative cuttings in Summer of 2014. ‘DCAPE04-0’ has since produced several generations and has shown that the unique features of this cultivar are stable and reproduced true to type.
SUMMARY OF THE INVENTION
The cultivar ‘DCAPE04-0’ 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 ‘DCAPE04-0’. These characteristics in combination distinguish ‘DCAPE04-0’ as a new and distinct Dianthus cultivar:
- 1. Floriferous plants.
- 2. Suitability for both garden and container uses.
- 3. Pastel pink flower colored near Red-Purple 70C and Purple 75D with a white base.
- 4. Continuous flowering from Spring through Fall. Repeat flowering enhanced by removal of spent flowers.
- 5. Hardy to USDA zone 3
- 6. Semi-double flower with an average of 14 to 20 petals.
COMMERCIAL COMPARISON
Plants of the new cultivar ‘DCAPE04-0’ are comparable to the unpatented, commercial Dianthus variety ‘Constant Beauty Light Pink’. The two Dianthus varieties are similar in most horticultural characteristics; however, the new variety ‘DCAPE04-0’ produces a flower with a different red-purple color, mainly darker and having less purple tones. Flowers of the new variety also have a more consistent color within the same flower.
Plants of the new cultivar ‘DCAPE04-0’ can also be compared to the commercial Dianthus variety ‘DDTHP02-0’ having U.S. Plant Pat. No. 28,102. These varieties are similar in most horticultural characteristics; however ‘DCAPE04-0’ produces a red-purple flower, compared to the purple flower of this comparator.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photograph illustrates in full color a typical plant of ‘DCAPE04-0’ grown outdoors in Santa Paula, Calif. This plant is approximately 17 weeks old, shown in a 6 inch pot. The photograph was 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.
