Description

Latin name of the genus and species of the plant claimed: Schizachyrium scoparium.

Variety denomination: The new Schizachyrium scoparium claimed is of the cultivar denominated ‘Good Vibrations’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Schizachyrium scoparium hereinafter referred to by the varietal domination ‘Good Vibrations’.

The new Schizachyrium is a product of a planned breeding program conducted by the Inventors in Griffin, Ga. The objective of the Schizachyrium breeding program is to produce a tough and adaptable drought-tolerant plant with commercial value. This cultivar has significant commercial and home gardener appeal with its attractive foliage and low maintenance requirements. These and other qualities are enumerated herein.

Pedigree and history: In 2006, thirty-seven accessions (number of plants per accession ranged from one to 51 depending upon the germination of individual accessions) of Schizachyrium scoparium were germinated and transplanted into field plots in Griffin, Ga. After a two-year evaluation period, seeds from open pollination within accessions were collected and sown in 2008, yielding 368 seedlings. The 368 seedlings were evaluated in containers in a screenhouse in Griffin, Ga. A seedling from plant B19, was selected for further evaluation and labeled ‘B19-23’. Seeds from open pollination were collected from ‘B19-23’ and were sown in spring 2009. The resulting seedlings were evaluated in containers in the screenhouse for two seasons. The new variety ‘B19-23-78’, now called ‘Good Vibrations’, was selected and was first asexually propagated in 2010 in Griffin, Ga. by root division, and planted into a field plot. The new variety ‘Good Vibrations’ has been tested since 2011 in Griffin and Blairsville, Ga.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of a new variety Schizachyrium scoparium, ‘Good Vibrations’. The new variety ‘Good Vibrations’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in, for example, temperature, day-length, light intensity, soil types, and water and fertility levels without, however, any variance in genotype.

Asexual reproduction of the new Schizachyrium ‘Good Vibrations’ by root division since 2010 has shown that the unique features of this new Schizachyrium are stable and reproduced true to type in successive generations.

‘Good Vibrations’ plants, along with the cultivars ‘MinnblueA’ (U.S. Plant Pat. No. 17,310) and ‘Carousel’ (U.S. Plant Pat. No. 20,948) have been evaluated since 2011 in field plots at Griffin, Ga. and Blairsville, Ga. Height from the soil to the tip of the flowering culm, height from the soil to the top of the foliage and width were collected each year from the Griffin plants. Foliage color was assessed monthly from May to September each year.

Throughout this specification, color names beginning with a small letter signify that the name of that color, as used in common speech, is aptly descriptive. Color names beginning with a capital letter designate values based upon The R.H.S. Colour Chart, 5^th edition published by The Royal Horticultural Society, London, England.

The following traits have been consistently observed in the original plant of this new variety and in asexually propagated progeny grown from root divisions in Blairsville, and Griffin, Ga., and, to the best knowledge of the inventors, their combination forms the unique characteristics of the new variety ‘Good Vibrations’:

• • 1. Foliage of ‘Good Vibrations’ is purple and green from May to September.
  • 2. ‘Good Vibrations’ exhibits an upright to softly arching growth habit.

The new variety Schizachyrium ‘Good Vibrations’ can be compared to the cultivars ‘Carousel’ and ‘MinnblueA’. Plants of the new Schizachyrium differ from ‘Carousel’ and ‘MinnblueA’ in the following characteristics:

• • 1. The new variety ‘Good Vibrations’ exhibits similar total height to ‘MinnblueA’ and a greater total height than ‘Carousel’.
  • 2. The new variety ‘Good Vibrations’ has greater average foliage height than ‘Carousel’ and ‘MinnblueA’.
  • 3. The average canopy diameter of the new variety ‘Good Vibrations’ is narrower than the canopy diameter of ‘MinnblueA’.
  • 4. The new variety ‘Good Vibrations’ is different from ‘Carousel’ and ‘MinnblueA’ in foliage growth. The new variety ‘Good Vibrations’ has upright foliage transitioning to cascading foliage throughout the growing season, whereas ‘Carousel’ and ‘MinnblueA’ have mostly upright pointing foliage.
  • 5. The new variety ‘Good Vibrations’ is different from ‘Carousel’ and ‘MinnblueA’ in foliage color. The foliage of the new variety ‘Good Vibrations’ is purple and green throughout the growing season, while the foliage of ‘Carousel’ and ‘MinnblueA’ is mostly green to green-blue.

The following observations, measurements, and values describe plants grown in Griffin, Ga. ‘Good Vibrations’ was propagated via root division and grown in one-quart containers prior to planting in field plots. All data are from plants established as single stem propagules in May 2011.

The new variety ‘Good Vibrations’ has colorful purple and green to yellow-green upright to cascading foliage throughout the summer, in contrast to the green to blue-green foliage of ‘Carousel’ and ‘MinnblueA’ (Table 1). ‘Good Vibrations’ was on average similar in height to ‘MinnblueA’. ‘Good Vibrations’ displayed greater foliage height than ‘Carousel’ at test sites in Griffin, Ga. (Table 2). ‘MinnblueA’ exhibited the greatest foliage width of these three cultivars (Table 2). The new variety ‘Good Vibrations’ is observed to have a lower plant width to foliage height ratio than ‘MinnblueA’, ‘Carousel’, ‘Blaze’ (unpatented), ‘The Blues’ (unpatented) and ‘Prairie Blues’ (unpatented) and a lower plant width to total height ratio than ‘Carousel’, ‘MinnblueA’, and ‘Blaze’ (Table 3).

At the same age of development and under the same growing conditions ‘Good Vibrations’ is shorter in total height than ‘Seasons in the Sun’ (patent pending) and ‘Cinnamon Girl’ (patent pending).

‘Seasons in the Sun’ and ‘Cinnamon Girl’ have an upright rounded growth habit with cascading foliage from May to September, but the foliage of ‘Good Vibrations’ is upright in early summer, changing to cascading in midsummer.

Foliage colors vary during the growing season among these three cultivars. ‘Good Vibrations’ in early summer has Violet-Blue N92D, ‘Seasons in the Sun’ has Purple N77A or Purple 79A and ‘Cinnamon Girl’ has Purple N79C or Greyed-Purple 187A on the distal portion of the foliage. In mid-summer, while all three cultivars have various shades of Greyed-Purple on the distal portion of the leaves, ‘Good Vibrations’ also has Purple N77C. In late summer, both ‘Cinnamon Girl’ and ‘Good Vibrations’ have some Yellow-Green 144A leaves, while ‘Seasons in the Sun’ has some Green 138B leaves. Furthermore, ‘Cinnamon Girl’ has some Red-Purple 59A or Red-Purple 60C foliage, colors not seen in the other cultivars.

‘Blaze’	1.20	0.58	0.49
‘The Blues’	1.50	0.44	0.30
‘Prairie Blues’	1.53	0.43	0.28

In Table 3, the relationship between foliage height and plant width is presented.

In summary, ‘Good Vibrations’ has more varied foliage color than ‘Carousel’ and ‘MinnblueA’ but is taller in total height than ‘Carousel’ and a little shorter in total height than ‘MinnblueA’. ‘Good Vibrations’ and ‘Carousel’ are narrower than ‘MinnblueA’ in foliage width. ‘Good Vibrations’ is upright and rounded, with foliage height being close to width, in early summer while both ‘Carousel’ and ‘MinnblueA’ are broadly rounded, displaying width greater than foliage height. By late summer, ‘Good Vibrations’ displays cascading foliage with foliage width being less than half of the total height; while width of ‘MinnblueA’ and ‘Carousel’ is over half of their total height.

BOTANICAL DESCRIPTION

The new variety ‘Good Vibrations’ is a perennial at Griffin, Ga. (USDA Zone 8a). The new variety ‘Good Vibrations’ blooms from mid-July to early August. ‘Good Vibrations’ is drought tolerant and is expected to be able to be grown in USDA Zones 3-9. ‘Good Vibrations’ grows well in full sun and in most soils. The foliage is fine-textured and long-lived. It appears to be genetically stable and has been asexually propagated by root division.
