Abstract

A new and distinct cultivar of Betonica plant named ‘Summer Snowcone’, characterized by its relatively compact and broadly upright plant habit; moderately vigorous to vigorous growth habit; dark green-colored leaves; freely flowering habit; relatively long inflorescences with white-colored flowers; and good garden performance.

Description

Botanical designation: Betonica officinalis.

Cultivar denomination: ‘SUMMER SNOWCONE’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Betonica plant, botanically known as Betonica officinalis, previously classified as Stachys officinalis and Stachys betonica, and hereinafter referred to by the name ‘Summer Snowcone’.

The new Betonica plant is a product of a planned breeding program conducted by the Inventors in Lisserbroek, The Netherlands. The objective of the breeding program was to create new compact and freely-flowering Betonica plants with unique and attractive flower colors.

The new Betonica plant originated from an open-pollination in June, 2016 in Lisserbroek, The Netherlands, of Betonica officinalis ‘Alba’, not patented, as the female, or seed, parent with an unknown selection of Betonica officinalis as the male, or pollen, parent. The new Betonica 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 June, 2017.

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

SUMMARY OF THE INVENTION

Plants of the new Betonica 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 ‘Summer Snowcone’. These characteristics in combination distinguish ‘Summer Snowcone’ as a new and distinct Betonica plant:

- 1. Relatively compact and broadly upright plant habit.
- 2. Moderately vigorous to vigorous growth habit.
- 3. Dark green-colored leaves.
- 4. Freely flowering habit.
- 5. Relatively long inflorescences with white-colored flowers.
- 6. Good garden performance.

Plants of the new Betonica differ primarily from plants of the female parent, ‘Alba’, in plant habit as plants of the new Betonica are more compact than and shorter than plants of ‘Alba’. In addition, plants of the new Betonica are more freely flowering than plants of ‘Alba’.

Plants of the new Betonica can be compared to plants of Betonica officinalis ‘Ukkie’, not patented. Plants of the new Betonica and ‘Ukkie’ differ primarily in the following characteristics:

- 1. Plants of the new Betonica have stronger stems than plants of ‘Ukkie’.
- 2. Plants of the new Betonica have darker green-colored leaves than plants of ‘Ukkie’.
- 3. Plants of the new Betonica have longer inflorescences than plants of ‘Ukkie’.
- 4. Plants of the new Betonica have white-colored flowers whereas plants of ‘Ukkie’ have lilac purple-colored flowers.

Plants of the new Betonica can also be compared to plants of Betonica officinalis ‘Pink Cotton Candy’, disclosed in U.S. Plant Pat. No. 21,436. Plants of the new Betonica and ‘Pink Cotton Candy’ differ primarily in the following characteristics:

- 1. Plants of the new Betonica are more compact and shorter than plants of ‘Pink Cotton Candy’.
- 2. Leaves of plants of the new Betonica have darker green-colored leaves than plants of ‘Pink Cotton Candy’.
- 3. Plants of the new Betonica have white-colored flowers whereas plants of ‘Pink Cotton Candy’ have bi-colored light and bright pink-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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

The photograph on the first sheet (FIG. 1 ) is a side perspective view of typical flowering plant of ‘Summer Snowcone’ grown in a container.

The photograph on the second sheet (FIG. 2 ) is a close-up view of a typical inflorescence of ‘Summer Snowcone’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in 19-cm containers in an outdoor nursery in Lisserbroek, The Netherlands and under cultural practices typical of commercial Betonica production. During the production of the plants, day temperatures ranged from 18° C. to 30° C. and night temperatures ranged from 6° C. to 18° 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.
