The first non-enabling disclosure of the new plant, in the form of a photograph and brief description was in website managed by Walters Gardens, Inc. on Feb. 1, 2020 followed by the “Walters Gardens 20-21 Catalog” first distributed on May 20, 2020. The claimed plant was first sold on Jun. 29, 2020 by Walters Gardens, Inc., who obtained the new plant and all information relating thereto from the inventor. No plants of Salvia ‘Tidal Pool’ have been sold in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior to the filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor.BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of perennial Salvia plant hereinafter referred to by the cultivar name Salvia ‘Tidal Pool’ or as the new plant. The new plant was from a cross between ‘Azure Snow’ U.S. Plant Pat. No. 30,534 and ‘Crystal Blue’ U.S. Plant Pat. No. 26,344 on Jun. 20, 2015 at a wholesale perennial nursery in Zeeland, Mich., USA. Seed was collected in the summer of 2015 and sown at the same nursery. The new plant was initially evaluated in the summer of 2016 and assigned the breeder code 15-24-5 through the trial process prior to assigning a cultivar name.
The new Salvia was further evaluated and asexually propagated initially by division and later by basal cuttings taken at the same nursery in Zeeland, Mich., USA in 2017. Evaluation of these and further cutting grown plants shows that Salvia ‘Tidal Pool’ continues to be stable and produce true to type plants in successive generations of asexual propagation.SUMMARY OF THE INVENTION
Plants of Salvia ‘Tidal Pool’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, nutrition and light intensity without, however, any variance in genotype.
‘Tidal Pool’ can be closely compared to ‘Blue Hill’ (not patented), ‘May Night’ (not patented), ‘Violet Profusion’ U.S. Plant Pat. No. 31,467, ‘Indiglo Girl’ U.S. Plant Pat. No. 31,254, ‘Midnight Model’ U.S. Plant Pat. No. 29,498 and ‘Violet Riot’ U.S. Plant Pat. No. 26,273.
‘Blue Hill’ has similar height but narrower in width with less branching of the peduncles and the flower color is a lighter bluish-violet. ‘May Night’ has a more upright habit with smaller flowers per inflorescence of deep violet-purple. ‘Violet Profusion’ has flowers that are violet-blue with rosy-purple calyxes with a shorter habit. ‘Indiglo Girl’ has slightly taller habit and flowers of indigo-blue with dark calyxes. ‘Midnight Model’ has flowers that are more violet-blue with a slightly larger and less rounded habit. ‘Violet Riot’ has more compact flowering of vivid violet-blue flowers on taller inflorescences.
The female parent, ‘Azure Snow’ has similar height, but the flowers are larger and bicolor with deep violet-blue and white. The male parent, ‘Crystal Blue’, has a similar habit to the new plant, but the flowers are light sky-blue.
The following characteristics in combination distinguish Salvia ‘Tidal Pool’ as a new and distinct cultivar from all other cultivars known to the inventor:
- 1. Large, violet-blue flowers with lighter blue interiors densely arranged in verticils;
- 2. Stiff, low, broad, rounded, habit of heavily-branched stems;
- 3. Dark violet-blue flower buds and calyxes strongly blushed with dark greyed-red;
- 4. Medium height, compact, strong, vigorous and winter-hardy habit;
- 5. Rugose gray-green foliage.
The photographs of the new plant demonstrate the unique traits and the overall appearance of Salvia ‘Tidal Pool’. The colors are as accurate as reasonably possible with color reproductions. Variation in ambient light spectrum, source and direction may cause the appearance of minor variation in color. The plant used in the photographs was a three-year-old plant grown in an open, full-sun trial garden at a wholesale perennial nursery in Zeeland, Mich. with supplemental water and fertilizer when needed.
The following descriptions and color references except where common dictionary terms are used are based on the 2015 edition of The Royal Horticultural Society Colour Chart. Salvia ‘Tidal Pool’ has not been observed under all possible environments. The phenotype may vary slightly with different growing environments such as temperature, light, fertility, soil pH, moisture and plant maturity levels, but without any change in the genotype. The following observations and size descriptions are based on two-year old plants growing in an outdoor full-sun trial garden at a wholesale perennial nursery in Zeeland, Mich. Plants were given supplemental water and fertilizer and plant growth regulators were used for the greenhouse trials only.
