ABSTRACT:

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.
