plant named ‘Glow Sticks’

Abstract

A new cultivar of Festuca plant named ‘Glow Sticks’ that is characterized by its light yellow flower stalks and inflorescences that rise above a dark green tuft of foliage and its foliage that is dark green in color with a subtle central stripe that is white in color.

Description

Botanical classification: Festuca arundinacea.

Varietal denomination: ‘Glow Sticks’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Festuca arundinacea and will be referred to hereafter by its cultivar name, ‘Glow Sticks’. ‘Glow Sticks’ is a new cultivar of perennial ornamental grass grown for container and landscape use.

The new cultivar, ‘Glow Sticks’ was discovered by the Inventor as a chance seedling in May 2014 that was growing in a garden in Wake Co, N.C. The exact parentage is unknown; however, it is most likely a seedling of an unnamed plant of Festuca arundinacea based on its characteristics and its proximity to the new cultivar. The new cultivar underwent several division selections until a stable central stripe on the leaf was obtained in October 2016.

Asexual propagation of the new cultivar was first accomplished by division by the Inventor in Raleigh, N.C. in 2017. Asexual propagation by division has shown 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 ‘Glow Sticks’ as a unique cultivar of Festuca.

• • 1. ‘Glow Sticks’ exhibits light yellow flower stalks and inflorescences that rise above a dark green tuft of foliage.
  • 2. ‘Glow Sticks’ exhibits foliage that is dark green in color with a subtle central stripe that is white in color.

Typical plants of Festuca arundinacea differs from ‘Glow Sticks’ in having foliage that is all green in color and flower stalks and inflorescences that are all green in color. Although a few agronomic varieties have been named based on adapting to certain agronomic growing conditions, there are no known cultivars of Festuca arundinacea with unique ornamental characteristics known to the Inventor. ‘Glow Sticks’ can be compared to Bromus inermis cultivar ‘Skinner's Gold’ (not patented). ‘Skinner's Gold’ is similar to ‘Glow Sticks’ in having yellow inflorescences and leaves with a white central stripe. In addition to being a different genus, ‘Skinner's Gold’ differs from ‘Glow Sticks’ in having leaves with a much wider white central stipe.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying color photograph illustrates the overall appearance and distinct characteristics of the new Festuca. The photograph was taken of a group of 24-month-old plants (from 4-inch wide divisions) of ‘Glow Sticks’ as grown outdoors in a garden in Raleigh, N.C. The photograph illustrates the overall plant habit and appearance of ‘Glow Sticks’ in bloom. The colors in the photograph 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 Festuca.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of 6-month-old plants (from a 6-inch wide division) of ‘ Glow Sticks’ as grown outdoors in one-gallon containers in Raleigh, N.C. 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 2015 Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
