USPP32414P2 - Sedum plant named ‘Gold Form’ - Google Patents

Abstract

A new and distinct cultivar of Sedum plant named ‘Gold Form’, characterized by its compact, dense and bushy growth habit; initially upright to trailing to weeping and decumbent plant habit; freely basally and laterally branching habit; yellow green-colored leaves; and good garden performance and winter hardiness.

Description

Botanical designation: Sedum rupestre.

Cultivar denomination: ‘GOLD FORM’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sedum plant, botanically known as Sedum rupestre and hereinafter referred to by the name ‘Gold Form’.

The new Sedum plant is a naturally-occurring branch mutation of Sedum rupestre ‘Angelina’, not patented. The new Sedum plant was discovered and selected by the Inventor on a single plant within a population of plants of ‘Angelina’ in a controlled greenhouse environment in Cardington, Ohio in 2014.

Asexual reproduction of the new Sedum plant by terminal vegetative cuttings in a controlled greenhouse environment in Cardington, Ohio since 2014 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 combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘Gold Form’. These characteristics in combination distinguish ‘Gold Form’ as a new and distinct Sedum plant:

• • 1. Compact, dense and bushy growth habit.
  • 2. Initially upright to trailing to weeping and decumbent plant habit.
  • 3. Freely basally and laterally branching habit.
  • 4. Yellow green-colored leaves; color is stable year-round.
  • 5. Good garden performance and winter hardiness.

Plants of the new Sedum differ from plants of the mutation parent, ‘Angelina’, primarily in the following characteristics:

• • 1. Plants of the new Sedum are more compact than and not as sprawling as plants of ‘Angelina’.
  • 2. Plants of the new Sedum are less vigorous than plants of ‘Angelina’.
  • 3. Plants of the new Sedum are more freely branching than plants of ‘Angelina’.
  • 4. Leaves of plants of the new Sedum maintain their yellow green color year-round whereas leaves of plants of ‘Angelina’ become more yellow during the summer and orange red in color in the winter.
  • 5. Plants of the new Sedum have not been observed to produce flowers whereas plants of ‘Angelina’ produce flowers during the summer.

Plants of the new Sedum can be compared to plants of Sedum rupestre ‘Lemon Ball’, not patented. Plants of the new Sedum and ‘Lemon Ball’ differ primarily in the following characteristics:

• • 1. Plants of the new Sedum are more rounded than and not as mounding as plants of ‘Lemon Ball’.
  • 2. Leaves of plants of the new Sedum are more green in color than and not as yellow as leaves of plants of ‘Lemon Ball’.
  • 3. Plants of the new Sedum are more winter hardy than plants of ‘Lemon Ball’.

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 plant of ‘Gold Form’ grown in a container.

The photograph on the second sheet is a close-up view of a typical plant of ‘Gold Form’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in 2.5-quart containers in an outdoor nursery in Elburn, Ill. and under cultural practices typical of commercial Sedum production. During the production of the plants, day temperatures ranged from 13° C. to 27° C., night temperatures ranged from 7° C. to 18° C. and light levels ranged from 5,000 to 8,000 foot-candles. Plants were 20 weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.

• Botanical classification: Sedum rupestre ‘Gold Form’.
