plant named ‘Nongmn’

Abstract

A new cultivar of Liriope minor called ‘Nongmn’, that is characterized by its foliage that reaches a height of only 10 cm, its flower stems that reach a height of only 7 cm and its dense, low growing plant habit that forms a turf-like thicket.

Description

Botanical classification: Lirope minor.

Variety denomination: ‘Nongmn’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Liriope minor named ‘Nongmn’ and will be referred to hereafter by its cultivar name, ‘Nongmn’. The new cultivar represents a new herbaceous perennial grown for landscape use.

The new cultivar was developed by the Inventor at his nursery in Nunica, Mich. Approximately 10,000 seeds, resulting from the open pollination of a proprietary unnamed Liriope minor plant (not patented) in the Inventor's breeding program, were sown. ‘Nongmn’ was selected in June 2004 from amongst the resulting seedlings

Asexual propagation of the new cultivar was first accomplished by division in Nunica, Mich. in June of 2005 by the Inventor. 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. These attributes in combination distinguish ‘Nongmn’ as a unique cultivar of Liriope.

• • 1. ‘Nongmn’ exhibits foliage that reaches a height of only 10 cm.
  • 2. ‘Nongmn’ exhibits flower stems that reach a height of only 7 cm.
  • 3. ‘Nongmn’ exhibits a dense, low growing plant habit that forms a turf-like thicket.
    Typical plants of Liriope minor, the parent species of ‘Nongmn’, differ from ‘Nongmn’ in having foliage that reaches 20 cm in height and flower stems that reach 10 cm in length. All other attributes are similar. ‘Nongmn’ can be compared to Liriope minor cultivar ‘Torafu’ (not patented). ‘Torafu’ is similar to ‘Nongmn’ in foliage height, but differs from ‘Nongmn’ in having foliage with irregular creamy yellow horizontal bands and in having a less dense growth habit. There are no other cultivars of Liriope minor known to the Inventor.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Liriope. The photographs were taken of 1-year-old plants as grown in the ground in Nunica, Mich.

The photograph in FIG. 1 provides a view of a mass planting of ‘Nongmn’ in bloom.

The photograph in FIG. 2 provides a view of an inflorescence of ‘Nongmn’.

The photograph in FIG. 3 provides a view of the foliage height of ‘Nongmn’.

The 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.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of three year-old plants of the new cultivar as grown outdoors in the Inventor's nursery in Nunica, Mich. 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 determination is in accordance with The 1988 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
