Description

Latin name of the genus and species: Dianthus hybrid.

Variety denomination: ‘DDTBW13-0’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a planned breeding program. The new variety originated as the result of the crossing of the female parent, an unpatented, proprietary Dianthus referred to as ‘13-307-001’.and the pollen parent, a different unpatented proprietary Dianthus referred to as ‘13-130-002’. The crossing was made during July 2017 at a commercial greenhouse in Santa Paula, Calif. ‘DDTBW13-0’ was discovered and selected at a commercial greenhouse in Santa Paula, Calif., in December of 2018.

Asexual reproduction of the new cultivar ‘DDTBW13-0’ was first performed in Santa Paula, Calif. at a research greenhouse by vegetative terminal cuttings in January of 2019. ‘DDTBW13-0’ 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 ‘DDTBW13-0’ 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 ‘DDTBW13-0’. These characteristics in combination distinguish ‘DDTBW13-0’ as a new and distinct Dianthus cultivar:

    • 1. Unique burgundy colored flowers with a distinct white margin on the petals.
    • 2. Early flowering.
    • 3. Suitability for both garden and container uses.
    • 4. Extended bloom time into Summer and Fall months.
    • 5. Hardy to USDA Zone 5.

PARENTAL COMPARISON

Plants of the new cultivar ‘DDTBW13-0’ are comparable to the seed parent in most horticultural characteristics; however, the new variety ‘DDTBW13-0’ differs in the following:

    • 1. Plants of the new variety are more compact than plants of the seed parent.

Plants of the new cultivar ‘DDTBW13-0’ are comparable to the pollen parent in most horticultural characteristics; however, the new variety ‘DDTBW13-0’ differs in the following:

    • 1. The new variety produces multi-whorled flowers, the pollen parent produces single flowers.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘DDTBW13-0’ are comparable to the commercial Dianthus variety ‘DDTHP02-0’, U.S. Plant Pat. No. 28,102. The two Dianthus varieties are similar in most horticultural characteristics; however, the new variety ‘DDTBW13-0’ differs in the following:

    • 1. The new variety produces bi-color burgundy and white flowers while this comparator has solid pink flowers.
    • 2. Foliage of the new variety is longer and narrower than foliage of this comparator.
    • 3. Plants of the new variety are on average 2.5 cm taller than plants of this comparator.

Plants of the new cultivar ‘DDTBW13-0’ 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 ‘DDTBW13-0’ differs in the following:

    • 1. The new variety produces bi-color burgundy and white flowers while this comparator has solid dark pink flowers.
    • 2. Foliage of the new variety is brighter green than foliage of this comparator.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘DDTBW13-0’ in a greenhouse in Santa Paula, Calif. This plant are approximately 12 weeks old, grown in a 6 inch pot.

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

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.
