Agastache plant named ‘AGA 404’

Abstract

A new and distinct cultivar of Agastache plant named ‘AGA 404’, characterized by its compact, upright, outwardly spreading and open plant habit; freely branching habit; relatively large and dense inflorescences with small violet-colored flowers; freely and continuous flowering habit; and good garden performance.

Description

Botanical designation: Agastache hybrida.

Cultivar denomination: ‘AGA 404’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Agastache, botanically known as Agastache hybrida and hereinafter referred to by the same ‘AGA 404’.

The new Agastache is a product of a planned breeding program conducted by the Inventor in Hann. Münden, Germany. The objective of the breeding program was to create new Agastache cultivars with large and dense inflorescences and attractive flower coloration.

The new Agastache originated from an open-pollination during the summer of 2003 in Hann. Münden, Germany, of an unnamed selection of Agastache hybrida, not patented, as the female, or seed, parent with an unknown selection of Agastache hybrida as the male, or pollen, parent. The new Agastache was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated open-pollination in a controlled environment in Hann. Münden, Germany during the summer of 2004.

Asexual reproduction of the new Agastache by vegetative cuttings in a controlled environment in Hann. Münden, Germany during the winter of 2004, has shown that the unique features of this new Agastache are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar AGA 404 has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices 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 ‘AGA 404’. These characteristics in combination distinguish ‘AGA 404’ as a new and distinct cultivar of Agastache:

• • 1. Compact, upright, outwardly spreading and open plant habit.
  • 2. Freely branching habit.
  • 3. Relatively large and dense inflorescences with small violet-colored flowers.
  • 4. Freely and continuous flowering habit.
  • 5. Good garden performance.

Compared to plants of the female parent selection, plants of the new Agastache are more compact and differ in flower coloration.

Plants of the new Agastache can also be compared to plants of the cultivar Honey Bee Blue, not patented. In side-by-side comparisons conducted in Hann. Münden, Germany, plants of the new Agastache and the cultivar Honey Bee Blue differed in the following characteristics:

• • 1. Plants of the new Agastache had smaller leaves than plants of the cultivar Honey Bee Blue.
  • 2. Plants of the new Agastache had larger inflorescences than plants of the cultivar Honey Bee Blue.
  • 3. Plants of the new Agastache and the cultivar Honey Bee Blue differed in flower color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Agastache, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Agastache.

The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘AGA 404’ grown in a container.

The photograph at the top of the sheet is a close-up view of typical inflorescences and inflorescence buds of ‘AGA 404’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in Loudon, N.H. during the winter and under commercial practice in a glass-covered greenhouse. During the production of the plants, day temperatures ranged from 20° C. to 22° C. and night temperatures ranged from 18° C. to 20° C. After planting, plants were pinched one time. Plants had been growing for about ten weeks when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
