USPP35644P2 - Agapanthus plant named ‘DWAgHyb01’ - Google Patents

Abstract

A new cultivar of Agapanthus plant named ‘DWAgHyb01’ that is characterized by its long flowering period with good re-blooming, its high quantity of flowers per umbel that are vividly dark blue in color, its good resistance to root and crown rot, and its medium plant height (70 to 80 cm).

Description

Botanical classification: Agapanthus hybrid.

Varietal denomination: ‘DWAgHyb01’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to European Community Plant Variety Office (CPVO) Plant Breeder's Rights Application No. 2022/2143 filed Sep. 23, 2022. The Applicant received the information for the Plant breeders' rights application directly from the Inventor. This application is also 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 ‘DWAgHyb02’ (U.S. Plant patent application Ser. No. 18/112,907).

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, ‘DWAgHyb01’. ‘DWAgHyb01’ 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, North West Province, South Africa. The goal of the breeding program was to develop a new cultivar of Agapanthus with large sized inflorescences that are dark blue in color, resistance to crown rot, and a reblooming habit. The Inventor 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 ‘DWAgHyb01’ in November 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, North West 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 ‘DWAgHyb01’ as a distinct cultivar of Agapanthus.

• • 1. ‘DWAgHyb01’ exhibits a long flowering period with good re-blooming.
  • 2. ‘DWAgHyb01’ exhibits a high quantity of flowers per umbel that are vividly dark blue in color.
  • 3. ‘DWAgHyb01’ exhibits good resistance to root and crown rot.
  • 4. ‘DWAgHyb01’ exhibits a medium plant height (70 to 80 cm).

The female parent of ‘DWAgHyb01’ differs from ‘DWAgHyb01’ in having flowers that are lighter in color and in having a slower growth habit. The male parent of ‘DWAgHyb01’ differs from ‘DWAgHyb01’ in having flowers that are lighter in color and in having a faster growth habit. ‘DWAgHyb01’ can be most closely compared to the Agapanthus cultivars ‘Black Pantha’ (not patented), ‘Sbd002’ (U.S. Plant Pat. No. 30,164 P2) and ‘DWAgHyb02’. ‘Black Pantha’ is similar to ‘DWAgHyb01’ in having flowers that are blue in color. ‘Black Pantha’ differs from ‘DWAgHyb01’ in having flowers that are lighter blue and less uniform in color with more purple tones on the inside of the tepals, a less vigorous growth habit, and in lacking a re-blooming habit. ‘Sbd002’ is similar to ‘DWAgHyb01’ in having a high quantity of flowers per umbel that are blue in color. ‘Sbd002’ differs from ‘DWAgHyb01’ in having flowers that are lighter blue in color, inflorescences that are smaller in size and foliage that is less grey in color. ‘DWAgHyb02’ differs from ‘DWAgHyb01’ in having flowers that are more purple in color, a slightly more compact plant habit, a more vigorous growth habit, and less reblooming.

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, Crocus, De Witt Plant Breeders (youtube), Thompson and Morgan, Peter van Rijssen (linkedin), Perfect Garden, Hoogeveen Plants, Fairweather' s Nursery, Plant Lust, Bali-Hai Nursery (ebay), Oz Planten, Plant Estate, Spijker and Lichtnelke.

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 2 years in age of ‘DWAgHyb01’ 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 ‘DWAgHyb01’ in bloom.

The photograph in FIG. 2 provides a close-up view of an inflorescence of ‘DWAgHyb01’.

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.
