plant named ‘Pink Serenade’

Abstract

A new and distinct cultivar of Salvia plant named ‘Pink Serenade’, characterized by its upright plant habit; strong and vigorous growth habit; freely flowering habit; long racemes with light purple-colored flowers; and good garden performance.

Description

Botanical designation: Salvia sylvestris.

Cultivar denomination: ‘PINK SERENADE’.

BACKGROUND OF THE INVENTION

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

The new Salvia plant is a naturally-occurring branch mutation of Salvia sylvestris ‘Serenade’, not patented. The new Salvia plant was discovered and selected by the Inventor on a single flowering plant from within a population of plants of ‘Serenade’ in a controlled environment in Lisserbroek, The Netherlands in June, 2019.

Asexual reproduction of the new Salvia plant by softwood cuttings in Lisserbroek, The Netherlands, since June, 2019 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 environment 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 ‘Pink Serenade’. These characteristics in combination distinguish ‘Pink Serenade’ as a new and distinct cultivar of Salvia:

• • 1. Upright plant habit.
  • 2. Strong and vigorous growth habit.
  • 3. Freely flowering habit.
  • 4. Long racemes with light purple-colored flowers.
  • 5. Good garden performance.

Plants of the new Salvia can be compared to plants of the mutation parent, ‘Serenade’. Plants of the new Salvia differ primarily from plants of ‘Serenade’ in flower color as plants of the new Salvia have light purple-colored flowers whereas plants of ‘Serenade’ have mauve lilac-colored flowers.

Plants of the new Salvia can be compared to plants of ‘Pink Delight’, disclosed in U.S. Plant Pat. No. 14,965. In side-by-side comparisons, plants of the new Salvia differ from plants of ‘Pink Delight’ in the following characteristics:

• • 1. Plants of the new Salvia are taller than plants of ‘Pink Delight’.
  • 2. Plants of the new Salvia have longer inflorescences with more flowers than plants of ‘Pink Delight’.

Plants of the new Salvia can also be compared to plants of ‘Moulin Rouge’, disclosed in U.S. Plant Pat. No. 32,387. In side-by-side comparisons, plants of the new Salvia differ from plants of ‘Moulin Rouge’ in the following characteristics:

• • 1. Plants of the new Salvia are taller than plants of ‘Moulin Rouge’.
  • 2. Plants of the new Salvia have longer inflorescences with more flowers than plants of ‘Moulin Rouge’.
  • 3. Flowers of plants of the new Salvia are lighter purple in color than flowers of plants of ‘Moulin Rouge’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Salvia 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 actual colors of the new Salvia plant.

The photograph on the first sheet (FIG. 1) comprises a side perspective view of a typical flowering plant of ‘Pink Serenade’ grown in a container.

The photograph on the second sheet (FIG. 2) is a close-up view of a typical inflorescence of ‘Pink Serenade’.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following description were grown under conditions which closely approximate commercial Salvia production conditions in June in 9-cm containers in an outdoor nursery in Lisserbroek, The Netherlands. During the production of the plants, day temperatures ranged from 12° C. to 25° C. and night temperatures ranged from 4° C. to 12° C. Plants were two months from planting 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.
