USPP36077P2 - Scabiosa plant named ‘Ichbu2005’ - Google Patents

Abstract

A new cultivar of Scabiosa plant named ‘Ichbu2005’ that is characterized by its inflorescences that are an intense and deep purple-blue color and its good tolerance to cold and heat.

Description

Botanical classification:

Scabiosa hybrid.

Variety denomination: ‘Ichbu2005’.

CROSS-REFERENCE TO A RELATED APPLICATION

This application claims priority to European Community Plant Variety Office (CPVO) Plant Breeder's Rights Application No. 2023/1514 filed on Jul. 17, 2023, under 35 U.S.C. 119(f), the entire contents of which is incorporated by reference herein.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Scabiosa of hybrid origin, botanically known as Scabiosa ‘Ichbu2005’ and will be referred to hereinafter by its cultivar name, ‘Ichbu2005’.

The new cultivar was derived from a controlled breeding program by the Inventor in Hachioji-shi, Tokyo, Japan. The Inventor made a cross in July of 2019 between an unnamed and unpatented proprietary plant in the Inventor's breeding program, reference name “Non-name-my Blue”, as the female parent that was pollinated with a mixture of pollen from the Inventor's breeding program. The male parent is therefore unknown. The Inventor selected ‘Ichbu2005’ as a single unique plant in May of 2020 from amongst the seedlings that resulted from the above cross.

Asexual propagation of the new cultivar was first accomplished by the Inventor by stem cuttings in October of 2019 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 ‘Ichbu2005’. These characteristics in combination distinguish ‘Ichbu2005’ as a new and distinct cultivar of Scabiosa.

• • 1. ‘Ichbu2005’ exhibits inflorescences that are an intense and deep purple-blue color.
  • 2. ‘Ichbu2005’ exhibits good tolerance to cold and heat.

The female parent of ‘Ichbu2005’ differs from ‘Ichbu2005’ in having a taller plant height, longer stems, and inflorescences that are lighter in color. ‘Ichbu2005’ can be most closely compared to the Scabiosa cultivars ‘Butterfly Blue’ (not patented) and ‘ICHPIN’ (U.S. Plant Pat. No. 28,303). ‘Butterfly Blue’ is similar to ‘Ichbu2005’ in having inflorescences that are purple-blue in color. ‘Butterfly Blue’ differs from ‘Ichbu2005’ in having a less neat and less tidy plant habit, inflorescences that are paler and less intense purple-blue in color, and a less tolerance to cold and heat. ‘ICHPIN’ differs from ‘Ichbu2005’ in having inflorescences that are bright pink in color.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR

The Applicant asserts that no publications or advertisements relating to sales, offers for sale, or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor. The Applicant claims a prior art exemption under 35 U.S.C. 102(b)(1) for disclosures and/or sales that fall within a one-year grace period to the filing date. Disclosures include website listings by Walter Blom Plants, Perfect Plants (ebay), and Hishtill (linkedin).
