Abstract

A new and distinct cultivar of Sanguisorba plant named ‘Jam Session’, characterized by its compact plant habit with upright flowering stems; moderately vigorous growth habit; dark green-colored leaves; numerous white-colored flowers on dense inflorescences; and good garden performance.

Description

Botanical designation: Sanguisorba officinalis.

Cultivar denomination: ‘JAM SESSION’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sanguisorba plant, botanically known as Sanguisorba officinalis and hereinafter referred to by the name ‘Jam Session’.

The new Sanguisorba plant originated from an open-pollination during the summer of 2015 in Lisserbroek, The Netherlands, of Sanguisorba officinalis ‘Red Thunder’, not patented, as the female, or seed, parent with an unknown selection of Sanguisorba officinalis as the male, or pollen, parent. The new Sanguisorba plant was discovered and selected by the Inventors as a single plant from within the progeny of the stated open-pollination in a controlled environment in Lisserbroek, The Netherlands in August, 2016.

Asexual reproduction of the new Sanguisorba plant by divisions in a controlled environment in Lisserbroek, The Netherlands since February, 2017 has shown that the unique features of this new Sanguisorba plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Sanguisorba have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Jam Session’. These characteristics in combination distinguish ‘Jam Session’ as a new and distinct Sanguisorba plant:

    • 1. Compact plant habit with upright flowering stems.
    • 2. Moderately vigorous growth habit.
    • 3. Dark green-colored leaves.
    • 4. Numerous white-colored flowers on dense inflorescences.
    • 5. Good garden performance.

Plants of the new Sanguisorba differ primarily from plants of the female parent, ‘Red Thunder’, in plant habit as plants of the new Sanguisorba are more compact than and shorter than plants of ‘Red Thunder’. In addition, plants of the new Sanguisorba have white-colored flowers whereas plants of ‘Red Thunder’ have dark pinkish red-colored flowers.

Plants of the new Sanguisorba can be compared to plants of Sanguisorba officinalis ‘Tanna’, not patented. Plants of the new Sanguisorba differ primarily from plants of ‘Tanna’ in plant habit as plants of the new Sanguisorba are more taller than plants of ‘Tanna’. In addition, plants of the new Sanguisorba have white-colored flowers whereas plants of ‘Tanna’ have dark pinkish red-colored flowers.

Plants of the new Sanguisorba can also be compared to plants of Sanguisorba officinalis ‘Proud Mary’, not patented. Plants of the new Sanguisorba differ primarily from plants of ‘Proud Mary’ in leaf color as plants of the new Sanguisorba have dark green-colored leaves whereas plants of ‘Proud Mary’ have bluish green-colored leaves. In addition, plants of the new Sanguisorba have white-colored flowers whereas plants of ‘Proud Mary’ have pinkish red-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Sanguisorba plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Sanguisorba plant.

The photograph on the first sheet is a side perspective view of typical flowering plant of ‘Jam Session’ grown in a container.

The photograph on the second sheet is a close-up view of a typical inflorescence of ‘Jam Session’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the autumn in 25-cm containers in an outdoor nursery in Lisserbroek, The Netherlands and under cultural practices typical of commercial Sanguisorba production. During the production of the plants, day temperatures ranged from 12° C. to 25° C. and night temperatures ranged from 4° C. to 15° C. Plants were one year old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
