USPP30802P2 - Miscanthus plant named ‘EMPMIS01’ - Google Patents

Abstract

A new cultivar of Miscanthus, Miscanthus sinensis ‘EMPMIS01’, that is characterized by its flower plumes that are dark red in color, its compact plant habit and short plant height, its long flowering period, and its floriferous blooming habit in producing numerous flowering stems.

Description

Botanical classification: Miscanthus sinensis.

Cultivar designation: ‘EMPMIS01’.

CROSS REFERENCE TO A RELATED APPLICATION

This application is related to a European plant breeders' rights application filed on Apr. 20, 2015, application No. 2015/0874. There have been no offers for sale anywhere in the world prior to the effective filing date of this Application and no accessibility to one of ordinary skill in the art could have been derived from the printed plant breeder's rights documents.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Miscanthus sinensis and will be referred to hereafter by its cultivar name, ‘EMPMIS01’. ‘EMPMIS01’ represents a new cultivar of Japanese silver grass, a cold hardy, perennial ornamental grass grown for landscape use.

‘EMPMIS01’ was discovered by the Inventors as a chance seedling in a trial field in Berltsum, The Netherlands in August of 2010. The parentage is unknown.

Asexual propagation of the new cultivar was first accomplished by division by one of the Inventors in Harich, The Netherlands in January 2015. 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 are determined to be the characteristics of the new cultivar. These attributes in combination distinguish ‘EMPMIS01’ as a unique cultivar of Miscanthus.

• 1. ‘EMPMIS01’ exhibits flower plumes that are dark red in color.
• 2. ‘EMPMIS01’ exhibits a compact plant habit and short plant height.
• 3. ‘EMPMIS01’ exhibits a long flowering period.
• 4. ‘EMPMIS01’ exhibits a floriferous blooming habit in producing numerous flowering stems.

‘EMPMIS01’ can be most closely compared to the cultivar ‘Kleine Fontaine’ (not patented) and ‘Gracillimus’ (not patented). ‘Kleine Fontaine’ is similar to ‘EMPMIS01’ in having weeping inflorescences. ‘Kleine Fontaine’ differs from ‘EMPMIS01’ in having a taller plant height, flowers that are light red in color, and a shorter blooming period. ‘Gracillimus’ is similar to ‘EMPMIS01’ in having coppery red flowers when opening and thin foliage with a white midrib. ‘Gracillimus’ differs from ‘EMPMIS01’ in having a taller plant height and in blooming later in the season.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Miscanthus. The photographs were taken in September of plants 4 years in age as grown outdoors in a 40-cm container in Berltsum, The Netherlands.

The photograph in FIG. 1. provides a side view of a plant of ‘EMPMIS01’ and illustrates the overall plant habit and general appearance in bloom.

The photograph in FIG. 2. provides a close-up view of the inflorescences of ‘EMPMIS01.

The photograph in FIG. 3. provides a close-up view of a leaf of ‘EMPMIS01’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the Detailed Botanical Description accurately describe the colors of the new Miscanthus.
