plant named ‘RUDTI124’

Abstract

A new cultivar of Rudbeckia plant named ‘RUDTI124’ that is characterized by its short plant height, its well-branched plant habit, its very floriferous blooming habit, its long flowering period, and its ray florets that are grey-purple to brown on lower ⅔rd of the florets and yellow-orange on upper ⅓rd of the florets.

Description

Botanical classification: Rudbeckia hirta.

Variety denomination: ‘RUDTI124’.

CROSS-REFERENCE TO A RELATED APPLICATION

This application is related to a European plant breeders' rights application filed on Sep. 5, 2018, application No. 2018/2289. There have been no offers for sale anywhere in the world prior to the effective filing date of this Application and no accessibility to one of ordinary skill in the art could have been derived from the printed plant breeder's rights documents.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Rudbeckia hirta and will hereafter by referred to by its cultivar name, ‘RUDTI124’. The new cultivar is an herbaceous perennial grown for use as a landscape plant.

‘RUDTI124’ was derived from a breeding program in July of 2016 conducted by the Inventor at a nursery in Zuidwolde, The Netherlands. The objective of the breeding program was to select new cultivars of Rudbeckia with floriferous blooming habits and compact plant habits.

‘RUDTI124’ was selected in July of 2017 by the Inventor from amongst seedlings in a trial field that had been planted with seed derived from open pollination of numerous unpatented and unnamed proprietary plants from the Inventor's breeding program. The exact parentage is therefore unknown.

Asexual propagation of the new cultivar was first accomplished under the direction of the Inventor by tissue culture using meristematic tissue in Heerhugowaard, The Netherlands in January of 2018. Asexual propagation by tissue culture has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

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 disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date. Disclosure include but may not be limited to a website listing by AB-Cultivars (a company owned by the Inventor).

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘RUDTI124’ as a unique cultivar of Rudbeckia.

• • 1. ‘RUDTI124’ exhibits a short plant height.
  • 2. ‘RUDTI124’ exhibits a well-branched plant habit.
  • 3. ‘RUDTI124’ exhibits a very floriferous blooming habit.
  • 4. ‘RUDTI124’ exhibits a long flowering period.
  • 5. ‘RUDTI124’ exhibits inflorescences with ray florets that are grey-purple to brown on the lower ⅔rd of the florets and yellow-orange on the upper ⅓rd of the florets.

‘RUDTI124’ can be compared to the Rudbeckia cultivars SMILEYZ® ‘Chocolate’ (not patented), and SMILEYZ® ‘RUDHT37’ (U.S. Plant Pat. No. 30,657). SMILEYZ® ‘Chocolate ’ is similar to ‘RUDTI124’ in having strong stems. SMILEYZ® ‘Chocolate’ differs from ‘RUDTI124’ in having a taller plant height and ray florets that are dark grey-orange in color and not bicolored. ‘RUDHT37’ is similar to ‘RUDTI124’ in floriferous blooming habit. ‘RUDHT37’ differs from ‘RUDTI124’ in having a smaller disk diameter, in commencing bloom later blooming season, and in having ray florets colors that are clear grey-orange on the lower half and dark yellow-orange on the upper half.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Rudbeckia. The photographs were taken of a 4-month-old plant of ‘RUDTI124’ as grown outdoors in a 19-cm container in Zuidwolde, The Netherlands.

The photograph in FIG. 1 is a side view of ‘RUDTI124’ in bloom.

The photograph in FIG. 2 provides a close-up view of an inflorescence of ‘RUDTI124’.

The photograph in FIG. 3 provides a close-up view of the foliage of ‘RUDTI124’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the detailed botanical description accurately describe the colors of the new Rudbeckia.
