USPP28491P2 - Molinia plant named ‘Dark Beauty’ - Google Patents

Abstract

A new cultivar of Molinia, ‘Dark Beauty’, that is characterized by its tall plant height of 220 cm and its flower dark colored spikes that are fine in texture.

Description

Botanical classification: Molinia litoralis.

Varietal denomination: ‘Dark Beauty’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Molinia litoralis and will be referred to hereafter by its cultivar name, ‘Dark Beauty’. ‘Dark Beauty’ represents a new cultivar of herbaceous perennial, an ornamental grass grown for landscape use.

The Inventor discovered the new cultivar, ‘Dark Beauty’, as a chance seedling in the Inventors garden in Hummelo, Netherlands in the summer of 2009. Although the parentage is unknown, Molinia litoralis ‘Transparent’ (not patented) is thought to be a likely parent based on the characteristics of ‘Dark Beauty’ and its proximity in the same growing area.

Asexual propagation of the new cultivar was first accomplished by division in Hummelo, Netherlands in 2010 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 ‘Dark Beauty’ as a unique cultivar of Molinia.

• • 1. ‘Dark Beauty’ exhibits a plant height of 220 cm.
  • 2. ‘Dark Beauty’ exhibits flower spikes that are fine in texture.
  • 3. ‘Dark Beauty’ exhibits dark colored flower spikes (due to stigmas).

‘Dark Beauty’ can be most closely compared to cultivars, Molinia litoralis ‘Transparent’ and Molinia litoralis ‘Skyracer’ (not patented). ‘Transparent’ differs from ‘Dark Beauty’ in having flower spikes that are lighter in color and a more open plant habit. ‘Skyracer’ differs from ‘Dark Beauty’ in having a taller plant height, in having a more upright growth habit and in lacking dark colored flower spikes.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photograph illustrates the characteristics of 3 year-old plant of ‘Dark Beauty’ as grown in a garden in Hummelo, Netherlands. The photograph provides a side view of ‘Dark Beauty’. The colors in the photographs are as close as possible with the digital photography techniques available, the color values cited in the detailed botanical description accurately describe the colors of the new Molinia.

DETAILED BOTANICAL DESCRIPTION
