USPP34999P2 - Hakonechloa plant named ‘Hakbri1’ - Google Patents

Abstract

A new and unique cultivar of Hakonechloa plant named ‘Hakbri1’ that is characterized by its variegated foliage that is chartreuse in color with yellow and creamy white stripes.

Description

Botanical classification: Hakonechloa macra.

Varietal designation: ‘Hakbri1’.

CROSS-REFERENCE TO A RELATED APPLICATION

This application claims priority to a Canadian Plant Breeder's Rights Application No. 22-10985 filed on Jun. 3, 2022, under 35 U.S.C. 119(f), the entire contents of which is incorporated by reference herein.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hakonechloa macra and will be referred to hereafter by its cultivar name, ‘Hakbri1’. ‘Hakbri1’ represents a new ornamental grass grown for landscape use.

The inventor discovered the new cultivar in spring of 2016 as a naturally occurring shoot mutation of Hakonechloa macra ‘All Gold’ (not patented) that was growing in a container in a production block in Elma, Wash.

Asexual propagation of the new cultivar was first accomplished by tissue culture using meristematic tissue in Elma, Wash. in 2017 by the Inventor. Asexual propagation by tissue culture has determined that the characteristics of this cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Hakbri1’ as a unique cultivar of Hakonechloa.

• • 1. ‘Hakbri1’ exhibits variegated foliage that is chartreuse in color with yellow and creamy white stripes.

The female is similar to ‘Hakbri1’ in having foliage that is chartreuse in color. The female parent differs from ‘Hakbri1’ in having darker colored foliage with no variegation. ‘Hakbri1’ can also be compared to the Hakonechloa macra cultivar ‘Aureola’ (not patented). ‘Aureola’ is similar to ‘Hakbri1’ in having variegated foliage. ‘Aureola’ differs from ‘Hakbri1’ in having foliage that is green with stripes of yellow.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR

The Applicant asserts that no publications or advertisements relating to sales, offers for sale, or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor. The Applicant claims a prior art exemption under 35 U.S.C. 102(b)(1) for disclosure and/or sales that fall within a one-year grace period to the filing date. Disclosures include website listings by Briggs Nursery and Babikow.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the overall appearance and distinct characteristics of the new Hakonechloa. The photographs in FIG. 1 and FIG. 2 were taken of a 3-year-old plant of ‘Hakbri1’ as grown outdoors in a C1 container in Elma, Wash.

The photograph in FIG. 1 provides a side view of ‘Hakbri1’.

The photograph in FIG. 2 provides a close-up view of the foliage of ‘Hakbri1’.

The photograph in FIG. 3 was taken of 1-year-old plants as grown in 128-cell liners in Elma, Wash. and provides a comparison between ‘All Gold’ (plants on left) ‘Hakbri1’ (plants on right).

The 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 Hakonechloa.
