plant named ‘Ignition Cranberry’

Abstract

A new cultivar of Salvia named ‘Ignition Cranberry’ that is distinguishable by compact, low-growing plant habit and saturated blood red colored flowers.

Description

Genus and species: Salvia x jamensis.

Variety denomination: ‘Ignition Cranberry’.

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 jamensis and will be referred to hereinafter by the cultivar name ‘Ignition Cranberry’.

‘Ignition Cranberry’ originated and was selected from a population of hybrid seedlings from a Salvia breeding program, which was started in 2010. The breeding program was conducted in the inventor's greenhouse nursery in Elk, Calif. The aim of the breeding program is to develop a uniform series of compact free-flowering varieties of Salvia x jamensis each with similar plant habits and flowering characteristics but with distinctly different flower colors. ‘Ignition Cranberry’ was selected by the inventor in 2019 from seedlings which resulted from the controlled hybridization using pollen collected from assembled selections from the inventor's large collection of Salvia varieties. The inventor applied the collected pollen to a selected unnamed female parent which bore red flowers. Seed from the female parent was grown out, and one seedling, which was named ‘Ignition Cranberry’, was selected for its saturated blood red colored flowers which were borne on compact low-growing plants with mid-green glossy leaves.

‘Ignition Cranberry’ was first asexually propagated in 2020 in a greenhouse at the inventor's nursery in Elk, Calif. using softwood tip cuttings. The inventor has confirmed that ‘Ignition Cranberry’ is stable and reproduces true to type in successive generations of asexual reproduction.

SUMMARY

The following traits have been repeatedly observed and represent the distinguishing characteristics of ‘Ignition Cranberry’. ‘Ignition Cranberry’ 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. ‘Ignition Cranberry’ exhibits a compact low-growing well-branched plant habit.
  • 2. The flowers of ‘Ignition Cranberry’ are saturated blood red in color.
  • 3. ‘Ignition Cranberry’ grows and flowers rapidly. Flowering plants may be produced in 10 to 12 weeks from a cutting.

DESCRIPTION OF THE PHOTOGRAPHS

The accompanying color photographs illustrate the overall appearance of the new Salvia cultivar ‘Ignition Cranberry’ showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Photographs were taken in March 2022 in Santa Barbara, Calif. from a one-year-old plant grown outdoors in a 3.7-gallon (14 liter) container, with one pinch after initial cutting establishment and without any chemical growth regulators. 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 ‘Ignition Cranberry’.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘Ignition Cranberry’. Observations, measurements, values, and comparisons were collected in March 2022 in Santa Barbara, Calif. from a one year old plant which had been growing outdoors in full sun in a 3.7 gallon (14 liter) container in Santa Barbara, Calif., with one pinch after initial cutting establishment and without any chemical growth regulators. Color determinations were made in accordance with The 2007 Royal Horticultural Society Colour Chart from London England, except where general color terms of ordinary dictionary significance are used.

COMPARISON WITH PARENTAL LINES AND KNOWN VARIETY

In comparison with the assembled pollen donor varieties, ‘Ignition Cranberry’ exhibits a distinct combination of vigorous growth, profuse branching and saturated red flowers. None of the assembled pollen donor varieties, nor the selected female parent, exhibits the saturated blood red color of the flowers of ‘Ignition Cranberry’.

‘Ignition Cranberry’ is closest in plant habit to the inventor's varieties Salvia ‘Ignition Purple’ (U.S. Plant Pat. No. 27,788) and Salvia ‘Ignition Fuchsia’ (U.S. Plant Pat. No. 32,046). The closest known variety of Salvia which bears similarly deep red flowers is Salvia X greggii ‘Cherry Chief’ (not patented). In comparison with ‘Cherry Chief’, whose mature height is between 60 and 90 cm, ‘Ignition Purple’ is more compact and low growing. In addition, the flowers of ‘Cherry Chief’ are less-saturated mid-red in color.
