USPP17322P2 - Sedum plant named ‘Jaws’ - Google Patents

Abstract

A new cultivar of Sedum, Sedum ‘Jaws’, characterized by its blue-green foliage that is unique in having leaves with deep, sharp serrated margins that are cupped with curled edges. The leaves resemble shark's teeth.

Description

Botanical classification: Sedum hybrid.

Varietal denomination: ‘Jaws’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sedum of hybrid origin and will be referred to hereafter by its cultivar name, ‘Jaws’. ‘Jaws’ was derived from Sedum ‘Herbsfreude’ (not patented), also referred to in the trade as Sedum ‘Autumn Joy’. ‘Herbsfreude’ a hybrid of Sedum telephium and Sedum spectabilis.

The inventor discovered the new cultivar, ‘Jaws’, in a nursery in Lewisburg, Tenn. in 1999. ‘Jaws’ was discovered as a naturally occurring whole plant mutation as a single one gallon container found in a block of one gallon containers of ‘Herbsfreude’ that were originally derived from stem cuttings.

Sedum ‘Jaws’ is unique for its foliage in which the blue-green leaves have margins that are deeply and sharply serrated and are cupped and curled in orientation.

Asexual reproduction of the new cultivar was first accomplished by stem cuttings in Paw Paw, Mich. in summer of 2001 by the inventors. The new cultivar was subsequently propagated by tissue culture. The characteristics of the new cultivar have been determined to be stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar as observed on plants grown for three years outdoors in Paw Paw, Mich. These attributes in combination distinguish ‘Jaws’ from other varieties of Sedum known to the inventor.

• • 1. The leaves of ‘Jaws’ are deeply and sharply serrated, the parent plant, ‘Herbsfreude’, has leaves with margins that are smooth to finely toothed.
  • 2. The leaves of ‘Jaws’ are cupped in relation to the central vein and tend to curl.
  • 3. The foliage of ‘Jaws’ is blue-green with a heavy substance and waxy appearance.

BRIEF DESCRIPTION OF THE DRAWING

The plants and plant parts in the figures depict a two-year old plant of ‘Jaws’ as grown in a one-gallon container.

The photograph in FIG. 1 provides an overall view of ‘Jaws’ in bloom.

The photograph in FIG. 2 is a close up view of two typical leaves of ‘Jaws’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized. The color values cited in the detailed botanical description accurately describe the colors of the new Sedum.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of a two year-old plant of the new cultivar as grown outdoors in a one-gallon container in full sun. 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 2001 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
