Agastache plant named ‘Kiegabi’

Abstract

A distinct cultivar of Agastache plant named ‘Kiegabi’, characterized by its upright, outwardly spreading and open plant habit; freely basal branching growth habit; numerous salmon pink-colored flowers that become light purple with development positioned close together on erect flowering spikes; and good garden performance.

Description

Botanical classification/cultivar designation: Agastache mexicana cultivar Kiegabi.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Agastache plant, botanically known as Agastache mexicana, commercially known as Hyssop, and hereinafter referred to by the name ‘Kiegabi’.

The new Agastache is a product of a planned breeding program conducted by the Inventor in Venhuizen, The Netherlands. The objective of the breeding program is to create new Agastaches with improved plant habit and flowering characteristics and attractive flower coloration.

The new Agastache originated from a cross-pollination made by the Inventor in 2001 of a proprietary seedling selection of Agastache mexicana identified as code number 97(1020), not patented, as the female, or seed parent, with a proprietary seedling selection of Agastache mexicana identified as code number 97(0014-1), not patented, as the male, or pollen parent. The new Agastache was selected as a single plant from the resulting progeny of the cross-pollination by the Inventor in a controlled environment in Venhuizen, The Netherlands.

Asexual reproduction of the new cultivar by cuttings taken in a controlled environment in Venhuizen, The Netherlands since 2001, has shown that the unique features of this new Agastache are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Kiegabi have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and culture 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 ‘Kiegabi’. These characteristics in combination distinguish ‘Kiegabi’ as a new and distinct cultivar of Agastache:

• • 1. Upright, outwardly spreading and open plant habit.
  • 2. Freely basal branching growth habit.
  • 3. Numerous salmon pink-colored flowers that become light purple with development positioned close together on erect flowering spikes.
  • 4. Good garden performance.

In side-by-side comparisons conducted in Venhuizen, The Netherlands, plants of the new Agastache differed primarily from plants of the female parent selection in flower color.

In side-by-side comparisons conducted in Venhuizen, The Netherlands, plants of the new Agastache differed from plants of the male parent selection primarily in flower color as plants of the male parent selection had salmon pink-colored flowers.

Plants of the new Agastache can be compared to plants of the cultivar Champagne, not patented. In side-by-side comparisons conducted in Venhuizen, The Netherlands, plants of the new Agastache and the cultivar Champagne differed in the following characteristics:

• • 1. Plants of the new Agastache had darker green-colored foliage than plants of the cultivar Champagne.
  • 2. Plants of the new Agastache and the cultivar Champagne differed in flower color as plants of the cultivar Champagne had pink orange-colored flowers.
