plant named ‘Nonag’

Abstract

A new cultivar of Sedum plant, ‘Nonag’, characterized by its glossy foliage that emerges shiny green in color, holding this color during summer, then changing to a mahogany color during fall and winter, its green stems, its flowers in late spring and early summer that are bright lemon yellow and held upon rounded somewhat drooping inflorescences atop a dense, low growing plant habit.

Description

Botanical classification: Sedum kamtschaticum var. floriferum.

Variety denomination: ‘Nonag’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application is co-pending with a U.S. Plant Patent Applications by the same Inventory and pertain to plants derived from the same parentage, the applications are entitled Sedum Plant named ‘Nonof’ (U.S. Plant patent application Ser. No. 13/200,871), and Sedum Plant named ‘Nonel’ (U.S. Plant patent application Ser. No. 13/200,893).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sedum plant, botanically known as Sedum kamtschaticum var. floriferum ‘Nonag’ and will be referred to hereinafter by its cultivar name, ‘Nonag’. The new cultivar of Sedum is a hardy herbaceous perennial grown for use as a landscape and container plant and is particularly suitable as a ground cover.

‘Nonag’ was discovered in March of 2009 as a naturally occurring whole plant mutation in the Inventor's nursery in Nunica, Mich. as a single unique plant in a field planted with 50,000 seedlings from unnamed plants of Sedum kamtschaticum var. floriferum.

Asexual reproduction of the new cultivar was first accomplished by stem cuttings in June of 2009 in Nunica, Mich. Propagation by cuttings and crown division has determined the characteristics to be stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the characteristics of the new cultivar. These attributes in combination distinguish ‘Nonag’ as a unique cultivar of Sedum.

• • 1. ‘Nonag’ exhibits foliage that emerges shiny green and stays shiny green throughout summer, then turns a distinct mahogany color during fall, and winter.
  • 2. ‘Nonag’ exhibits flower buds that are bright yellow.
  • 3. ‘Nonag’ exhibits numerous, rounded, somewhat drooping inflorescences with flowers of bright lemon yellow during early summer.
  • 4. ‘Nonag’ exhibits a dense, low growing habit with foliage that reaches 6 to 7 inches in height.

The exact parent plant of ‘Nonag’ is unknown, however the plants in the field block Sedum kamtschaticum var. floriferum in which ‘Nonel’ was discovered has foliage that reached 5 inches in height and foliage that is maroon in color during the fall and winter months. ‘Nonel’ can be compared to other cultivars of Sedum kamtschaticum var. floriferum (all un-patented) which differ from ‘Nonel’ in the following characteristics; ‘Czar's Gold’ differs in having red stems, shorter and broader foliage, a mature height of 5 inches, and sparsely borne rounded inflorescences; ‘Weihenstephaner Gold’ differs in having red stems, and narrower and longer foliage which turns bronze during the fall and winter months.

‘Nonag’ can be compared to other cultivars selected from the same field of seedlings; ‘Nonof’ and ‘Nonel’. ‘Nonof’ differs from ‘Nonag’ in having foliage that in shiny green and remains shiny green in the fall and winter and in reaching 4.5 inches in height. ‘Nonel’ differs from ‘Nonag’ in having foliages that turns deep red-purple during fall and winter and reaches 4 inches in height.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photograph illustrates the overall appearance and distinct characteristics of the new Sedum. The photograph was taken of a 2 year-old plants of ‘Nonag’ as grown in the ground in full sun in Nunica, Mich.

The photograph in FIG. 1 illustrates the unique foliage coloration of ‘Nonag’.

The 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.

DETAILED BOTANICAL DESCRIPTION
