plant named ‘STOCRGEU’

Abstract

A new cultivar of hybrid Geum plant named ‘STOCRGEU’ that is characterized by its strong growing habit, its compact plant habit, its flowers that are large in size and facing upward, and its flowers that are bright red in color.

Description

Botanical classification: Geum hybrid.

Variety denomination: ‘STOCRGEU’.

CROSS-REFERENCE TO A RELATED APPLICATION

This application claims priority to European Community Plant Variety Office (CPVO) Plant Breeder's Rights Application No. 2022/1073 filed on Apr. 22, 2022, under 35 U.S.C. 119(f), the entire contents of which is incorporated by reference herein. The Applicant received the information for the Plant breeders' rights application directly from the Inventor.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Geum plant, botanically of hybrid origin and known as Geum ‘STOCRGEU’ and will be referred to hereinafter by its cultivar name, ‘STOCRGEU’. The new cultivar of Geum is an herbaceous perennial grown for landscape and container use.

The new cultivar arose from an ongoing breeding program conducted by the Inventor in Knutsford, Cheshire, The United Kingdom. The new cultivar arose from open pollination of both unnamed and unpatented seedlings from the Inventor's breeding program and cultivars of Geum rivale and Geum coccineum in June of 2017. The seeds were pooled after collection and therefore the exact parents are unknown, however the new cultivar is believed to be a hybrid of Geum rivale and Geum coccineum based on its characteristics. ‘STOCRGEU’ was selected as a single unique plant from the seedling that resulted from sowing the mixture of seeds in August of 2018.

Asexual propagation of the new cultivar was first accomplished by division in Cheshire, United Kingdom in August 2018 under the direction of the Inventor. Asexual propagation by division 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 the new cultivar. These attributes in combination distinguish ‘STOCRGEU’ as a unique cultivar of Geum.

• • 1. ‘STOCRGEU’ exhibits a strong growing habit.
  • 2. ‘STOCRGEU’ exhibits a compact plant habit.
  • 3. ‘STOCRGEU’ exhibits flowers that are large in size and facing upward.
  • 4. ‘STOCRGEU’ exhibits flowers that are bright red in color.

‘STOCRGEU’ can be most closely compared to Geum cultivars ‘Macgeu001’ (U.S. Plant Pat. No. 28,476) and ‘Tropical Tempest’ (not patented). ‘Macgeu001’ differs from ‘STOCRGEU’ in having flowers that are lighter red in color with apricot shadings, a taller plant height, and a more open and lax plant habit. ‘Tropical Tempest’ differs from ‘STOCRGEU’ in having a taller plant height and flowers that are red-orange 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 Visions Pictures, Plantipp, Posadzone, and Rijnbeek Perennials (facebook).

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the overall appearance and distinct characteristics of the new Geum. The photographs were taken of a 2-year-old plant of ‘STOCRGEU’ as grown outdoors in a 17-cm container in Boskoop, The Netherlands.

The photograph in FIG. 1 provides a view of the plant habit of ‘STOCRGEU’ in bloom.

The photograph in FIG. 2 provides a close-up view of a flower of ‘STOCRGEU’.

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

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 Geum.
