plant named ‘EXC 052’

Abstract

A new and distinct cultivar of Liriope plant named ‘EXC 052’, characterized by its compact and outwardly arching plant habit with long and upright inflorescence stalks; freely flowering habit; large violet-colored flowers; and good garden performance.

Description

Botanical designation: Liriope muscari.

Cultivar denomination: ‘EXC 052’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Liriope plant, botanically known as Liriope muscari and hereinafter referred to by the name ‘EXC 052’.

The new Liriope plant is a naturally-occurring whole plant mutation of Liriope muscari ‘Moneymaker’, not patented. The new Liriope was discovered and selected by the Inventor as a flowering plant from within a population of plants of the parent in a controlled outdoor nursery environment in Boijl, The Netherlands in June, 2005.

Asexual reproduction of the new Liriope plant by divisions in a controlled environment in Boijl, The Netherlands since the spring of 2006, has shown that the unique features of this new Liriope plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Liriope have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices 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 ‘EXC 052’. These characteristics in combination distinguish ‘EXC 052’ as a new and distinct cultivar of Liriope:

• • 1. Compact and outwardly arching plant habit with long and upright inflorescence stalks.
  • 2. Freely flowering habit.
  • 3. Large violet-colored flowers.
  • 4. Good garden performance.

Plants of the new Liriope differ from plants of the parent, ‘Moneymaker’, in the following characteristics:

• • 1. Plants of the new Liriope are larger than plants of ‘Moneymaker’.
  • 2. Plants of the new Liriope have longer inflorescences than plants of ‘Moneymaker’.
  • 3. Inflorescences of plants of the new Liriope have more flowers than inflorescences of ‘Moneymaker’.
  • 4. Plants of the new Liriope have darker colored flowers than plants of ‘Moneymaker’.
  • 5. Plants of the new Liriope are tolerant to lower temperatures than plants of ‘Moneymaker’.

Compared to plants of Liriope muscari ‘Love Potion No. 13’, disclosed in U.S. Plant Pat. No. 15,471, plants of the new Liriope are more compact, have narrower leaves and are more freely flowering than plants of ‘Love Potion No. 13’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Liriope, 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 Liriope.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘EXC 052’.

The photograph on the second sheet is a close-up view of typical inflorescences of ‘EXC 052’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in Boijl, The Netherlands, under commercial practice during the summer and autumn in an outdoor nursery. Plants were four months old when the photographs and description were taken.
