Description

Description

Botanical denomination: Dianthus hybrid.

Cultivar designation: ‘Dragon Fruit’.

BACKGROUND OF THE INVENTION

The present invention relates to the new and distinct cultivar of Dianthus or Pinks from the genus Dianthus and given the cultivar name ‘Dragon Fruit’. The new plant was the result of an intentional cross in May of 2006 by Kevin A. Hurd between ‘Double Spotty’ U.S. Plant Pat. No. 13,884 as the seed parent and ‘Devon Siskin’ U.S. Plant Pat. No. 14,377 (more often known as ‘Raspberry Swirl’) as the pollen parent. The new hybrid was first isolated from trials at a nursery in Zeeland, Mich. during the summer of 2007. Dianthus ‘Dragon Fruit” has been asexually propagated at the same nursery in Zeeland, Mich. using traditional shoot tip cutting procedures and found to reproduce plants that are identical and exhibit all the characteristics of the original plant.

SUMMARY OF THE INVENTION

The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment including: growing temperature, available sunlight, nutrients, water, etc. without a change in the genotype of the plant. The new plant is distinct from its parents and all other Dianthus known to the applicant in the following combined traits:

- 1. Double flowers with high petal counts.
- 2. Unique floral color and pattern.
- 3. High heat tolerance.
- 4. Floriferous habit.
- 5. Vigorous growth and excellent habit.
- 6. Compact, distinctly blue-green foliage.

FIG. 2 shows a close-up of the flower and bud.

FIG. 3 shows the dissected flower of the new plant together with capsule and seeds.

DETAILED DESCRIPTION OF THE PLANT

The following detailed description of the new plant is based on observations of several two-year old plants in open-field, full-sun conditions in Zeeland, Mich. with supplemental watering, light additions of fertilizer and free of other plant growth regulators. All color usage is in reference to the 2001 edition of The Royal Horticultural Colour Chart except where common dictionary terms are used.
