CROSS REFERENCE TO A RELATED APPLICATION

This application claims priority to European Community Plant Variety Office (CPVO) Plant Breeder's Rights Application No. 2023/2312 filed on Nov. 7, 2023, under 35 U.S.C. 119(f), the entire contents of which is incorporated by reference herein. The information for the Plant Breeders' Right Application was obtained directly from the Inventor.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sanguisorba officinalis and will be referred to hereafter by its cultivar name, ‘Strawberry Dream’. ‘Strawberry Dream’ represents a new burnet, an herbaceous perennial grown for landscape use.

The Inventor discovered the new cultivar in August of 2013 as a naturally occurring branch mutation of Sanguisorba ‘Rising Star’ (not patented) that was growing in a production field of ‘Rising Star’ in Rijnsburg, The Netherlands.

Asexual propagation of the new cultivar was first accomplished by division in December of 2015 by the Inventor in Rijnsburg, The Netherlands. Asexual propagation by division has determined that the new cultivar is stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

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

• • 1. ‘Strawberry Dream’ exhibits a late flowering season.
  • 2. ‘Strawberry Dream’ exhibits inflorescences and stems that are similar in height.
  • 3. ‘Strawberry Dream’ exhibits a compact plant habit.

The parent plant of ‘Strawberry Dream’ differs from ‘Strawberry Dream’ in having a much taller plant height. ‘Strawberry Dream’ can be most closely compared to Sanguisorba officinalis cultivars ‘Red Dream’ (U.S. Plant Pat. No. 32,441) and ‘Arnhem’ (not patented). Both ‘Red Dream’ and ‘Arnheim’ are both similar to ‘Strawberry Dream’ in plant habit and flower color. ‘Red Dream’ differs from ‘Strawberry Dream’ in having an earlier flower period and a taller plant height. ‘Arnheim’ differs from ‘Strawberry Dream’ in having an earlier flowering period, a taller plant height, and a more densely branched habit.

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 Holex Flower, OZ Export, Triangle Dream, Heyl, and Floral Market.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrates the overall appearance and distinct characteristics of the new Sanguisorba. The photographs were taken of a one-year-old plant of the new cultivar as field grown outdoors in Rijnsburg, The Netherlands and placed in a 30-cm container for the photographs.

The photograph in FIG. 1 illustrates the overall plant habit and appearance of ‘Strawberry Dream’ in bloom.

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

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

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

DETAILED BOTANICAL DESCRIPTION
