plant name ‘Moonlight Serenade’

Abstract

A new and distinct cultivar of Sedum plant named ‘Moonlight Serenade’, characterized by its upright and compact plant habit; freely basally branching habit; dense and bushy growth habit; attractive white-colored flowers with greyed purple-colored apices; and good garden performance.

Description

Botanical designation: Hylotelephium spectabile.

Cultivar denomination: ‘MOONLIGHT SERENADE’.

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 ‘Moonlight Serenade’.

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 ‘Bronco’, disclosed in U.S. Plant Pat. No. 18,085, 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 ‘Moonlight Serenade’.

These characteristics in combination distinguish ‘Moonlight Serenade’ as a new and distinct cultivar of Sedum:

• • 1. Upright and compact plant habit.
  • 2. Freely basally branching habit; dense and bushy growth habit.
  • 3. Attractive white-colored flowers with greyed purple-colored apices.
  • 4. Good garden performance.

Plants of the new Sedum differ from plants of the female parent, ‘Xenox’, in the following characteristics:

• • 1. Plants of the new Sedum are more compact than and not as broad as plants of ‘Xenox’.
  • 2. Plants of the new Sedum have white-colored flowers with greyed purple-colored apices whereas plants of ‘Xenox’ have orange white to greyed yellow-colored flowers.

Plants of the new Sedum differ from plants of the male parent, ‘Bronco’, in the following characteristics:

• • 1. Plants of the new Sedum have smaller leaves than plants of ‘Bronco’.
  • 2. Plants of the new Sedum have white-colored flowers with greyed purple-colored apices whereas plants of ‘Bronco’ 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.
