Description

Botanical designation: Agastache hybrida.

Cultivar denomination: ‘G19131’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Agastache plant, botanically known as Agastache hybrida, commonly referred to as Giant Hyssop or Hummingbird Mint and hereinafter referred to by the name ‘G19131’.

The new Agastache plant is a product of a planned breeding program conducted by the Inventor in Bellefonte, Pennsylvania. The objective of the breeding program is to create new compact and dense Agastache plants with good summer performance and winter hardiness.

The new Agastache plant originated from a self-pollination in Bellefonte, Pennsylvania during the summer of 2018 of a proprietary selection of Agastache hybrida identified as code number 50867-1, not patented. The new Agastache plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated self-pollination in a controlled environment in Bellefonte, Pennsylvania in August, 2019.

Asexual reproduction of the new cultivar by vegetative cuttings in a controlled environment in Bellefonte, Pennsylvania since August, 2019 has shown that the unique features of this new Agastache plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Agastache have not been observed under all possible combinations of 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 ‘G19131’. These characteristics in combination distinguish ‘G19131’ as a new and distinct Agastache plant:

• • 1. Relatively compact, broadly upright to somewhat outwardly spreading plant habit.
  • 2. Vigorous growth habit and rapid growth rate.
  • 3. Freely branching habit; dense and bushy appearance.
  • 4. Dark green-colored leaves.
  • 5. Freely flowering habit.
  • 6 Compact and dense inflorescences with numerous coral red-colored flowers.
  • 7. Good garden performance.

Plants of the new Agastache can be compared to plants of the parent selection. In side-by-side comparisons, plants of the new Agastache differ primarily from plants of the parent selection in the following characteristics:

• • 1. Plants of the new Agastache are more vigorous than plants of the parent selection.
  • 2. Plants of the new Agastache flower slightly later than plants of the parent selection.
  • 3. Flowers of plants of the new Agastache are darker coral red in color than flowers of plants of the parent selection.
  • 4. Plants of the new Agastache have not been observed to produce seeds whereas plants of the parent selection have been observed to produce seeds.

Plants of the new Agastache can be compared to plants of Agastache spp. ‘Rosie Posie’, disclosed in U.S. Pat. No. 25,857. In side-by-side comparisons, plants of the new Agastache differ primarily from plants of ‘Rosie Posie’ in the following characteristics:

• • 1. Plants of the new Agastache are more compact than plants of ‘Rosie Posie’.
  • 2. Plants of the new Agastache are more freely branching and denser than plants of ‘Rosie Posie’.
  • 3. Plants of the new Agastache flower three to five days earlier than plants of ‘Rosie Posie’.
  • 4. Flowers of plants of the new Agastache are lighter coral red in color than flowers of plants of ‘Rosie Posie’.
  • 5. Plants of the new Agastache have not been observed to produce seeds whereas plants of ‘Rosie Posie’ have been observed to produce seeds.

Plants of the new Agastache can also be compared to plants of Agastache hybrid ‘Kudos Coral’, disclosed in U.S. Pat. No. 25,613. In side-by-side comparisons, plants of the new Agastache differ primarily from plants of ‘Kudos Coral’ in the following characteristics:

• • 1. Plants of the new Agastache are more vigorous than plants of ‘Kudos Coral’.
  • 2. Plants of the new Agastache flower three to five days later than plants of ‘Kudos Coral’.
  • 3. Flowers of plants of the new Agastache are coral red in color whereas flowers of plants of ‘Kudos Coral’ are more coral orange in color.
  • 4. Plants of the new Agastache have not been observed to produce seeds whereas plants of ‘Kudos Coral’ have been observed to produce seeds.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the late winter and early spring in 10.75-cm containers in a glass-covered greenhouse in Loudon, New Hampshire and under cultural practices typical of commercial Agastache production. During the production of the plants, day and night temperatures averaged 20° C. Plants were eight weeks from planting rooted young plants when the photographs and description were taken.
