plant named ‘Rhythm and Blues’

Abstract

A new cultivar of Salvia named ‘Rhythm & Blues’ that is distinguishable by large flowers which are intense deep-purple in color, which are borne in profusion on naturally branching plants with season-long deep green foliage is disclosed.

Description

Genus and species: Salvia x guaranitica.

Variety denomination: ‘Rhythm & Blues’.

BACKGROUND

The present disclosure relates to a new and distinct cultivar of Salvia plant, also known as a sage, a perennial that is grown for use as an ornamental landscape and container plant. The new variety is known botanically as Salvia x guaranitica and will be referred to hereinafter by the cultivar name ‘Rhythm & Blues’.

‘Rhythm & Blues’ was selected in 2015 from a population of seedlings which the inventor raised from seed collected from plants resulting from the controlled hybridization between a plant of Salvia x guaranitica var violacea (species, unpatented) as male parent, and a plant of Salvia x guaranitica var purpurea (species, unpatented) as female parent. The hybridization and selection was carried out by the inventor at the inventor's nursery in Elk, Calif.

‘Rhythm and Blues’ was selected by the inventor for its combination of flower count, flower size, intensity of flower color, deep green foliage and naturally compact and branching plant habit.

‘Rhythm & Blues’ was first asexually propagated in 2015 in a greenhouse at the inventor's nursery in Elk, Calif. using softwood tip cuttings. The inventor has determined during successive cycles of asexual propagation that ‘Rhythm & Blues’ is stable and reproduces true to type.

SUMMARY

The following traits have been repeatedly observed and represent the distinguishing characteristics of ‘Rhythm & Blues’. ‘Rhythm & Blues’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, without however, any variance in genotype.

• • 1. ‘Rhythm & Blues’ exhibits a compact well-branched upright plant habit;
  • 2. The flowers of ‘Rhythm & Blues’ are vibrant violet-blue in color;
  • 3. ‘Rhythm & Blues’ grows and flowers rapidly. Flowering plants may be produced in 10 to 12 weeks from a cutting.
  • 4. The calyces of the flowers of ‘Rhythm & Blues’ range in color from very dark purple to black. The calyces are black in conditions of full sunlight.
  • 5. ‘Rhythm & Blues’ produces new flowering stems continuously from spring to fall.
  • 6. The foliage of ‘Rhythm & Blues’ is dark green in color at all stages of growth.
  • 7. The leaves of ‘Rhythm & Blues’ are thick and robust.

DESCRIPTION OF THE PHOTOGRAPHS

The accompanying color photographs illustrate the overall appearance of the new Salvia cultivar ‘Rhythm & Blues’ showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. The photographs were taken in spring and summer 2017 from plants which were growing out of doors in Oxnard, Calif. The plants had received one pinch after initial cutting establishment. Colors in the photographs may differ from the color values cited in the detailed botanical description, which more accurately describes the actual colors of the new variety ‘Rhythm & Blues’.

COMPARISON WITH PARENTAL LINES AND KNOWN VARIETY

‘Rhythm & Blues’ is distinguishable from each of its parents by the color and texture of its foliage which is deeper green and thicker than either parent and by the larger size and quantity and the deeper and more intense color of its flowers.

The variety of Salvia x guaranitica which the inventor considers to be most similar to ‘Rhythm & Blues’ is Salvia ‘Black and Blue’ (unpatented). In comparison with ‘Black and Blue’, ‘Rhythm & Blues’ exhibits thicker and darker green foliage and larger flowers borne in greater profusion and more intensely deep purple in color. The foliage of ‘Black and Blue’ is prone to yellowing as the season proceeds. The flowers of ‘Black & Blue’ are blue-purple in color.
