plant named ‘DwAgHybPi’

Abstract

A new cultivar of Agapanthus plant named ‘DwAgHybPi’ that is characterized by its good resistance to root and crown rot, its high quantity of flowers per umbel, its flowers that are pink and white in color, its long flowering period with modest re-blooming, its medium plant height, and its evergreen growth habit.

Description

Botanical classification: Agapanthus hybrid.

Varietal denomination: ‘DwAgHybPi’.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to European Community Plant Variety Office (CPVO) Plant Breeder's Rights Application No. 2024/2201 filed on Sep. 19, 2024, under 35 U.S.C. 119(f), the entire contents of which is incorporated by reference herein. The Applicant received the information for the Plant breeders' rights application directly from the Inventors. 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 ‘DWAgHyb18’ (U.S. Plant patent application Ser. No. 18/910,392).

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, ‘DwAgHybPi’. ‘DwAgHybPi’ 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 a cultivar of Agapanthus with a long blooming period that re-blooms with pink flowers and is resistant to rot caused by Erwinia sp. The Inventors made a cross in November of 2016 between unnamed and unpatented proprietary plants of Agapanthus from the Inventors' breeding program as both the female and male parents. The Inventors selected ‘DwAgHybPi’ in November of 2020 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 2019. 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 ‘DwAgHybPi’ as a distinct cultivar of Agapanthus.

• 1. ‘DwAgHybPi’ exhibits good resistance to root and crown rot.
• 2. ‘DwAgHybPi’ exhibits a high quantity of flowers per umbel.
• 3. ‘DwAgHybPi’ exhibits flowers that are pink and white in color.
• 4. ‘DwAgHybPi’ exhibits a long flowering period with modest re-blooming.
• 5. ‘DwAgHybPi’ exhibits a medium plant height.
• 6. ‘DwAgHybPi’ exhibits an semi-evergreen growth habit.

The female parent of ‘DwAgHybPi’ differs from ‘DwAgHybPi’ in having flowers with less pink coloration. The male parent of ‘DwAgHybPi’ differs from ‘DwAgHybPi’ in having a larger plant size and broader leaves. ‘DwAgHybPi’ can be most closely compared to the Agapanthus cultivars ‘Strawberry Ice’ (not patented), ‘WP001’ (U.S. Plant Pat. No. 27,357), and ‘DWAgHyb18’. ‘Strawberry Ice’ differs from ‘DwAgHybPi’ in having white flowers that only have pink coloration when the flowers age. ‘WP001’ differs from ‘DwAgHybPi’ in having flowers that are white in color and a slower growth habit. ‘DWAgHyb18’ is similar to ‘DWAgHybPi’ in having disease resistance, in having a reblooming habit, and a semi-evergreen growth habit. ‘DWAgHyb18’ differs from ‘DWAgHybPi’ in having white and green flowers.

Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventors. 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 Dobies, CND Nursery, Van Meuwen, Sprint Horticulture, R.H.S. Plants, Crocus, Grows on You, Thompson & Morgan, Waitrose Garden, and Suttons Seeds.

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 a plant 1 year in age as grown outdoors in a 19-cm container in Hartebeespoort, North West Province, South Africa.

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

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

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.
