plant named ‘Florsalbro’

Abstract

A new and distinct Salvia cultivar named ‘Florsalbro’ is disclosed, characterized by a compact form, early flowering and abundant dark rose colored flowers. The new variety is a Salvia, normally produced as an outdoor garden or container plant.

Description

Latin name of the genus and species: Salvia nemerosa.

Variety denomination: ‘Florsalbro’.

BACKGROUND OF THE INVENTION

The new Salvia cultivar is a product of a planned breeding program conducted by the inventor, Tobias Bräunig, in Quedlinburg, Germany. The objective of the breeding program was to produce new Salvia varieties with denser plant habits, strong garden performance, in a range of flower colors. The open pollination resulting in this new variety was made during Summer of 2010.

The seed parent is an unpatented, proprietary, Salvia nemerosa. The pollen parent is unknown as it was an open pollination breeding program. The new variety was identified as a potentially interesting selection in Summer 2011, at a greenhouse in Quedlinburg, Germany.

Asexual reproduction of the new cultivar ‘Florsalbro’ by vegetative cuttings was first performed during 2011, at a research greenhouse in Quedlinburg, Germany. Subsequent propagation has shown that the unique features of this cultivar are stable and reproduced true to type on successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘Florsalbro’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘Florsalbro’ These characteristics in combination distinguish ‘Florsalbro’ as a new and distinct Salvia cultivar:

• • 1. Dark rose flower color.
  • 2. Compact plant form.
  • 3. Abundant flowering.
  • 4. Early flowering.

PARENT COMPARISON

Plants of the new cultivar ‘Florsalbro’ are similar to plants of the seed parent, in most horticultural characteristics, however, plants of the new cultivar ‘Florsalbro’ differ in the following:

• • 1. Dark rose flower color. The seed parent has a light rose colored flower.
  • 2. More vigorous growth rate.
  • 3. More abundant flowering.
  • 4. Earlier flowering.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘Florsalbro’ can also be compared to the commercial variety Salvia ‘Mainacht“, unpatented. These varieties are similar in most horticultural characteristics; however ‘Florsalbro’ differs in the following:

• • 1. More compact plant.
  • 2. More inflorescences per plant.
  • 3. Deeper bright rose color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘Florsalbro’, shown in an 8 inch commercial container.

FIG. 2 illustrates in full color typical flowers ‘Florsalbro’.

Plants were grown in a greenhouse. Santa Paula. Calif., in a commercial 8 inch container.

Age of the plant photographed is approximately 16 weeks from an unrooted cutting.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
