Abstract

A new and distinct cultivar of Weigela plant named ‘Bokrasopea’, characterized by its relatively compact, upright and somewhat outwardly spreading plant habit; freely branching habit; dark green-colored leaves; freely and repeat-flowering habit; white-colored flowers that are tinged with red purple and with red purple-colored throats; and good garden performance.

Description

Botanical designation: Weigela hybrida.

Cultivar denomination: ‘BOKRASOPEA’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Weigela plant, botanically known as Weigela hybrida and hereinafter referred to by the name ‘Bokrasopea’.

The new Weigela plant is a product of a planned breeding program conducted by the Inventor in Boskoop, The Netherlands. The objective of the breeding program was to develop new compact and repeat-flowering Weigela plants with attractive leaf and flower colors.

The new Weigela plant originated from an open-pollination during the summer of 2000 of a proprietary selection of Weigela hybrida identified as code number 93028, not patented, as the female, or seed, parent with an unknown selection of Weigela hybrida as the male, or pollen, parent. The new Weigela plant was discovered and selected by the Inventor in June, 2007 as a single flowering plant from within the progeny of the stated open-pollination in a controlled environment in Boskoop, The Netherlands.

Asexual reproduction of the new Weigela plant by softwood cuttings in Boskoop, The Netherlands since the summer of 2007 has shown that the unique features of this new Weigela plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Weigela have not been observed under all possible 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 ‘Bokrasopea’. These characteristics in combination distinguish ‘Bokrasopea’ as a new and distinct Weigela plant:

- 1. Relatively compact, upright and somewhat outwardly spreading plant habit.
- 2. Freely branching habit.
- 3. Dark green-colored leaves.
- 4. Freely and repeat-flowering habit.
- 5. White-colored flowers that are tinged with red purple and with red purple-colored throats.
- 6. Good garden performance.

In side-by-side comparisons conducted in Boskoop, The Netherlands, plants of the new Weigela differ primarily from plants of the female parent selection in the following characteristics:

- 1. Plants of the new Weigela are not as compact as plants of the female parent selection.
- 2. Plants of the new Weigela and the female parent selection differ in flower bud and flower color as plants of the female parent selection have pink-colored flower buds and flowers.

Plants of the new Weigela can be compared to plants of the Weigela florida ‘Bristol Snowflake’, not patented. In side-by-side comparisons in Boskoop, The Netherlands, plants of the new Weigela differed primarily from plants of ‘Bristol Snowflake’ in the following characteristics:

- 1. Plants of the new Weigela were more compact than plants of ‘Bristol Snowflake’.
- 2. Plants of the new Weigela and ‘Bristol Snowflake’ differed in flower bud and flower color as plants of ‘Bristol Snowflake’ had white-colored flower buds and flowers.
- 3. Plants of the new Weigela had a repeat-flowering habit whereas plants of ‘Bristol Snowflake’ did not have a repeat-flowering habit.

Plants of the new Weigela can also be compared to plants of the Weigela florida ‘Polka’, not patented. In side-by-side comparisons in Boskoop, The Netherlands, plants of the new Weigela differed primarily from plants of ‘Polka’ in the following characteristics:

- 1. Plants of the new Weigela and ‘Polka’ differed in flower color as plants of ‘Polka’ had pink-colored flowers.
- 2. Plants of the new Weigela had a repeat-flowering habit whereas plants of ‘Polka’ did not have a repeat-flowering habit.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Weigela 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 Weigela plant.

The photograph on the first sheet comprises a side perspective view of a typical vegetative plant of ‘Bokrasopea’ grown in a container.

The photograph on the second sheet is a close-up view of a typical flowering plant of ‘Bokrasopea’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs, following observations and measurements describe plants grown during the summer in one-gallon containers in an outdoor nursery in Grand Haven, Mich. and under commercial production practices. Plants were three years old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
