Miscanthus plant named ‘Super Stripe’

Abstract

A new and distinct cultivar of miscanthus plant named ‘Super Stripe’, characterized by its relatively compact, upright to somewhat outwardly spreading plant habit; dense and bushy growth habit; vigorous growth habit; green-colored leaves with yellow green-colored bands; and good garden performance.

Description

Botanical designation: Miscanthus sinensis.

Cultivar denomination: ‘Super Stripe’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Miscanthus plant, botanically known as Miscanthus sinensis, and hereinafter referred to by the name ‘Super Stripe’.

The new Miscanthus is a product of a planned breeding program conducted by the Inventor in Avondale, Pa. The objective of the program is to create and develop new Miscanthus cultivars having good plant habit and unique leaf banding patterns.

The new Miscanthus originated from an open-pollination of the Miscanthus sinensis cultivar Zebrinus, not patented, as the female, or seed, parent with an unknown selection of Miscanthus sinensis as the male, or pollen, parent. The new Miscanthus was discovered and selected by the Inventor as a single plant within the progeny of the stated open-pollination in a controlled environment in Avondale, Pa. in 1983.

Asexual reproduction of the new Miscanthus by divisions in Lancaster, Pa. since 2000, has shown that the unique features of this new Miscanthus are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Super Stripe has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Super Stripe’. These characteristics in combination distinguish ‘Super Stripe’ as a new and distinct cultivar of Miscanthus:

• • 1. Relatively compact, upright to somewhat outwardly spreading plant habit; dense and bushy growth habit.
  • 2. Vigorous growth habit.
  • 3. Green-colored leaves with yellow green-colored bands.
  • 4. Good garden performance.

In side-by-side comparisons conducted in Lancaster, Pa., plants of the new Miscanthus differed from plants of the female parent, the cultivar Zebrinus, in the following characteristics:

• • 1. Plants of the new Miscanthus were not upright and not as open as plants of the cultivar Zebrinus.
  • 2. Plants of the new Miscanthus were shorter than plants of the cultivar Zebrinus.
  • 3. Plants of the new Miscanthus had more yellow green-colored bands on the leaves than plants of the cultivar Zebrinus.

Plants of the new Miscanthus can be compared to plants of the Miscanthus cultivar Strictus, not patented. In side-by-side comparisons conducted in Lancaster, Pa., plants of the new Miscanthus differed from plants of the cultivar Strictus in the following characteristics:

• • 1. Plants of the new Miscanthus were not as upright as plants of the cultivar Strictus.
  • 2. Plants of the new Miscanthus were much shorter than plants of the cultivar Strictus.
  • 3. Plants of the new Miscanthus had more yellow green-colored bands on the leaves than plants of the cultivar Strictus.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Miscanthus. This photograph shows the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Miscanthus. The photograph comprises a side perspective view of typical two-year old plants of ‘Super Stripe’ grown in an outdoor nursery in Lancaster, Pa.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown in Pensacola, Fla. during the spring in an outdoor nursery and under conditions and practices which approximate those generally used in commercial Miscanthus production. During the production of the plants, day temperatures ranged from 21° C. to 35° C. and night temperatures ranged from 18° C. to 35° C. Measurements and numerical values for represent averages for typical six-month old plants grown in 10-cm containers.
