Salvia plant named ‘Sunsarupin’

Abstract

A new and distinct cultivar of Salvia plant named ‘Sunsarupin’, characterized by its upright and relatively compact plant habit; freely basal branching habit; dense and bushy plant form; freely flowering habit; dark pink-colored flowers; and tolerance to high and low temperatures.

Description

Botanical classification/cultivar designation: Salvia jamensis cultivar Sunsarupin.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Salvia plant, botanically known as Salvia jamensis, and hereinafter referred to by the name ‘Sunsarupin’.

The new Salvia is a product of a planned breeding program conducted by the Inventors in Yokaichi-shi, Shiga, Japan. The objective of the breeding program was to create new compact Salvia cultivars with bushy growth habit and numerous flowers with attractive coloration.

The new Salvia originated from a cross-pollination made by the Inventors in April, 1998 of a proprietary Salvia selection identified as code number 97S34-2, not patented, as the female, or seed, parent with the Salvia jamensis cultivar La Luna, not patented, as the male, or pollen, parent. The new Salvia was discovered and selected by the Inventors as a single flowering plant within the progeny of the stated cross-pollination grown in a controlled environment in Yokaichi-shi, Shiga, Japan.

Asexual reproduction of the new cultivar by cuttings and divisions taken at Yokaichi-shi, Shiga, Japan, since September, 2000, has shown that the unique features of this new Salvia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Sunsarupin have not been observed under all possible environmental conditions. 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 ‘Sunsarupin’. These characteristics in combination distinguish ‘Sunsarupin’ as a new and distinct Salvia cultivar:

1. Upright and relatively compact plant habit.

2. Freely basal branching, dense and bushy plant form.

3. Freely flowering habit.

4. Dark pink-colored flowers.

5. Tolerant to high and low temperatures.

Plants of the new Salvia differ from plants of the parents primarily in flower color as plants of the female parent selection have red purple-colored flowers and plants of the male parent, the cultivar La Luna, have yellow green-colored flowers.

Plants of the new Salvia differ from plants of the Salvia cultivars Sunsaruki, U.S. Plant patent application Ser. No. 10/716,055, and Sunsaruoro, U.S. Plant patent application Ser. No. 10/716,056 primarily in flower color.

Plants of the new Salvia can be compared to plants of the Salvia cultivar Orchestra Red, not patented. In side-by-side comparisons conducted in Yokaichi-shi, Shiga, Japan, plants of the new Salvia differed from plants of the cultivar Orchestra Red in the following characteristics:

1. Plants of the new Salvia were more compact than plants of the cultivar Orchestra Red.

2. Plants of the new Salvia had shorter internodes and were bushier than plants of the cultivar Orchestra Red.

3. Plants of the new Salvia had shorter leaves than plants of the cultivar Orchestra Red.

4. Plants of the new Salvia had larger flowers than plants of the cultivar Orchestra Red.

5. Plants of the new Salvia had more flowers per lateral stem than plants of the cultivar Orchestra Red.

6. Plants of the new Salvia and the cultivar Orchestra Red differed in flower color as plants of the cultivar Orchestra Red has red-colored flowers.

7. Plants of the new Salvia were tolerant to lower temperatures than plants of the cultivar Orchestra Red.

DETAILED BOTANICAL DESCRIPTION

Plants shown in the aforementioned photographs and used in the following description were grown under conditions which closely approximate commercial production conditions from April to October, 2002 in a polyethylene-covered greenhouse in Yokaichi-shi, Shiga, Japan. During the production of the plants, day temperatures were about 25° C. and night temperatures were about 20° C. Plants in the photographs and used for the description were about six months old when the photographs and description were taken.

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
