plant named ‘AMBIC001’

Abstract

A new cultivar of Agapanthus named ‘AMBIC001’, that is characterized by its inflorescences that form moderately dense umbels of bicolor flowers that are white with a dark blue base, its semi-deciduous plant habit, its vigorous growth habit with fast sucker production, its long flowering period, and its good cold hardiness.

Description

Botanical classification: Agapanthus hybrid.

Varietal denomination: ‘AMBIC001’.

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, ‘AMBIC001’. ‘AMBIC001’ represents a new perennial herb grown for landscape use.

The new cultivar was derived from a controlled breeding program by the Inventor in Linbro Park, Johannesburg, South Africa. The Inventor made a cross in 2006 between unnamed plants from the Inventors' breeding program. The female and male parents were siblings produced by crossing unnamed plants of Agapanthus praecox subsp. orientalis and Agapanthus campanulatus. The Inventor selected ‘AMBIC001’ in July of 2008 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 the Inventor in Linbro Park, Johannesburg, South Africa in 2009. Asexual propagation by division 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 ‘AMBIC001’ as a distinct cultivar of Agapanthus.

• • 1. ‘AMBIC001’ exhibits inflorescences that form moderately dense umbels of bicolor flowers that are white with a dark blue base.
  • 2. ‘AMBIC001’ exhibits a semi-deciduous plant habit.
  • 3. ‘AMBIC001’ exhibits a long flowering period.
  • 4. ‘AMBIC001’ exhibits a vigorous growth habit with fast sucker production.
  • 5. ‘AMBIC001’ exhibits good cold hardiness.
    The parent plants of ‘AMBIC001’, Agapanthus praecox subsp. orientalis×Agapanthus campanulatus hybrids, both differ from ‘AMBIC001’ in having a slower growth rate, shorter flowering period, and sparser umbels and in being larger in size. ‘AMBIC001’ can be most closely compared to the cultivars ‘Queen Mum’ (not patented) and ‘Cloudy Days’ (not patented). ‘Queen Mum’ differs from ‘AMBIC001’ in being much larger in size and in having an evergreen plant habit, a slower growth rate, a slower production rate of suckers and in being less cold hardy. ‘Cloudy Days’ differs from ‘AMBIC001’ in being slightly larger in size less cold hardy and in having an evergreen plant habit, a slower growth rate, a slower production rate of suckers.

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 3 month-old plants of ‘AMBIC001’as grown (from a rooted tissue culture liner) outdoors in a 9-cm circular container in Oldtown, Republic of Ireland.

The photograph in FIG. 1 provides a view of a plant of ‘AMBIC001’ in bloom.

The photograph in FIG. 2 provides a close-up view of an inflorescence of ‘AMBIC001’.

The photograph in FIG. 3 provides a close-up view of the foliage of ‘AMBIC001’.

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
