Abstract

A new cultivar of Koeleria glauca, ‘Cornish Blue’, that is characterized by its foliage that is variegated with thin green centers and wide creamy white margins.

Description

Botanical classification: Koeleria glauca.
Varietal denomination: ‘Cornish Blue’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Koeleria glauca and will be referred to hereafter by its cultivar name, ‘Cornish Blue’. ‘Cornish Blue’ is a new cultivar of perennial ornamental grass grown for container and landscape use.
The new cultivar was bred and selected by the Inventor in West Sussex, United Kingdom. The Inventor made a cross in September of 2006 between unnamed plants of Koeleria glauca as both the female and male parents. The Inventor selected ‘Cornish Blue’ as a single unique plant amongst the seedlings that resulted from the above cross.
Asexual propagation of the new cultivar was first accomplished by division in West Sussex, United Kingdom in October of 2008 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 ‘Cornish Blue’ as a unique cultivar of Koeleria.
    • 1. ‘Cornish Blue’ exhibits foliage that is variegated with thin green centers and wide creamy white margins.
The parent plants, unnamed plants of Koeleria glauca, differ from ‘Cornish Blue’ in having non-variegated foliage that is green in color. There are no other cultivars of Koeleria glauca with variegated foliage that are known to the Inventor. The only cutivar of Koeleria glauca known to the Inventor is ‘Blue Sprite’, a non-patented seed strain with a dwarf plant habit and blue-green foliage.
BRIEF DESCRIPTION OF THE DRAWING
The accompanying colored photographs illustrate the overall appearance and distinct characteristics of a one year-old plant of the new cultivar as grown outdoors in a 9-cm container in West Sussex, United Kingdom.
The photograph in FIG. 1 illustrates the overall plant habit and appearance of ‘Cornish Blue’.
The photograph in FIG. 2 provides a close-up view of the foliage of ‘Cornish Blue’. The colors in the photograph may differ slightly from the color, values cited in the detailed botanical description, which accurately describe the colors of the new Koeleria.
DETAILED BOTANICAL DESCRIPTION
The following is a detailed description of one year-old plants of the new cultivar as grown outdoors in a 9-cm containers in West Sussex, United Kingdom. The phenotype may vary somewhat with variations in temperature, day-length, light intensity, soil types, and water and fertility levels without, however, any variance in genotype. The color determinations are in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
