USPP36953P2 - Salvia plant named ‘DWSahyb03’ - Google Patents

Abstract

A new and distinct cultivar of Salvia plant named ‘DWSahyb03’, characterized by its mostly upright to somewhat outwardly spreading plant habit; vigorous growth habit and rapid growth rate; freely branching habit; dense and bushy appearance; dark green-colored leaves; freely flowering habit; long and erect inflorescences with numerous bright red-colored flowers; and excellent container and garden performance.

Description

Botanical designation: Salvia coccinea.

Cultivar denomination: ‘DWSahyb03’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Salvia plant, botanically known as Salvia coccinea and hereinafter referred to by the name ‘DWSahyb03’.

The new Salvia plant is a naturally-occurring whole plant mutation of Salvia coccinea ‘Forest Fire’, not patented. The new Salvia plant was discovered and selected by the Inventors as a single flowering plant from within a population of plants of ‘Forest Fire’ in a controlled greenhouse environment in Sandton, Gauteng, South Africa in July 2016.

Asexual reproduction of the new Salvia plant by vegetative terminal cuttings in Sandton, Gauteng, South Africa since February 2017 has shown that the unique features of this new Salvia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Salvia 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 ‘DWSahyb03’. These characteristics in combination distinguish ‘DWSahyb03’ as a new and distinct Salvia plant:

• • 1. Mostly upright to somewhat outwardly spreading plant habit.
  • 2. Vigorous growth habit and rapid growth rate.
  • 3. Freely branching habit; dense and bushy appearance.
  • 4. Dark green-colored leaves.
  • 5. Freely flowering habit.
  • 6. Long and erect inflorescences with numerous bright red-colored flowers.
  • 7. Excellent container and garden performance.

Plants of the new Salvia can be compared to plants of the mutation parent, ‘Forest Fire’. Plants of the new Salvia differ primarily from plants of ‘Forest Fire’ in the following characteristics:

• • 1. Plants of the new Salvia are more compact than plants of ‘Forest Fire’.
  • 2. Plants of the new Salvia have shorter internodes than plants of ‘Forest Fire’.
  • 3. Plants of the new Salvia have thicker leaves than plants of ‘Forest Fire’.
  • 4. Plants of the new Salvia have larger flowers than plants of ‘Forest Fire’.

Plants of the new Salvia can be compared to plants of Salvia coccinea ‘Lady in Red’, not patented. In side-by-side comparisons, plants of the new Salvia differ from plants of ‘Lady in Red’ in the following characteristics:

• • 1. Plants of the new Salvia are more compact than plants of ‘Lady in Red’.
  • 2. Plants of the new Salvia have shorter internodes than plants of ‘Lady in Red’.
  • 3. Plants of the new Salvia have thicker leaves than plants of ‘Lady in Red’.
  • 4. Plants of the new Salvia have larger flowers than plants of ‘Lady in Red’.

Plants of the new Salvia can also be compared to plants of Salvia coccinea ‘Yucatan’, not patented. In side-by-side comparisons, plants of the new Salvia differ from plants of ‘Yucatan’ in the following characteristics:

• • 1. Plants of the new Salvia are more compact than plants of ‘Yucatan’.
  • 2. Plants of the new Salvia have shorter internodes than plants of ‘Yucatan’.
  • 3. Plants of the new Salvia have thicker leaves than plants of ‘Yucatan’.
  • 4. Plants of the new Salvia have larger flowers than plants of ‘Yucatan’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the late winter and early spring in 10.75-cm containers in a glass-covered greenhouse in Loudon, New Hampshire and under cultural practices typical of commercial Salvia production.
