plant named ‘Orange Xenox’

Abstract

A new and distinct cultivar of Sedum plant named ‘Orange Xenox’, characterized by its upright plant habit; basally branching habit; dense and bushy growth habit; greyed purple to brown-colored leaves; numerous orange-colored flowers; and good garden performance.

Description

Botanical designation: Hylotelephium spectabile.

Cultivar denomination: ‘ORANGE XENOX’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sedum plant, botanically known as Hylotelephium spectabile and hereinafter referred to by the name ‘Orange Xenox’.

The new Sedum plant is a product of a planned breeding program conducted by the Inventor in Rijpwetering, The Netherlands. The objective of the breeding program is to create new strong and healthy Sedum plants with numerous attractive flowers.

The new Sedum plant originated from a cross-pollination during the summer of 2007 in Rijpwetering, The Netherlands, of Hylotelephium spectabile ‘Xenox’, disclosed in U.S. Plant Pat. No. 16,888, as the female, or seed, parent with Hylotelephium spectabile ‘Sunkissed’, disclosed in U.S. Plant Pat. No. 16,927, as the male, or pollen, parent. The new Sedum plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Rijpwetering, The Netherlands during the summer of 2008.

Asexual reproduction of the new Sedum plant by vegetative cuttings in a controlled environment in Rijpwetering, The Netherlands since the summer of 2008, has shown that the unique features of this new Sedum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Sedum 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 ‘Orange Xenox’. These characteristics in combination distinguish ‘Orange Xenox’ as a new and distinct Sedum plant:

• • 1. Upright plant habit.
  • 2. Basally branching habit; dense and bushy growth habit.
  • 3. Greyed purple to brown-colored leaves.
  • 4. Numerous orange-colored flowers.
  • 5. Good garden performance.

Plants of the new Sedum differ from plants of the female parent, ‘Xenox’, primarily in flower color as plants of ‘Xenox’ have orange white to greyed yellow-colored flowers. In addition, plants of the new Sedum have darker-colored leaves than plants of ‘Xenox’.

Plants of the new Sedum differ from plants of the male parent, ‘Sunkissed’, primarily in flower color as plants of ‘Sunkissed’ have yellow-colored flowers. In addition, plants of the new Sedum and ‘Sunkissed’ differ in leaf color.

Plants of the new Sedum can also be compared to plants of Hylotelephium spectabile ‘Yellow Xenox’, disclosed in U.S. Plant Pat. No. 21,528. Plants of the new Sedum and ‘Yellow Xenox’ differ primarily in flower color as plants of ‘Yellow Xenox’ have yellow-colored flowers. In addition, plants of the new Sedum and ‘Yellow Xenox’ differ in leaf color.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the late summer in ground beds in an outdoor nursery in Rijpwetering, The Netherlands and under commercial practice. During the production of the plants, day temperatures ranged from 12° C. to 32° C. and night temperatures ranged from 6° C. to 18° C. Plants were two years old when the photographs and description were taken.
