USPP32658P2 - Salvia plant named ‘GRUSALRP’ - Google Patents

Abstract

‘GRUSALRP’ is a new and distinctive Salvia plant which is characterized by a broad upright growth habit, a broad inverted triangular plant form, large dark green foliage, an abundance of dark violet flowers borne on long terminal inflorescences that sit above the foliage, and plants bearing a large number of inflorescences at once. The new variety propagates successfully by stem cuttings and has shown to be uniform and stable in the resulting generations from asexual propagation.

Description

Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Salvia x sylvestris.

Variety denomination: The inventive variety of Salvia disclosed herein has been given the variety denomination ‘GRUSALRP’.

BACKGROUND OF THE INVENTION

Parentage: ‘GRUSALRP’ is a naturally occurring, whole-plant mutation of Salvia x sylvestris ‘Rianne’ (Community Plant Variety Rights grant number 41746) which was discovered at a commercial nursery in Rockanje, the Netherlands in May of 2019. The mutation was noted for its abundance of tall inflorescence bearing an abundance of dark violet flowers. The mutation was isolated for further evaluation in order to confirm the distinctness and stability of the characteristics first observed. Upon confirmation of distinctness and stability, ‘GRUSALRP’ was selected for commercialization.

Asexual Reproduction: Asexual reproduction of ‘GRUSALRP’ was first accomplished in autumn of 2019 by rooting softwood stem cuttings at a commercial greenhouse in Rockanje, the Netherlands. Two successive generations have shown that the unique features of the instant cultivar are stable and reproduce true to type.

SUMMARY OF THE INVENTION

The cultivar ‘GRUSALRP’ has not been observed under all possible environmental conditions and the phenotype may vary somewhat with variations in the instant environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following traits have been repeatedly observed and represent the distinguishing characteristics of the new Salvia plant, ‘GRUSALRP’.

• • 1. Salvia ‘GRUSALRP’ exhibits a broad, upright growth habit with a broad, inverted triangular plant profile; and
  • 2. Salvia ‘GRUSALRP’ exhibits large, dark green foliage; and
  • 3. Salvia ‘GRUSALRP’ exhibits an abundance of relatively large, dark violet labiate flowers borne on long, terminal verticillaster inflorescences that sit above the foliage; and
  • 4. Salvia ‘GRUSALRP’ exhibits a floriferous flowering habit with plants bearing a large number of inflorescences at once.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed botanical description of a new and distinct variety of Salvia known as ‘GRUSALRP’, based upon observations of 3 month old plants in 11 cm nursery containers, grown outdoors in Rockanje, the Netherlands. Plants were grown using conventional field production protocols for Salvia plants which consisted of regular overhead irrigation. No pest or disease control measures were utilized in production. Temperatures ranged between 18 to 35 degrees Celsius during the day and 12 to 22 degrees Celsius at night. Plants were produced with full sun exposure and no photoperiodic treatments or artificial light was given to the plants. Observation data was recorded in September of 2019.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘GRUSALRP’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such measurements are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climactic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2015 edition.
