Abstract
A new cultivar of Pennisetum setaceum named ‘Fireworks’, characterized by its unique variegated foliage comprised of vertical bands of burgundy, green, and white combined with a vigorous growth habit and showy pale red-purple plumes from early summer until frost.
Description
Botanical classification: Pennisetum setaceum.
Varietal denomination: ‘Fireworks’.
The present invention relates to a new and distinct cultivar of Pennisetum setaceum and will be referred to hereafter by its cultivar name, ‘Fireworks’. ‘Fireworks’ represents a new cultivar of Purple fountain grass, a warm-season, ornamental grass grown for container and landscape use.
The inventor discovered and selected the new cultivar, ‘Fireworks’, as a culm sport of Pennisetum setaceum ‘Rubrum’ (not patented) in a container at his nursery in Leola, Pa. in spring of 2004.
The new cultivar ‘Fireworks’ was selected for the unique foliage coloration with leaf blades that are variegated with longitudinal stripes of white, green and burgundy that impart a candy cane-like appearance. The parent plant, Pennisetum setaceum ‘Rubrum’, has foliage that is non-variegated; burgundy in color when grown in full sun and green in color when grown in full shade. ‘Fireworks’ can also be compared to Pennisetum setaceum ‘Cupreum’ (not patented), which has green to red foliage and lacks leaf variegation.
Asexual reproduction of the new cultivar was first accomplished by culm division in Leola, Pa. in June of 2004 by the inventor. The characteristics of this cultivar have been determined to be stable and are reproduced true to type in successive generations via division and tissue culture.
The following traits have been repeatedly observed and represent the characteristics of the new cultivar. The new Pennisetum has not been observed under all possible environmental conditions. 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 general observations, and descriptions that follow describe plants that were grown outdoors in Leola, Pa. for a period of one year. These attributes in combination distinguish ‘Fireworks’ from all other selections of Pennisetum known to the inventor.
-
- 1. The foliage of ‘Fireworks’ exhibits a longitudinal banding pattern of vertical bands of white, burgundy, and green. The parent plant has foliage that is non-variegated with foliage that is solid burgundy or green foliage dependent on light levels.
- 2. ‘Fireworks’ reaches a height of about 1.2 m (4 ft), and a spread of about 0.8 m, similar to the parent plant.
- 3. ‘Fireworks’ blooms in late June until frost in Pennsylvania with plumes that open red-purple color and turn light brown as they mature.
- 4. ‘Fireworks’ exhibits a vigorous growth habit.
- 5. ‘Fireworks’ is a grown as a tender perennial in climates colder than USDA Zone 9.
The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Pennisetum as grown for one year.
The photograph in FIG. 1 was taken in late summer and illustrates the overall habit and appearance of ‘Fireworks’ as grown outdoors in a trial plot in Leola, Pa.
The photograph on FIG. 2 is a close-up view of the foliage coloration of ‘Fireworks’.
The colors in the photographs are as close as possible with the photographic and printing technology utilized. The color values cited in the detailed botanical description accurately describe the colors of the new Pennisetum.
The general observations and descriptions describe plants that are one year in age as grown outdoors in a two-gallon container. The color determinations are in accordance with the 2001 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
