plant named ‘SGRSA05-1’

Abstract

A new and distinct Salvia cultivar named ‘SGRSA05-1’ is disclosed, characterized by vigorous plants with a large, upright form and long flowering period. Flowers have salmon corollas with darker salmon-orange calyces. Calyces are persistent and retain their salmon-orange color. The new variety is a Salvia splendens, normally produced as an outdoor garden or container plant.

Description

Latin name of the genus and species: Salvia splendens.

Variety denomination: ‘SGRSA05-1’.

BACKGROUND OF THE INVENTION

The new Salvia cultivar is a product of a planned breeding program conducted by the inventor, Michael Uchneat in Bellefonte, Pa. The objective of the breeding program was to produce new Salvia splendens varieties with large, upright plant habits in a range of flower colors. The self-pollination resulting in this new variety was made during June of 2013.

The parent variety is an unpatented, proprietary, Salvia splendens referred to as ‘28669-1’. This parent variety was self-pollinated and the resulting seed collected. Seed collected from this self-pollination was grown out, with the result of a variety of flower colors and plant sizes observed among the seedling population. The new variety was identified as a potentially interesting selection, from this seedling population in August 2014, at a greenhouse in Bellefonte, Pa.

Asexual reproduction of the new cultivar ‘SGRSA05-1’ by vegetative cuttings was first performed during August of 2014, at a research greenhouse in Bellefonte, Pa. 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 ‘SGRSA05-1’ 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 ‘SGRSA05-1’ These characteristics in combination distinguish ‘SGRSA05-1’ as a new and distinct Salvia cultivar:

• 1. Vigorous, large, upright plant larger than most Salvia splendens in the trade.
• 2. Long flowering period from young plant until frost.
• 3. Calyces are persistent and color of the calyx is retained.
• 4. Unique flower color with a light salmon calyx with a darker salmon-orange corolla.

PARENT COMPARISON

Plants of the new cultivar ‘SGRSA05-1’ are similar to plants of the parent in most horticultural characteristics, however, plants of the new cultivar ‘SGRSA05-1’ differ in the following:

• 1. The new variety has a salmon and salmon-orange flower, the parent variety flower color is more red.
• 2. Size of the new variety is approximately 25% larger in size of than the parent variety.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘SGRSA05-1’ can also be compared to the commercial variety Salvia splendens ‘Saucy Red’, unpatented. These varieties are similar in most horticultural characteristics; however ‘SGRSA05-1’ differs in the following:

• 1. The new variety has salmon flowers. Flowers of ‘Saucy Red’ are solid red.
• 2. A higher percentage of calyx retention is observed in the new variety.
• 3. Foliage of the new variety is darker green.
• 4. The new variety is not sterile, whereas ‘Saucy Red’ appears to be sterile.

Plants of the new cultivar ‘SGRSA05-1’ can also be compared to the commercial variety Salvia splendens ‘Lighthouse Red’, unpatented. These varieties are similar in most horticultural characteristics; however ‘SGRSA05-1’ differs in the following:

• 1. The new variety has salmon flowers. Flowers of ‘Lighthouse Red’ are solid red.
• 2. Flowering spikes of the new variety are longer than those of ‘Lighthouse Red’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘SGRSA05-1’ grown in a greenhouse, in Santa Paula, Calif., in a commercial 10 inch container.

FIG. 2 illustrates in full color typical flowering spikes of ‘SGRSA05-1’. Age of the plant photographed is approximately 3 months from 3 rooted cuttings.

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.
