plant named ‘Hanneke’

Abstract

A new cultivar of Agapanthus named ‘Hanneke’, characterized by its mid to late season blooming habit, its full flower heads of dark purple flowers that are held semi pendulous from pedicels, its tall plant height, and its usefulness as a cut flower for its long stems.

Description

Botanical classification: Agapanthus praecox.

Varietal denomination: ‘Hanneke’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Agapanthus praecox and will be referred to hereafter by its cultivar name, ‘Hanneke’. ‘Hanneke’ represents a new perennial herb grown for landscape and cut flower use.

The new Agapanthus originated as the result of an on going breeding program in Cape Town, Republic of South Africa. The goal of the breeding program was to produce a cultivar of Agapanthus that is tall in height and useful as a cut flower.

‘Hanneke’ originated as a seedling that arose from seed planted from open pollination of an unnamed plant of Agapanthus praecox from the Inventor's breeding program in 2002. The male parent is unknown. The new Agapanthus was selected as a single unique plant in December of 2004.

Asexual propagation of the new cultivar was first accomplished by in vitro propagation under the direction of the Inventor in December of 2005 in Cape Town, Republic of South Africa. Asexual propagation by division and 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. The characteristics in combination distinguish ‘Hanneke’ as a distinct cultivar of Agapanthus.

• • 1. ‘Hanneke’ exhibits a mid to late season blooming habit.
  • 2. ‘Hanneke’ exhibits full flower heads of dark purple flowers that are held semi pendulous from pedicels.
  • 3. ‘Hanneke’ exhibits a tall plant height.
  • 4. ‘Hanneke’ is useful as a cut flower for its long stems.

The female parent differs from ‘Hanneke’ in having flowers that are lighter in color, in blooming earlier, and in having a shorter plant height. ‘Hanneke’ can be compared to the cultivars ‘Peter Pan’ (not patented) and ‘Snowball’ (not patented). ‘Peter Pan’ is similar to ‘Hanneke’ in being evergreen and in flower form, but ‘Peter Pan’ differs from ‘Hanneke’ in being shorter in plant height with shorter stems, and in having flowers that are blue in color. ‘Snowball’ is similar to ‘Hanneke’ in being evergreen and in having full flower heads. ‘Snowball’ differs from ‘Hanneke’ in having white flowers 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 three year-old plant of ‘Hanneke’ as field grown outdoors in Cape Town, Republic of South Africa.

The photograph in FIG. 1 provides a close-up view of an inflorescence of ‘Hanneke’.

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

DETAILED BOTANICAL DESCRIPTION

The general observations and descriptions describe plants about two year-old in age as grown outdoors under field conditions in Cape Town, Republic of South Africa. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determinations are in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
