Abstract

A new and distinct cultivar of Sedum plant named ‘Yellow Xenox’, characterized by its upright and compact plant habit; basally branching habit; dense and bushy growth habit; attractive light yellow green-colored flowers; and good garden performance.

Description

Botanical designation: Hylotelephium spectabile.
Cultivar denomination: ‘Yellow 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 ‘Yellow 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 cultivars with numerous attractive flowers.
The new Sedum plant originated from a cross-pollination during the summer of 2005 in Rijpwetering, The Netherlands, of Sedum telephium ‘Xenox’, disclosed in U.S. Plant Pat. No. 16,888, as the female, or seed, parent with Sedum telephium ‘Sunkissed’, disclosed in U.S. Plant Pat. No. 16,927, as the male, or pollen, parent. The new Sedum 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 2006.
Asexual reproduction of the new Sedum plant by vegetative cuttings in a controlled environment in Rijpwetering, The Netherlands since the summer of 2006, 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 ‘Yellow Xenox’. These characteristics in combination distinguish ‘Yellow Xenox’ as a new and distinct cultivar of Sedum:
    • 1. Upright and compact plant habit.
    • 2. Basally branching habit; dense and bushy growth habit.
    • 3. Attractive light yellow green-colored flower.
    • 4. 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.
Plants of the new Sedum differ from plants of the male parent, ‘Sunkissed’ primarily in leaf color as plants of ‘Sunkissed’ have green to yellow green-colored leaves.
Plants of the new Sedum can be compared to plants of Sedum telephium ‘Bronco’, disclosed in U.S. Plant Pat. No. 18,085. Plants of the new Sedum and ‘Bronco’ differ in the following characteristics:
    • 1. Plants of the new Sedum are more compact than plants of ‘Bronco’.
    • 2. Plants of the new Sedum and ‘Bronco’ differ in leaf coloration.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Sedum plant, showing 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 Sedum plant.
The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Yellow Xenox’ grown in a container.
The photograph at the top of the second sheet is a close-up view of typical inflorescences of ‘Yellow Xenox’.
The photograph at the bottom of the second sheet is a close-up view of a typical leaf of ‘Yellow Xenox’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown in Rijpwetering, The Netherlands, under commercial practice during the late summer in an outdoor nursery with day temperatures ranging from 12° C. to 32° C. and night temperatures ranging from 6° C. to 18° C. Plants used in the photographs and description were two years old.
