plant named ‘Razzleberry’

Abstract

A new cultivar of Sedum plant named ‘Razzleberry’ characterized by its very compact plant habit with stems that do not flop, its size of about 22 cm (9 inches) in height and 46 cm (18 inches) in spread, its very large inflorescences up to 22 cm (9 inches) in diameter, its flowers that are dark raspberry red in color, its foliage that emerges gray-blue in spring and turns to dark purple-black in mid summer, its very early blooming season, and its resistance to Sedum foliage blight.

Description

Botanical classification: Sedum hybrid.

Variety denomination: ‘Razzleberry’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sedum plant of hybrid origin known as Sedum ‘Razzleberry’ and will be referred to hereinafter by its cultivar name, ‘Razzleberry’. The new cultivar of Sedum is a hardy herbaceous perennial grown for use as a landscape and container plant with particular use as a groundcover.

‘Razzleberry’ arose from an ongoing breeding program conducted by the Inventor in Hudsonville, Mich. The goal of the breeding program is to produce new groundcover type cultivars of Sedum with compact, mounding, plant habits without the tendency to flop combined with abundant, large, and brightly colored flowerheads.

The inventor made a cross in September 2009 between an unnamed plant from the Inventor's breeding program as the female parent, and Xenox (U.S. Plant Pat. No. 16,888) as the male parent. ‘Razzleberry’ was selected as a single unique plant in August 2010 amongst the seedlings that resulted from the above cross.

Asexual reproduction of the new cultivar was first accomplished by tip cuttings in September of 2010 in Hudsonville, Mich. Propagation by cuttings has determined the characteristics are 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 ‘Razzleberry’ as a unique cultivar of Sedum.

• • 1. ‘Razzleberry’ exhibits a very compact plant habit with stems that do not flop.
  • 2. ‘Razzleberry’ reaches about 22 cm (9 inches) in height and 46 cm (18 inches) in spread.
  • 3. ‘Razzleberry’ exhibits very large inflorescences up to 22 cm (9 inches) in diameter.
  • 4. ‘Razzleberry’ exhibits flowers that are dark raspberry red in color.
  • 5. ‘Razzleberry’ exhibits foliage that emerges gray-blue in spring and turns to dark purple-black in mid summer.
  • 6. ‘Razzleberry’ blooms very early in the season.
  • 7. ‘Razzleberry’ has been observed to be highly resistant to Sedum foliage blight.

‘Razzleberry’ can be compared to its parent plants. The female parent differs from ‘Razzleberry’ in having a plant size that is half the size (reaches 10 cm in height), inflorescences that are much smaller in size (5 cm in diameter), smaller leaves, and gray-green foliage that does not change to purple-black in summer. The male parent, Xenox differs from ‘Razzleberry’ in being larger in size and less compact, in having flowers that are light pink in color, and in having larger leaves. ‘Razzleberry’ can also be most closely compared to the cultivars ‘Sunset Cloud’ (not patented) and ‘Rosy Glow’ (not patented). ‘Sunset Cloud’ and ‘Rosy Glow’ differ from ‘Razzleberry’ in being taller in height, in having an open and floppy plant habit with age, in having smaller inflorescences with fewer flowers per inflorescence, and in having smaller, thinner leaves with longer internode lengths.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Sedum. The photographs were taken of 2 year-old plants of ‘Razzleberry’ as grown in the ground in full sun in Hudsonville, Mich.

The photograph in FIG. 1 provides a view of the plant habit of several plants of ‘Razzleberry’.

The photograph in FIG. 2 provides a comparison between blooming stems of ‘Razzleberry’ (bottom), ‘Sunset Cloud’ (center) and ‘Rosy Glow’ (top).

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

The following is a detailed description of the new cultivar as observed on 2 year-old plants of ‘Razzleberry’ as grown in a garden in full sun in New Hope, Minn. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
