plant named ‘ARGGR17011’

Abstract

A new cultivar of hybrid Salvia plant named ‘ARGGR17011’ that is characterized by its bushy upright plant habit, its leaves that are small in size, its flowers that are pink in color, its foliage that is pale green in color, and its clump-forming growth habit with short, spreading rhizomes.

Description

Botanical classification: Salvia guaranitica x Salvia orbignaei.

Variety denomination: ‘ARGGR17011’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Salvia plant, botanically of hybrid origin and known as Salvia ‘ARGGR17011’ and will be referred to hereinafter by its cultivar name, ‘ARGGR17011’. ‘ARGGR17011’ is an herbaceous perennial grown for landscape use and for use as a container plant.

The new invention arose from an ongoing controlled breeding program in Mar del Plata, Argentina. The goal of the breeding program was to develop a new cultivar of Salvia with a bushy upright plant habit, smaller leaves, pink flowers and pale green foliage.

The Inventor made a controlled cross in March of 2016 in Mar del Plata, Argentina between Salvia guaranitica ‘Amistad’ (U.S. Plant Pat. No. 23,578) as the female parent and an unnamed and unpatented plant of Salvia orbignaei as the male parent. ‘ARGGR17011’ was selected in March of 2017 as a single unique plant amongst the resulting seedlings.

Asexual propagation of the new cultivar was first accomplished by softwood stem cuttings in Mar del Plata, Argentina in March 2017 under the direction the Inventor. Asexual propagation by softwood stem cuttings has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘ARGGR17011’ as a unique cultivar of Salvia.

• • 1. ‘ARGGR17011’ exhibits a bushy upright plant habit.
  • 2. ‘ARGGR17011’ exhibits leaves that are small in size.
  • 3. ‘ARGGR17011’ exhibits flowers that are pink in color.
  • 4. ‘ARGGR17011’ exhibits foliage that is pale green in color.
  • 5. ‘ARGGR17011’ exhibits clump-forming growth habit with short, spreading rhizomes.

The female parent of ‘ARGGR17011’ differs from ‘ARGGR17011’ in having a taller and less compact plant habit, flowers that are blue to mauve in color, and foliage that is dark green in color. The male parent of ‘ARGGR17011’ differs from ‘ARGGR17011’ in having woody stems (not herbaceous), inflorescences with flowers that are less congested, and leaves that are more narrow. ‘ARGGR17011’ can be compared to the Salvia cultivars ‘Amante’ (U.S. Plant Pat. No. 31,104) and ‘Black and Bloom’ (U.S. Plant Pat. No. 27,183). ‘Amante’ differs from ‘ARGGR17011’ in having a non-spreading plant habit, calyxes that are almost black in color, and flowers that are fuchsia to red in color. ‘Black and Bloom’ differs from ‘ARGGR17011’ in having a non-spreading plant habit, calyxes that are almost black in color, and flowers that are blue in color.
