plant named ‘Pmoore02’

Abstract

A new cultivar of Scabiosa ‘Pmoore02’ that is characterized by its long flowering period, its short stature, its sterile flowers that do not produce seed, its inflorescences that are light green and turn pale pink to pale purple in color, its long lasting cut flowers, and its compact plant habit.

Description

Botanical classification: Scabiosa atropurpurea×Scabiosa caucasica.

Variety denomination: ‘Pmoore02’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Scabiosa plant, botanically a hybrid of interspecific origin known as Scabiosa ‘Pmoore02’ and will be referred to hereafter by its cultivar name, ‘Pmoore02’. The new cultivar represents a new herbaceous perennial grown for garden and landscape use.

The new invention arose from an ongoing controlled breeding program conducted by the Inventor in Longstock, England with the objective of developing new cultivars of Scabiosa with a non invasive plant habit that do not seed.

‘Pmoore02’ was derived from a cross made in 2009 between an unnamed and unpatented plant of Scabiosa atropurpurea plant as the female parent and an unnamed and unpatented plant of Scabiosa caucasica plant as the male parent. ‘Pmoore02’ was selected in 2010 as a single unique plant from amongst the resulting seedlings.

Asexual propagation of the new cultivar was first accomplished by the Inventor by stem cuttings in 2010 in Longstock, England. Asexual propagation by 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 ‘Pmoore02’ as a unique cultivar of Scabiosa.

• • 1. ‘Pmoore02’ exhibits a long flowering period.
  • 2. ‘Pmoore02’ exhibits sterile flowers and does not produce seeds.
  • 3. ‘Pmoore02’ exhibits inflorescences that are light green and turn pale pink to pale purple in color.
  • 4. ‘Pmoore02’ exhibits long lasting cut flowers.
  • 5. ‘Pmoore02’ exhibits a compact plant habit.

The female parent differs from ‘Pmoore02’ in having inflorescences that are claret red in color, in having leaves that are more deeply dissected, and in producing seed. The male parent differs from ‘Pmoore02’ in having a less compact plant habit and in having inflorescences that are larger in size and produce seed. The Inventor is unaware of any cultivars of Scabiosa atropurpurea×Scabiosa caucasica for comparison. ‘Pmoore02’ can be compared to the Scabiosa columbaria cultivar ‘Walminipink’ (U.S. Plant Pat. No. 13,442) as it is similar in being long blooming and in having a compact plant habit and pink flowers. ‘Walminipink’ differs from ‘Pmoore02’ in having inflorescences that are pink throughout development and in producing reproductive organs.
