plant named ‘DSALAXBL’

Abstract

A new and distinct cultivar of Salvia plant named ‘DSALAXBL’ is disclosed, characterized by early flowering on compact, upright plants. Plants flower abundantly, producing violet-blue flowers with uniquely colored sepals of purple and green. 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: ‘DSALAXBL’.

BACKGROUND OF THE INVENTION

The new Salvia cultivar is the product of a planned breeding program conducted by the inventor, Gavriel Danziger, in Moshav Mishmar Hashiva, Israel. The objective of the breeding program was to produce new Salvia varieties for ornamental commercial applications. The open pollination resulting in this new variety was made in August 2016.

The seed parent is an, unpatented, unnamed proprietary Salvia nemerosa ‘SAN-13-2959’. The pollen parent is unknown as it was an open pollination breeding program. The new variety was discovered in June 2017 by the inventor in a group of seedlings resulting from the 2016 open pollination, in a research greenhouse in Moshav Mishmar Hashiva, Israel.

Asexual reproduction of the new cultivar was performed by vegetative cuttings. This was first performed at a research greenhouse in Moshav Mishmar Hashiva, Israel in September 2017, and has shown that the unique features of this cultivar are stable and reproduced true to type in multiple successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘DSALAXBL’ 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 ‘DSALAXBL’ These characteristics in combination distinguish ‘DSALAXBL’ as a new and distinct Salvia cultivar:

• • 1. Compact and upright habit.
  • 2. Early flowering.
  • 3. Abundant flowers.
  • 4. Violet-blue flowers.
  • 5. Uniquely purple and green colored sepals.

PARENTAL COMPARISON

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

• • 1. The seed parent has longer foliage than the new variety.
  • 2. The seed parent flowers less abundantly than the new variety.
  • 3. The seed parent has longer flowering stems than the new variety.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘DSALAXBL’ are comparable to the commercial variety Salvia x sylvestris ‘DSALRS203’, U.S. Plant Pat. No. 26,520. The two Salvia varieties are similar in most horticultural characteristics; however, the new variety ‘DSALAXBL’ differs in the following:

• • 1. This comparator blooms one week earlier than the new variety.
  • 2. This comparator has lighter blue petals than the new variety.
  • 3. This comparator has wider foliage than the new variety.

Plants of the new cultivar ‘DSALAXBL’ can also be comparable to the unpatented commercial variety Salvia ‘Sallyrosa Pink’. The two Salvia varieties are similar in most horticultural characteristics; however, the new variety ‘DSALAXBL’ differs in the following:

• • 1. This comparator has pink flowers, while the new variety has violet-blue flowers.
  • 2. This comparator has a more erratic growth habit than the new variety.
  • 3. This comparator has green sepals, while the new variety has purple and green sepals.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘DSALAXBL’ grown in 25 cm pot outdoors in Moshav Mishmar Hashiva, Israel. Age of the plant photographed is approximately 4 months from a rooted cutting.

FIG. 2 illustrates multiple inflorescences from the same plant as FIG. 1.

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.
