plant named ‘HDLE105’

Abstract

A new and distinct cultivar of Dahlia plant named ‘HDLE105’, characterized by its compact, mounding and dense plant habit; serrated dark-colored leaves; freely flowering habit; daisy-type inflorescence form; large inflorescences with light yellow-colored ray florets; and good postproduction longevity.

Description

Botanical designation: Dahlia hybrida.

Cultivar denomination: ‘HDLE105’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Dahlia plant, botanically known as Dahlia hybrida, and hereinafter referred to by the name ‘HDLE105’.

The new Dahlia plant is a product of a planned breeding program conducted by the Inventor in Lisse, The Netherlands. The objective of the breeding program is to create new compact container Dahlia plants that have dark-colored leaves, large inflorescences and good postproduction longevity.

The new Dahlia plant originated from an open-pollination in Lisse, The Netherlands in 2009 of a proprietary seedling selection of Dahlia hybrida identified as code number VD5-272, not patented, as the female, or seed, parent with an unknown selection of Dahlia hybrida as the male, or pollen, parent. The new Dahlia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination in a controlled greenhouse environment in Lisse, The Netherlands in 2010.

Asexual reproduction of the new Dahlia plant by cuttings since the spring of 2011 in a controlled greenhouse environment in Lisse, The Netherlands, has shown that the unique features of this new Dahlia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Dahlia have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature 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 ‘HDLE105’. These characteristics in combination distinguish ‘HDLE105’ as a new and distinct Dahlia plant:

• • 1. Compact, mounding and dense plant habit.
  • 2. Serrated dark-colored leaves.
  • 3. Freely flowering habit.
  • 4. Daisy-type inflorescence form.
  • 5. Large inflorescences with light yellow-colored ray florets.
  • 6. Good postproduction longevity.

Plants of the new Dahlia differ primarily from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Dahlia are more compact and denser than plants of the female parent selection.
  • 2. Leaves of plants of the new Dahlia are darker in color than leaves of plants of the female parent selection.
  • 3. Plants of the new Dahlia and the female parent selection differ in ray floret color as plants of the female parent selection have reddish brown-colored ray florets.

Plants of the new Dahlia can be compared to plants of the Dahlia hybrida ‘HDW79’, disclosed in U.S. Plant Pat. No. 23,298. In side-by-side comparisons conducted in Lisse, The Netherlands, plants of the new Dahlia differed from plants of ‘HDW79’ in the following characteristics:

• • 1. Plants of the new Dahlia were taller and broader than plants of ‘HDW79’.
  • 2. Plants of the new Dahlia were more freely branching and denser than plants of ‘HDW79’.
  • 3. Plants of the new Dahlia had thicker stems than plants of ‘HDW79’.
  • 4. Leaves of plants of the new Dahlia were lighter in color than leaves of plants of ‘HDW79’.
  • 5. Plants of the new Dahlia had larger inflorescences than plants of ‘HDW79’.
  • 6. Plants of the new Dahlia were more freely flowering than plants of ‘HDW79’.
  • 7. Plants of the new Dahlia and ‘HDW79’ differed in ray floret color as plants of ‘HDW79’ had white-colored ray florets.

DETAILED BOTANICAL DESCRIPTION

The photographs and following observations and measurements describe plants grown during the summer and autumn in ground beds in an outdoor nursery in Lisse, The Netherlands and under cultural practices typical of commercial Dahlia production. During the production of the plants, day temperatures ranged from 10° C. to 25° C. and night temperatures ranged from 5° C. to 20° C. Plants were pinched one time about three weeks after planting. Plants were 14 weeks old when the photographs and description were taken.
