Salvia plant named ‘RFD-S018’

Abstract

A new cultivar of Salvia plant named ‘RFD-S018’ that is distinguished by its rich, clear magenta rose color, dark purple-brown calyx and dense foliage. These traits set ‘RFD-S018’ apart from all other existing varieties of Salvia known to the inventor.

Description

Genus: Salvia.

Species: greggii.

Denomination: RFD-S018.

BACKGROUND OF THE INVENTION

The present invention relates to a new variety of S. greggii Gray, hereinafter referred to by the cultivar name ‘RFD-S018’. ‘RFD-S018’ originated as a chance seedling from a potted plant found in the inventor's collection in a cultivated area of Greensboro, N.C., in March 1995. It was taken from the pot of a S. greggii Gray variety and maintained for asexual propagation purposes. The inventor presumes that ‘RFD-S018’ is a seedling of the adjacent plant, S. greggii Gray.

The inventor has been studying, collecting, and disseminating Salvia species for twenty-seven years. During this period, he has traded Salvia species and cultivars with many botanical gardens and nurseries.

One of the inventor's goals has been to sort out confusion on the identities of various forms of Salvias being marketed. This has necessitated developing contacts with various herbaria and taxonomic experts to assist with the proper identification of Salvia forms. The developed information has been supplied at times to Salvia collectors and to nurseries and botanic gardens where visits have been made to check on the correct identification of various Salvias.

Collected results of the identification of Salvias, along with horticultural information like zone hardiness, size, and bloom period and flower color have been reported in his publication, the Salvia Placard Handbook. Recently, the World of Salvia web site was created and is being maintained for the purpose of reporting this information about Salvias to the public.

The inventor has bred and introduced many successful commercial introductions, including Salvia greggii Gray hybrids ‘Cherry Chief’ (unpatented), ‘Cherry Queen’ (unpatented), ‘Maraschino’ (unpatented), and ‘Raspberry Royale’ (unpatented).

‘RFD-S018’ is distinguished from other varieties of the species known to the inventor and was selected for these distinguishing characteristics: namely, that the flowers of RFD-S018 are rich, clear magenta rose in color, in combination with a dark purple brown calyx that accents the flower and dense foliage.

‘RFD-S018’ was first asexually propagated in 1995 at Greensboro, N.C., USA using vegetative cuttings. It has been found to remain fixed, stable and uniform through several generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the distinguishing characteristics of ‘RFD-S018’. In combination these traits set the new cultivar apart from all others existing varieties of Salvia known to the inventor. ‘RFD-S018’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environment, climatic, and cultural conditions, however, without any variance in genotype.

1. Salvia ‘RFD-S018’ exhibits a rich, clear magenta rose color.

2. Salvia ‘RFD-S018’ exhibits dark purple brown calyx.

3. Salvia ‘RFD-S018’ exhibits dense foliage.

BREIF DESCRIPTION OF THE DRAWINGS

The accompanying drawings illustrate the distinguishing traits of the new Salvia cultivar ‘RFD-S018’. The photographs were taken in summer 2002 of a one year-old plant, in an 8″ container that were grown a greenhouse in a cultivated area of Arroyo Grande, Calif., USA.

The drawing on sheet 1 illustrates the entire plant in summer with its dense foliage.

Sheet 2 is a close-up view of the flower. The drawings were made using conventional photographic techniques. Although colors may appear different from actual colors due to light reflectance, they are as accurate as possible by conventional photography.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the Salvia plant named ‘RFD-S018’. Data was collected in April 2001 from one year-old plants grown in one gallon containers in full sun at Greensboro, N.C., USA. Phenotypic differences may be observed with variation in environmental, climatic, and cultural conditions. The color determinations are in accordance with The 1986 Edition of The Royal Horticulture Society Colour Chart except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to other Salvia plants.
