USPP22345P2 - Cordyline plant named ‘Spricorhapso’ - Google Patents

Abstract

A new and distinct cultivar of Cordyline plant named ‘Spricorhapso’, characterized by its upright and outwardly slanting growth habit; vigorous growth habit and relatively rapid growth rate; long lanceolate variegated leaves with brown, greyed red, light orange white-colored longitudinal stripes; tolerance to low and high temperatures; excellent keeping quality and good garden performance.

Description

Botanical designation: Cordyline australis.

Cultivar denomination: ‘SPRICORHAPSO’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Cordyline plant, botanically known as Cordyline australis, and hereinafter referred to by the name ‘Spricorhapso’.

The new Cordyline plant is a naturally-occurring whole plant mutation of the Cordyline australis ‘Red Star’, not patented. The new Cordyline plant was discovered and selected by the Inventor within a population of plants of ‘Red Star’ in a controlled greenhouse environment in Zhejiang, China on Apr. 2, 2004.

Asexual reproduction of the new Cordyline plant by micropropagated cuttings in Zhejiang, China since April, 2004, has shown that the unique features of this new Cordyline plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Cordyline have 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 ‘Spricorhapso’. These characteristics in combination distinguish ‘Spricorhapso’ as a new and distinct cultivar of Cordyline plant:

• • 1. Upright and outwardly slanting growth habit.
  • 2. Vigorous growth habit and relatively rapid growth rate.
  • 3. Long lanceolate variegated leaves with brown, greyed red, light orange white-colored longitudinal stripes.
  • 4. Tolerant to low and high temperatures.
  • 5. Excellent keeping quality and good garden performance.

Plants of the new Cordyline differ from plants of the parent, ‘Red Star’, primarily in leaf color as plants of ‘Red Star’ have dark burgundy red-colored leaves.

Plants of the new Cordyline can be compared to plants of the Cordyline australis ‘Sunrise’, disclosed in U.S. Plant Pat. No. 20,634. In side-by-side comparisons conducted in Wamberal, New South Wales, Australia, plants of the new Cordyline differed primarily from plants of the ‘Sunrise’ in the following characteristics:

• • 1. Plants of the new Cordyline were more vigorous than plants of ‘Sunrise’.
  • 2. Plants of the new Cordyline were shorter and broader than plants of ‘Sunrise’.
  • 3. Leaves of plants of the new Cordyline were more upright than and not as weeping as leaves of plants of ‘Sunrise’.
  • 4. Plants of the new Cordyline and ‘Sunrise’ differed in leaf coloration as plants of ‘Sunrise’ had red and brown-colored leaves.

Plants of the new Cordyline can also be compared to plants of the Cordyline australis ‘Southern Splendour’, disclosed in U.S. Plant Pat. No. 19,102. In side-by-side comparisons conducted in Wamberal, New South Wales, Australia, plants of the new Cordyline differed primarily from plants of the ‘Southern Splendour’ in the following characteristics:

• • 1. Leaves of plants of the new Cordyline were more upright than and not as weeping as leaves of plants of ‘Southern Splendour’.
  • 2. Plants of the new Cordyline and ‘Southern Splendour’ differed in leaf coloration as plants of ‘Southern Splendour’ had pink and brown-colored leaves.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Cordyline plant. This photographs show the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Cordyline plant.

The photograph on the first sheet comprises side and top perspective views of typical plants of ‘Spricorhapso’ grown in containers.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the winter in 14-cm containers in an outdoor nursery in Wamberal, New South Wales, Australia and under conditions and practices which approximate those generally used in commercial Cordyline plant production. During the production of the plants, day temperatures ranged from 14° C. to 35° C., night temperatures ranged from 5° C. to 22° C. and light levels averaged 100,000 lux. Plants were one year old when the photographs and the botanical description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
