plant named ‘ICHPIN’

Abstract

A new cultivar of Scabiosa, ‘ICHPIN’, that is characterized by its very long blooming period, May through November in the United Kingdom and Netherlands and has shown continuous bloom 12 months and longer in Mediterranean climates of California, its plant height that reaches 90 cm in height in bloom (foliage height of 50 cm), its and its inflorescences that are held on long peduncles and very bright pink in color with white coloration in centers as temperatures cool later in the season.

Description

Botanical classification: Scabiosa hybrid.

Variety denomination: ‘ICHPIN’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Scabiosa of hybrid origin, botanically known as Scabiosa ‘ICHPIN’ and will be referred to hereinafter by its cultivar name, ‘ICHPIN’.

The new invention arose from an ongoing controlled breeding program conducted by the Inventor in Tokyo Japan working with collections of the species Scabiosa columbaria and Scabiosa japonica, and many hybrids of different species of Scabiosa. An objective of this program was to obtain new cultivars of Scabiosa that are healthy with good vigor, very long blooming, have desirable plant heights combined with unique flower colors.

The new cultivar arose from crosses made over a number of years between unnamed and unpatented plants from the Inventor's breeding program and seeds were pooled from the crosses and sown. The exact parentage is unknown. The new cultivar was selected in 2008 as a single unique plant from the above crosses.

Asexual propagation of the new cultivar was first accomplished by the Inventor by stem cuttings in 2008 in Tokyo, Japan. 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 are determined to be the characteristics of ‘ICHPIN’. These characteristics in combination distinguish ‘ICHPIN’ as a new and distinct cultivar of Scabiosa.

• • 1. ‘ICHPIN’ exhibits a very long blooming period, blooming from May through November in the United Kingdom and Netherlands and has shown continuous bloom 12 months and longer in Mediterranean climates of California.
  • 2. ‘ICHPIN’ exhibits a plant height that reaches 90 cm in height in bloom (foliage height of 50 cm).
  • 3. ‘ICHPIN’ exhibits inflorescences held on long peduncles.
  • 4. ‘ICHPIN’ exhibits inflorescences that are very bright pink in color with white coloration in centers as temperatures cool later in the season.

‘ICHPIN’ can be most closely compared to the Scabiosa columbaria cultivars, ‘Pink Mist’ (U.S. Plant Pat. No. 8,957) and ‘Butterfly Blue’ (not patented). ‘Pink Mist’ differs from ‘ICHPIN’ in having a much shorter plant habit, shorter peduncles, and having inflorescences that are light pink in color. ‘Butterfly Blue’ differs from ‘ICHPIN’ in in having a much shorter plant habit, shorter peduncles, and having inflorescences that are lilac blue in color.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrates the overall appearance and distinct characteristics of plants of the new Scabiosa.

The photograph in FIG. 1 provides a side view of ‘ICHPIN’ 18 months in age as grown in a 5-liter container in a glass greenhouse in Watsonsville, Calif.

The photograph in FIG. 2 provides a close-up view of the inflorescences of ‘ICHPIN’ on a plant 18 months in age as grown outdoors in a 5-liter container in Maldon, Essex, United Kingdom.

The photograph in FIG. 3 provides a side view of ‘ICHPIN’ 24 months in age as grown in a private garden in Maldon, Essex, United Kingdom.

The colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describes the colors of the new Scabiosa.
