USPP35591P2 - Agapanthus plant named ‘DWAghyb02’ - Google Patents

Abstract

A new cultivar of Agapanthus plant named ‘DWAgHyb02’ that is characterized by its good resistance to root and crown rot, its dense umbels of flowers that are dark purple in color opening from nearly black flower buds, its longer flowering period with light re-blooming, its fast growth habit, its medium height, and its high flower count per umbel.

Description

Botanical classification: Agapanthus hybrid.

Varietal denomination: ‘DWAgHyb02’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to European Community Plant Variety Office (CPVO) Plant Breeder's Rights Application No. 2022/2869, filed Dec. 7, 2022. The Applicant received the information for the Plant breeders' rights application directly from the Inventor. This application is co-pending with a U.S. Plant Patent Application filed for a plant derived from the same breeding program that is entitled Agapanthus Plant Named ‘DWAgHyb01’ (U.S. Plant patent application Ser. No. 18/112,983).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Agapanthus of hybrid origin and will be referred to hereafter by its cultivar name, ‘DWAgHyb02’. ‘DWAgHyb02’ represents a new perennial grown for landscape and container use.

The new cultivar was derived from a controlled breeding program by the Inventors in Hartebeespoort, Northwest Province, South Africa. The goal of the breeding program was to develop a new a cultivar of Agapanthus that re-blooms, has dark purple flowers, and is resistant to rot caused by Erwinia sp. The Inventors made a cross in October of 2015 between unnamed proprietary plants of Agapanthus from the Inventors' breeding program as both the female and male parents. The Inventors selected ‘DWAgHyb02’ in October of 2017 as a single unique plant amongst the seedlings that resulted from the above cross.

Asexual propagation of the new cultivar was first accomplished by division by one of the Inventors in Hartebeespoort, Northwest Province, South Africa in October of 2017. Asexual propagation by division and tissue culture utilizing meristematic tissue has determined that the characteristics of the new 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. The characteristics in combination distinguish ‘DWAgHyb02’ as a distinct cultivar of Agapanthus.

• 1. ‘DWAgHyb02’ exhibits good resistance to root and crown rot.
• 2. ‘DWAgHyb02’ exhibits dense umbels of flowers that are dark purple in color opening from nearly black flower buds.
• 3. ‘DWAgHyb02’ exhibits a longer flowering period with light re-blooming.
• 4. ‘DWAgHyb02’ exhibits a fast growth habit.
• 5. ‘DWAgHyb02’ exhibits a medium height.
• 6. ‘DWAgHyb02’ exhibits a high flower count per umbel.

The female parent of ‘DWAgHyb02’ differs from ‘DWAgHyb02’ in having flowers that are lighter in color. The male parent of ‘DWAgHyb02’ differs from ‘DWAgHyb02’ in having flowers that are lighter in color and a slower growth habit. ‘DWAgHyb02’ can be most closely compared to the Agapanthus cultivars ‘Black Magic’ (not patented), ‘DWAgHyb01’, and ‘Black Pantha’ (not patented). ‘Black Magic’ , ‘DWAgHyb01’, and ‘Black Pantha’ are all similar to ‘DWAgHyb02’ in having flowers that are dark in color. ‘Black Magic’ differs from ‘DWAgHyb02’ in having flowers that are slightly darker in color and a deciduous habit growth habit and in lacking a re-blooming habit. ‘DWAgHyb01’ differs from ‘DWAgHyb02’ in having flowers that are blue in color, a slightly less compact plant habit, a less vigorous growth habit, and less re-blooming. ‘Black Pantha’ differs from ‘DWAgHyb02’ in having flowers that are less intense in color, a less vigorous growth habit, and in a better re-blooming habit.

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 disclosures and/or sales that fall within a one-year grace period to the filing date. Disclosures include website listings by Planttipp, RHS Plants, Cowellsgc, Peter Planttipp (YouTube), Plantestate, Peter van Rijssen (linkedin), Fairweather's Nursery, CND Nursery, Globe Planter, and Crocus.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the overall appearance and distinct characteristics of the new Agapanthus. The photographs were taken of plants about 2 years in age of ‘DWAgHyb02’ as grown outdoors in a 30-cm container in Linbro Park, Johannesburg, South Africa.

The photograph in FIG. 1 provides a side view of a plant of ‘DWAgHyb02’ in bloom.

The photograph in FIG. 2 provides a close-up view of an inflorescence of ‘DWAgHyb02’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and color values cited in the detailed botanical description accurately describe the colors of the new Agapanthus.
