USPP15921P2 - Agastache plant named ‘After Eight’ - Google Patents

Abstract

A new and distinct cultivar of Agastache plant named ‘After Eight’, characterized by its upright, mounded and compact plant habit; freely flowering habit with numerous spikes per plant and numerous flowers per spike; and violet blue-colored flowers.

Description

Botanical classification/cultivar designation: Agastache rugosa×Agastache foeniculum cultivar After Eight.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Agastache plant, botanically known as Agastache rugosa×Agastache foeniculum, and hereinafter referred to by the name ‘After Eight’.

The new Agastache is a product of a planned breeding program conducted by the Inventor in Suameer, The Netherlands. The new Agastache was discovered and selected by the Inventor in a seed bed of sown Agastache seed from various cross-pollinations of unnamed Agastache rugosa seedling selections, not patented, with unnamed Agastache foeniculum seedling selections, not patented, in a controlled environment in Suameer, The Netherlands in 1996. The new Agastache was selected as an individual seedling within the progeny of these various cross-pollinations on the basis of its violet blue-colored flowers.

Asexual reproduction of the new cultivar by vegetative cuttings at Suameer, The Netherlands, 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 After Eight have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment 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 ‘After Eight’. These characteristics in combination distinguish ‘After Eight’ as a new and distinct Agastache cultivar:

• • 1. Upright, mounded and compact plant habit.
  • 2. Freely flowering habit with numerous spikes per plant and numerous flowers per spike.
  • 3. Violet blue-colored flowers.

Plants of the new Agastache are similar to plants of the parent selections. Compared to plants of the parent selections, plants of the new Agastache are more compact, have deeper violet blue flower coloration, and flower for a longer period of time.

Plants of the new Agastache can also be compared to plants of the Agastache cultivar Blue Fortune, not patented. Compared to plants of the cultivar Blue Fortune, plants of the new Agastache are more compact, flower for a longer period of time and have darker violet blue-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, 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 actual colors of the new Agastache.

The photograph on the right side of the sheet comprises a side perspective view of a typical flowering plant of ‘After Eight’ grown in a outdoor nursery.

The photograph on the left side of the sheet is a close-up view of typical flowering spikes of ‘After Eight’.
