plant named ‘MDB001’

Abstract

A new cultivar of Agapanthus, ‘MDB001’, that is characterized by its white and blue bi-color flowers that are pendulous, its flower umbels that are large in size, and its compact plant habit with short and broad leaves.

Description

Botanical classification: Agapanthus hybrid.

Varietal denomination: ‘MDB001’.

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, ‘MDB001’. ‘MDB001’ 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 of medium stature with neat foliage and bi-color flowers. 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 ‘MDB001’ in November of 2010 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 2012. 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 ‘MDB001’ as a distinct cultivar of Agapanthus.

• • 1. ‘MDB001’ exhibits white and blue bi-color flowers that are pendulous.
  • 2. ‘MDB001’ exhibits flower umbels that are large in size.
  • 3. ‘MDB001’ exhibits a compact plant habit with short and broad leaves.

The female parent of ‘MDB001’ differs from ‘MDB001’ in having flowers that are held upright and leaves that are longer and strappy in appearance. The male parent of ‘MDB001’ differs from ‘MDB001’ in having flowers that are solid pale blue in color. ‘MDB001’ can be most closely compared to the Agapanthus cultivars ‘AMBIC001’ (U.S. Plant Pat. No. 25,519) and ‘PMN06’ (U.S. Plant Pat. No. 24,651). ‘AMBIC001’ and ‘PMN06’ are both similar to ‘MDB001’ in having bi-color flowers. ‘AMBIC001’ differs from ‘MDB001’ in having longer and thinner leaves and umbels that are smaller in size with shorter pedicels. ‘PMN06’ differs from ‘MDB001’ in having a larger plant size and lower inflorescence production.

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 ‘MDB001’ in bloom.

The photograph in FIG. 2 provides a close-up view of the inflorescences of ‘MDB001’.

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 ‘MDB001’ 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.
