USPP28519P2 - Molinia plant named ‘Crystal Veil’ - Google Patents

Abstract

A new cultivar of Molinia, ‘Crystal Veil’, that is characterized by its tall plant height of 200 cm and flower spikes that are fine in texture.

Description

Botanical classification: Molinia litoralis.

Varietal denomination: ‘Crystal Veil’.

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, ‘Crystal Veil’. ‘Crystal Veil’ represents a new cultivar of herbaceous perennial, an ornamental grass grown for landscape use.

The Inventor discovered the new cultivar, ‘Crystal Veil’, as a chance seedling in the Inventors garden in Hummelo, Netherlands in the summer of 2010. Although the parentage is unknown, Molinia litoralis ‘Transparent’ (not patented) is thought to be a likely parent based on the characteristics of ‘Crystal Veil’ and its proximity in the same growing area.

Asexual propagation of the new cultivar was first accomplished by division in Hummelo, Netherlands in 2012 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 ‘Crystal Veil’ as a unique cultivar of Molinia.

• • 1. ‘Crystal Veil’ exhibits a plant height of 200 cm.
  • 2. ‘Crystal Veil’ exhibits flower spikes that are fine in texture (finer than is typical of plants of Molinia litoralis.

‘Crystal Veil’ can be most closely compared to cultivars, Molinia litoralis ‘Transparent’ (not patented) and Molinia litoralis ‘Skyracer’ (not patented). ‘Transparent’ differs from ‘Crystal Veil’ in having flower spikes that are larger in size and finer in texture and in having a taller and more arching plant habit. ‘Skyracer’ differs from ‘Crystal Veil’ in having a taller plant height and in having a more upright plant habit.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photograph were taken in October and illustrate the characteristics of 4 year-old plants as grown in a garden in Hummelo, Netherlands. The photograph 1 provides a side view of ‘Crystal Veil’. 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.
