plant named ‘Queen of Sheba’

Abstract

A new and distinct cultivar of Cimicifuga plant named ‘Queen of Sheba’, characterized by its upright and sturdy plant habit; dark-colored leaves; freely flowering habit; white-colored flowers arranged on pendulous racemes; and good garden performance.

Description

Botanical designation: Cimicifuga simplex×Cimicifuga racemosa.

Cultivar denomination: ‘QUEEN OF SHEBA’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Cimicifuga plant, botanically known as Cimicifuga simplex×Cimicifuga racemosa and hereinafter referred to by the name ‘Queen of Sheba’.

The new Cimicifuga plant is a product of a planned breeding program conducted by the Inventor in Hummelo, The Netherlands. The objective of the breeding program was to create new Cimicifuga plants with darker-colored leaves and more pendulous racemes.

The new Cimicifuga plant originated from a cross-pollination made by the Inventor during the summer of 2007 in Hummelo, The Netherlands, of the Cimicifuga simplex ‘James Compton’, not patented, as the female, or seed, parent with the Cimicifuga racemosa ‘Changchang’, not patented, as the male, or pollen, parent. The new Cimicifuga plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Hummelo, The Netherlands in the summer of 2008

Asexual reproduction of the new Cimicifuga plant by divisions in a controlled environment in Hummelo, The Netherlands since 2008, has shown that the unique features of this new Cimicifuga plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Cimicifuga have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices 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 ‘Queen of Sheba’. These characteristics in combination distinguish ‘Queen of Sheba’ as a new and distinct cultivar of Cimicifuga:

• • 1. Upright and sturdy plant habit.
  • 2. Dark-colored leaves.
  • 3. Freely flowering habit.
  • 4. White-colored flowers arranged on pendulous racemes.
  • 5. Good garden performance.

Plants of the new Cimicifuga differ from plants of the female parent, ‘James Compton’ primarily in leaf coloration as plants of ‘James Compton’ have much lighter-colored leaves.

Plants of the new Cimicifuga differ from plants of the male parent, ‘Changchang’ primarily in inflorescence orientation as plants of ‘Changchang’ have less pendulous to upright racemes.

Plants of the new Cimicifuga can be compared to plants of Cimicifuga simplex ‘Brunette’, not patented. Plants of the new Cimicifuga and ‘Brunette’ differ primarily in inflorescence orientation as plants of ‘Brunette’ have upright racemes.
