Abstract

A new and distinct Dianthus cultivar named ‘DCARE11-0’ is disclosed, characterized by continuous flowering on floriferous plants hardy to USDA Zone 3. Flowers are semi-double and uniquely true red. The new variety is a Dianthus, typically produced as a garden or container plant.

Description

Latin name of the genus and species: Dianthus hybrida.

Variety denomination: ‘DCARE11-0’.

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 the unpatented parent Dianthus ‘Magical Cherry’. ‘DCARE11-0’ was discovered by the inventor, Steve Jones, at a commercial greenhouse in Santa Paula, Calif. during April of 2016.

Asexual reproduction of the new cultivar ‘DCARE11-0’ was first performed in Santa Paula, Calif. at a commercial greenhouse by terminal vegetative cuttings in May of 2016. ‘DCARE11-0’ 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 ‘DCARE11-0’ 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 ‘DCARE11-0’. These characteristics in combination distinguish ‘DCARE11-0’ as a new and distinct Dianthus cultivar:

- 1. Floriferous plants.
- 2. Suitability for both garden and container uses.
- 3. Distinctive true red flower.
- 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 18 to 25 petals.

Plants of the new cultivar ‘DCAMC10-0’ are comparable to parent ‘Magical Cherry’ in most horticultural characteristics. However, the new variety ‘DCARE11-0’ differs in the following:

- 1. The new variety produces flowers colored Red (46B) with a white base. The seed parent produces flowers which are Red-Purple with a white base.
- 2. Plants of the new variety are more floriferous than plants of the seed parent.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘DCARE11-0’ are comparable to the commercial Dianthus variety ‘DCACR08-0’, U.S. Plant Pat. No. 30,026. The two Dianthus varieties are similar in most horticultural characteristics; however, the new variety ‘DCARE11-0’ produces a flower with a true red flower color, this comparator produces a medium pink to purple colored flower.

Plants of the new cultivar ‘DCARE11-0’ can also be compared to the commercial Dianthus variety ‘DDTHP02-0’, U.S. Plant Pat. No. 28,102. These varieties are similar in most horticultural characteristics; however ‘DCARE11-0’ produces a true red flower, compared to the lighter purple flower of this comparator.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘DCARE11-0’ grown outdoors in Santa Paula, Calif. This plant is approximately 20 weeks old, shown in a 1 gallon pot.

FIG. 2 illustrates a close up view of the flowers. 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.

DETAILED BOTANICAL DESCRIPTION
