Abstract

A new cultivar of Agapanthus plant, ‘Noagcar’, that is characterized by its vigorous growth habit, its immature peduncles that are strongly tinged with black prior to the opening of the flowers, its flowers that are violet-blue in color with a dark longitudinal stripe, and its floriferous blooming habit.

Description

Botanical classification: Agapanthus africanus.

Varietal denomination: ‘Noagcar’.

CROSS-REFERENCE TO A RELATED APPLICATION

This application claims priority to European Community Plant Variety Office (CPVO) Plant Breeder's Rights Application No. 2019/2216 filed on Sep. 11, 2019 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 Agapanthus africanus and will be referred to hereafter by its cultivar name, ‘Noagcar’. ‘Noagcar’ represents a new perennial grown for landscape use.

The new cultivar arose from an ongoing breeding program by the Inventor in Voorhout, The Netherlands. The objective of the breeding program was to develop a new cultivar of Agapanthus with a floriferous blooming habit and large flowers. The new cultivar arose from open pollination in August of 2012 of an unnamed and unpatented proprietary plant of Agapanthus africanus. The area contained numerous plants of unnamed and unpatented proprietary plants of Agapanthus africanus as a source of pollen; the exact male parent is therefore unknown. ‘Noagcar’ was selected as a single unique plant from the resulting seedlings in August of 2014.

Asexual propagation of the new cultivar was first accomplished by division in Voorhout, The Netherlands in September of 2016 under the direction of the Inventor. Asexual propagation by division and tissue culture using meristematic tissue has determined that the characteristics of this cultivar have been determined to be 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 ‘Noagcar’ as a distinct cultivar of Agapanthus.

- 1. ‘Noagcar’ exhibits a vigorous growth habit.
- 2. ‘Noagcar’ exhibits immature peduncles that are strongly tinged with black prior to the opening of the flowers.
- 3. ‘Noagcar’ exhibits flowers that are violet-blue in color with a dark longitudinal stripe.
- 4. ‘Noagcar’ exhibits a floriferous blooming habit.

The seed parent of ‘Noagcar’ differs from ‘Noagcar’ in having immature peduncles that are green in color and in producing less inflorescences when a young plant. ‘Noagcar’ can be most closely compared to the Agapanthus cultivars ‘Senna’ (U.S. Plant Pat. No. 19,972) and ‘Back in Black’ (not patented). ‘Senna’ and ‘Back in Black’ are both similar to ‘Noagcar’ in having peduncles that are black in color. ‘Senna’ differs from ‘Noagcar’ in having flowers that are slightly lighter and more purple in color, peduncles that retain their black coloration when the flowers open, and a shorter plant height. ‘Back in Black’ differs from ‘Noagcar’ in having flowers that are darker and much more purple in color, peduncles that retain their black coloration when the flowers open, and a shorter plant height.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Agapanthus. The photographs were taken of a 4-year-old plant of ‘Noagcar’ as grown outdoors in a 23-cm container in Warmond, The Netherlands.

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

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

The photograph in FIG. 3 provides a close-up view of the foliage of ‘Noagcar’.

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
