Abstract

A new and distinct cultivar of Agapanthus plant named ‘Moonlight Star’, characterized by its upright and relatively compact plant habit; outwardly arching leaves; numerous star-shaped flowers with light and dark violet blue-striped flowers arranged on upright and strong scapes; and good garden performance.

Description

Botanical designation: Agapanthus africanus.

Cultivar denomination: ‘MOONLIGHT STAR’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Agapanthus plant, botanically known as Agapanthus africanus and hereinafter referred to by the name ‘Moonlight Star’.

The new Agapanthus plant is the result of a cross-pollination made by the Inventors in June, 1999 of two unnamed proprietary seedling selections of Agapanthus africanus, not patented. The new Agapanthus plant was discovered and selected by the Inventors as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled environment in Roelofarendsveen, The Netherlands in June, 2002.

Asexual reproduction of the new Agapanthus plant by divisions in a controlled environment in Roelofarendsveen, The Netherlands since February, 2003 has shown that the unique features of this new Agapanthus plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Agapanthus have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Moonlight Star’. These characteristics in combination distinguish ‘Moonlight Star’ as a new and distinct Agapanthus plant:

- 1. Upright and relatively compact plant habit.
- 2. Outwardly arching leaves.
- 3. Numerous star-shaped flowers with light and dark violet blue-striped flowers arranged on upright and strong scapes.
- 4. Good garden performance.

Plants of the new Agapanthus differ primarily from plants of the female parent selection in the following characteristics:

- 1. Plants of the new Agapanthus are more compact than plants of the female parent selection.
- 2. Plants of the new Agapanthus and the female parent selection differ in flower color.

Plants of the new Agapanthus differ primarily from plants of the male parent selection in the following characteristics:

- 1. Plants of the new Agapanthus are more compact than plants of the male parent selection.
- 2. Plants of the new Agapanthus and the male parent selection differ in flower color.

Plants of the new Agapanthus can be compared to plants of ‘Blue Heaven’, disclosed in U.S. Plant Pat. No. 14,989. In side-by-side comparisons conducted in Boskoop, The Netherlands, plants of the new Agapanthus and ‘Blue Heaven’ differed in the following characteristics:

- 1. Plants of the new Agapanthus were more compact than plants of ‘Blue Heaven’.
- 2. Plants of the new Agapanthus and ‘Blue Heaven’ differed in flower color as plants of ‘Blue Heaven’ had violet blue-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Agapanthus plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Agapanthus plant.

The photograph on the first sheet comprises a top perspective view of a typical flowering plant of ‘Moonlight Star’ grown in a container.

The photograph at the top of the second sheet is a close-up view of a typical inflorescence of ‘Moonlight Star’.

The photograph at the bottom of the second sheet is a close-up view of typical leaves of ‘Moonlight Star’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the late spring and early summer in 17-cm containers in a greenhouse in Boskoop, The Netherlands and under cultural practices typical of commercial Agapanthus production. During the production of the plants, day temperatures ranged from 15° C. to 23° C. and night temperatures ranged from 8° C. to 16° C. Plants were two years old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
