Abstract

A new cultivar of Agapanthus, ‘MP003’, that is characterized by flowers that are vivid purple in color, its fast growth habit, its extended blooming period with re-bloom throughout the year, and its good resistance to root and crown rot caused by Fusarium sp. and soft rot caused by Erwinia sp.

Description

Botanical classification: Agapanthus hybrid.

Varietal denomination: ‘MP003’.

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, ‘MP003’. ‘MP003’ represents a new perennial grown for landscape use.

The new cultivar was derived from a controlled breeding program by the Inventor in Hartebeespoort, Northwest Province, South Africa. The objective of the breeding program was to develop a new cultivar of Agapanthus that had a more compact pant habit combined with purple flowers and a vigorous growth habit. The Inventor made a cross in November of 2008 between unnamed proprietary plants of Agapanthus from the Inventor's breeding program as both the female parent and male parent. The Inventor selected ‘MP003’ in November of 2012 (first selected in 2010 for further evaluation) 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 Hartebeespoort, Northwest Province, South Africa in January of 2013. Asexual propagation by division and tissue culture 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 ‘MP003’ as a distinct cultivar of Agapanthus.

- 1. ‘MP003’ exhibits flowers that are vivid purple in color.
- 2. ‘MP003’ exhibits a fast growth habit.
- 3. ‘MP003’ exhibits an extended blooming period with re-bloom throughout the year.
- 4. ‘MP003’ exhibits good resistance to root and crown rot caused by Fusarium sp. and soft rot caused by Erwinia sp.

The female parent of ‘MP003’ differs from ‘MP003’ in having flowers that are pale purple in color. The male parent of ‘MP003’ differs from ‘MP003’ in having lower inflorescence production and a taller plant height. ‘MP003’ can be most closely compared to the Agapanthus cultivars ‘Purple Delight’ (not patented) and ‘Amethyst’ (not patented). ‘Purple Delight’ and ‘Amethyst’ are similar to ‘MP003’ in having flowers that are purple in color. ‘Purple Delight’ differs from ‘MP003’ in having a slower growing habit, pale purple flower color and less inflorescence production and re-blooming. ‘Amethyst’ differs from ‘MP003’ in having flowers that are pale purple in color, a smaller plant size and less re-blooming.

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 plants about 2 years in age (from a bare root division) of ‘MDB001’ as grown outdoors in a 3-gallon container in Hartebeespoort, Northwest Province, South Africa.

The photograph in FIG. 1 provides a side view of a plant of ‘MP003’ in bloom.

The photograph in FIG. 2 provides a close-up view of an inflorescence of ‘MP003’.

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 following is a detailed description of 1 year-old plants (from a bare root division) of ‘MP003’ as grown outdoors in 3-gallon containers in Loxley, Ala. 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 2015 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
