plant named ‘Rainbow Xenox’

Abstract

A new and distinct cultivar of Sedum plant named ‘Rainbow Xenox’, characterized by its upright plant habit; sturdy and strong branches; attractive greyed purple-colored flowers; and good garden performance.

Description

Botanical designation: Hylotelephium spectabile.

Cultivar denomination: ‘RAINBOW 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 ‘Rainbow 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 an open-pollination during the summer of 2004 in Rijpwetering, The Netherlands, of an unnamed selection of Hylotelephium spectabile, not patented, as the female, or seed, parent with an unknown selection of Hylotelephium spectabile, not patented, 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 open-pollination in a controlled greenhouse environment in Rijpwetering, The Netherlands during the summer of 2005.

Asexual reproduction of the new Sedum plant by vegetative cuttings in a controlled environment in Rijpwetering, The Netherlands since the summer of 2005, 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 ‘Rainbow Xenox’. These characteristics in combination distinguish ‘Rainbow Xenox’ as a new and distinct cultivar of Sedum:

• • 1. Upright plant habit.
  • 2. Sturdy and strong branches.
  • 3. Attractive greyed purple-colored flowers.
  • 4. Good garden performance.

Plants of the new Sedum differ from plants of the female parent selection primarily in flower color as plants of the female parent selection have yellow green-colored flowers.

Plants of the new Sedum can be compared to plants of Sedum telephium ‘Sunkissed’, disclosed in U.S. Plant Pat. No. 16,927. Plants of the new Sedum and ‘Sunkissed’ differ primarily in flower color as plants of ‘Sunkissed’ have yellow-colored flowers.

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 ‘Rainbow Xenox’ grown in a container.

The photograph at the top of the second sheet is a close-up view of typical inflorescences of ‘Rainbow Xenox’.

The photograph at the bottom of the second sheet is a close-up view of a typical leaf of ‘Rainbow Xenox’.
