plant named ‘ICHWHIT’

Abstract

A new cultivar of Scabiosa, ‘ICHWHIT’, that is characterized by its very long blooming period, blooming from May through November in the United Kingdom, Japan and The Netherlands and has shown continuous bloom (12 months and longer) in the Mediterranean climate of Israel, its plant height that reaches 80 cm in height in bloom (foliage height of 40 cm), its inflorescences held on long peduncles, its inflorescences that are very clear white in color with very pale pink coloration in centers as temperatures cool later in the season and its pink anthers that are pronounced and very visible as florets develop.

Description

Botanical classification: Scabiosa hybrid.

Variety denomination: ‘ICHWHIT’.

CROSS REFERENCE TO A RELATED APPLICATION

This application is a U.S. Plant Patent Application filed for a plant derived from the same breeding program that is entitled Scabiosa Plant Named ‘ICHPIN’ (U.S. Plant Pat. No. 28,303).

BACKGROUND OF THE INVENTION

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

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, Scabiosa japonica, Scabiosa incisa and many hybrids of different species of Scabiosa. A key 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 with a reference code of 14SCA-W1.

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 ‘ICHWHIT’. These characteristics in combination distinguish ‘ICHWHIT’ as a new and distinct cultivar of Scabiosa.

• 1. ‘ICHWHIT’ exhibits a very long blooming period, blooming from May through November in the United Kingdom, Japan and The Netherlands and has shown continuous bloom (12 months and longer) in the Mediterranean climate of Israel.
• 2. ‘ICHWHIT’ exhibits a plant height that reaches 80 cm in height in bloom (foliage height of 40 cm).
• 3. ‘ICHWHIT’ exhibits inflorescences held on long peduncles.
• 4. ‘ICHWHIT’ exhibits inflorescences that are very clear white in color with very pale pink coloration in centers as temperatures cool later in the season.
• 5. ‘ICHWHIT’ exhibits creamy white and pink anthers that are pronounced and very visible as florets develop.

‘ICHWHIT’ can be most closely compared to the Scabiosa cultivars, ‘ICHPIN’ and ‘Fama White’ (seed strain, not patented) ‘ICHPIN’ is similar to ‘ICHWHIT’ in having inflorescences that are held on long peduncles and in having a very long blooming period. ‘ICHPIN’ differs from ‘ICHWHIT’ in having a shorter plant height, inflorescences that are bright pink in color with white coloration in the centers as temperatures cool later in the season and less visible and less pronounced anthers as florets develop. ‘Fama White’ is similar to ‘ICHWHIT’ in having white flowers. ‘Fama White’ differs from ‘ICHWHIT’ in having silvery blue foliage and much larger flowers with outer florets that have more ruffled margins and anthers that are white in color.

BRIEF DESCRIPTION OF THE DRAWINGS

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

The photograph in FIG. 1 provides a side view of ‘ICHWHIT’ 12 months in age as grown in a 2-liter container in a glass greenhouse in Moshav Nehalim, Israel.

The photograph in FIG. 2 provides a close-up view of the inflorescences of ‘ICHWHIT’ on a plant 12 months in age as grown outdoors in a 1-liter container in Moshav Nehalim, Israel.

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.
