STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR & APPLICANT/ASSIGNEE

The Inventor and Applicant/Assignee assert that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor and/or the Applicant/Assignee. Inventor and Applicant/Assignee claim a prior art exception under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Salvia plant, botanically known as Salvia dorrii x Salvia clevelandii and hereinafter referred to by the name ‘MSWNBoyton2’.

The new Salvia plant is a product of a planned breeding program conducted by the Inventor in Tucson, Ariz. The objective of the breeding program is to create new long-lived Salvia plants with high temperature tolerance, tolerance to dry and wet conditions and long flowering season.

The new Salvia plant originated from a cross-pollination conducted by the Inventor in May, 2016 of an unnamed selection of Salvia dorrii, not patented, as the female, or seed, parent with an unnamed selection of Salvia clevelandii, not patented, as the male, or pollen, parent. The new Salvia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled environment in Tucson, Ariz. in May, 2017.

Asexual reproduction of the new Salvia plant by softwood vegetative cuttings in Tucson, Ariz. since May, 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 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 ‘MSWNBoyton2’. These characteristics in combination distinguish ‘MSWNBoyton2’ as a new and distinct cultivar of Salvia:

• • 1. Relatively compact, upright and outwardly spreading plant habit.
  • 2. Freely branching habit and vigorous growth habit; bushy appearance.
  • 3. Greyish green-colored leaves.
  • 4. Relatively large inflorescences with violet blue-colored flowers.
  • 5 Long flowering period.
  • 6. Relatively tolerant to high temperatures and dry or wet conditions.

Plants of the new Salvia can be compared to plants of the female parent selection. Plants of the new Salvia differ from plants of the female parent selection in the following characteristics:

• • 1. Leaves of plants of the new Salvia are narrower and more oval and not as rounded as leaves of plants of the female parent selection.
  • 2. Plants of the new Salvia have larger inflorescences than plants of the female parent selection.
  • 3. Plants of the new Salvia are more tolerant to high temperature and wet conditions than plants of the female parent selection.

Plants of the new Salvia can be compared to plants of the male parent selection. Plants of the new Salvia differ from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Salvia are much shorter than plants of the male parent selection.
  • 2. Leaves of plants of the new Salvia are narrower than leaves of plants of the male parent selection.
  • 3. Plants of the new Salvia have larger inflorescences than plants of the male parent selection.
  • 4. Plants of the new Salvia tolerate wet conditions better than plants of the male parent selection.

Plants of the new Salvia can be compared to plants of an unnamed selection of Salvia greggii known to the Inventor, not patented. In side-by-side comparisons, plants of the new Salvia differed from plants of the unnamed selection of Salvia greggii in the following characteristics:

• • 1. Plants of the new Salvia have greyish green-colored leaves whereas plants of the unnamed selection of Salvia greggi have green-colored leaves.
  • 2. Plants of the new Salvia have larger inflorescences than plants of the unnamed selection of Salvia greggii.
  • 3. Plants of the new Salvia have violet blue-colored flowers whereas plants of the unnamed selection of Salvia greggii have pinkish red-colored flowers.
  • 4. Plants of the new Salvia are more tolerant to high temperatures than plants of the unnamed selection of Salvia greggii.

Plants of the new Salvia can also be compared to plants of an unnamed selection of Salvia chamaedryiodes known to the Inventor, not patented. In side-by-side comparisons, plants of the new Salvia differed from plants of the unnamed selection of Salvia chamaedryiodes in the following characteristics:

• • 1. Plants of the new Salvia have larger inflorescences than plants of the unnamed selection of Salvia chamaedryiodes.
  • 2. Plants of the new Salvia have violet blue-colored flowers whereas plants of the unnamed selection of Salvia chamaedryiodes have light blue-colored flowers.
  • 3. Plants of the new Salvia are more tolerant to wet conditions than plants of the unnamed selection of Salvia chamaedryiodes.
