Abstract

A new cultivar of Miscanthus, Miscanthus sinensis ‘Gold Bar’, that is characterized by its densely banded creamy yellow and green foliage, its short stature, its dense and upright plant habit, and its late season bloom.

Description

BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Miscanthus sinensis and will be referred to hereafter by its cultivar name, ‘Gold Bar’. ‘Gold Bar’ represents a new cultivar of Japanese silver grass, a cold hardy, perennial ornamental grass grown for landscape use.
The inventors discovered and selected the new cultivar, ‘Gold Bar’, in a cultivated area at their nursery in Scappoose, Oreg. ‘Gold Bar’ was discovered as a seedling produced by open-pollination of Miscanthus sinensis ‘Strictus’ (un-patented) and selected after evaluation in a test bed for a period of seven years.
The new cultivar ‘Gold Bar’ was selected for the unique banding pattern of its leaf blades combined with its dense, bushy and upright growth habit and its shorter height in comparison to ‘Strictus’ and other cultivars of Miscanthus known to the inventors.
Asexual reproduction of the new cultivar was first accomplished by culm division in Scappoose, Oreg. in late winter of 2000 by the inventors. The characteristics of this cultivar have been determined to be 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. The new Miscanthus 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 measurements, observations, and descriptions that follow describe plants that were grown outdoors in Scappoose, Oreg. and observed for a period of seven years. These attributes in combination distinguish ‘Gold Bar’ from ‘Strictus’ and any other selections of Miscanthus known to the inventors.
1. The foliage of ‘Gold Bar’ exhibits a banding pattern of 12 to 17 creamy yellow bands while the banding pattern of ‘Strictus’ consists of 2 to 3 creamy yellow bands per leaf blade of about 10 inches in length.
2. ‘Gold Bar’ is short in stature; reaching a height of about 4 to 5 feet while ‘Strictus’ reaches a height of about 7 to 8 feet.
3. The growth habit of ‘Gold Bar’ is upright with rigid culms and foliage that is more dense and bushy in comparison to ‘Strictus’.
4. ‘Gold Bar’ blooms in mid to late October in the Northwest and may not bloom in northern climates due to early frosts. ‘Strictus’ blooms in September.
5. ‘Gold Bar’ has more densely banded foliage, is more upright in habit, and has stiffer leaf blades than the Miscanthus cultivars ‘Kirk Alexander’ (un-patented) ‘Puenktchen’ (un-patented), and Miscanthus ‘Little Zebra’ (U.S. Plant Pat. No. 13,008), three cultivars known to the inventors to have banded foliage and short stature.
BRIEF DESCRIPTION OF THE DRAWING
The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Miscanthus.
The photograph on the top of the sheet illustrates the overall habit and appearance of ‘Gold Bar’ in October in Scappoose, Oreg. as grown outdoors for seven years.
The photograph on the bottom of the sheet is of a plant as grown outdoors in a one-gallon container and is a close-up view of the banding pattern characteristic of the foliage of ‘Gold Bar’. 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 Miscanthus.
DETAILED BOTANICAL DESCRIPTION
The following is a detailed description of the new cultivar as grown in an outdoor trial bed for seven years in Scappoose, Oreg. 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.
Botanical classification: ‘Gold Bar’ is a cultivar of Miscanthus sinensis.
Common Name: ‘Gold Bar’ Japanese silver grass or ‘Gold Bar’ Porcupine grass.
Parentage: Naturally occurring seedling by open-pollination of Miscanthus sinensis ‘Strictus’.
General description:
Blooming period.—Blooms in mid to late October in the Northwest U.S. or not at all in shorter growing seasons or when early frosts occur. Blooms are retained over the winter if present.
Plant habit.—Herbaceous, clump-forming, ornamental grass with an upright, rigid form and dense, bushy foliage.
Height and spread.—Reaches up to 5 feet in height with a spread of about 18 inches (at base) in 4 years of growing time.
Hardiness.—Zone 4 to 9.
Culture.—Grows best in fertile, moist soil in full sun. Tolerates wet soils and light shade in climates with high temperatures.
Diseases and pests.—No susceptibility or resistance to diseases or pests that affect Miscanthus has been observed.
Root description.—Fibrous.
Growth and propagation:
Propagation.—Culm division, best divided in spring when in active growth.
Time required for root development from a single division.—A two to three culm division planted in a bark-based media will fully develop roots in a 6 inch deep 4 inch square container in 2 to 3 months when grown outdoors under standard summer temperatures and natural lighting in the Northwest U.S.
Growth rate.—Slow to moderate.
Culm (stem) description:
General.—Cylindrical, flattened, completely enclosed by leaf sheaths in a fan-like arrangement.
Culm aspect.—Rigid and held erect, none are cascading.
Culm color.—146B.
Culm size.—About ½ to ¾ inch wide, up to 4 to 5 feet in height on mature plants.
Culm surface.—Glabrous with very fine white hairs.
Internode length.—Varies from about 7 to 8 inches from the base of the culm to the first ligule and to about 1 to 3 inches for the more distal internodes. Internode length decreases gradually from the base to the apex of the culm.
Ligule.—Membranous, about ⅛ to {fraction (1/16)}″ inches in width and 161B in color with very fine white hairs, encircles the entire culm.
Foliage description:
Leaf shape.—Linear.
Leaf division.—Simple.
Leaf base.—Sheathed.
Leaf apex.—Acute.
Leaf aspect.—Emerging leaves are erect, leaf blades diverge from leaf sheath at ligule at up to a 30° angle from center of culm. Blades are concave in respect to the culm.
Leaf venation.—Parallel, mid rib is raised on upper surface but not conspicuous, color matches the color of the leaf blades.
