Abstract

A new and distinct cultivar of Hypericum plant named ‘ALLHYBELL’, characterized by its broadly upright plant habit; moderately vigorous growth habit; moderately strong to strong stems; dark green-colored leaves; freely flowering habit and high fruit density; spherical and glossy greenish yellow-colored fruits; and suitability as a cut flower plant.

Description

Botanical designation: Hypericum androseamum L.

Cultivar denomination: ‘ALLHYBELL’.

CROSS-REFERENCE TO CLOSELY-RELATED APPLICATIONS

A European Community Plant Breeder's Rights application for the instant plant was filed by the Assignee, Allplants Holding B.V. of Cuijk, The Netherlands on Apr. 3, 2024, application number 2024/0792. Foreign priority is not claimed to this application.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hypericum plant, botanically known as Hypericum androseamum L., typically grown as cut flowers and hereinafter referred to by the name ‘ALLHYBELL’.

The new Hypericum plant is a product of a planned breeding program conducted by the Inventor in Cuijk, The Netherlands. The objective of the breeding program is to create new Hypericum plants with numerous attractive fruits.

The new Hypericum plant originated from an open-pollination in September 2015 in Cuijk, The Netherlands of a proprietary selection of Hypericum androseamum L. identified as code number 2-2012-23-1, not patented, as the female, or seed parent with an unknown proprietary selection of Hypericum androseamum L. as the male, or pollen, parent. The new Hypericum plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination in a controlled outdoor nursery environment in Cuijk, The Netherlands in August 2016.

Asexual reproduction of the new Hypericum plant by vegetative cuttings in a controlled outdoor nursery environment in Cuijk, The Netherlands since August 2016 has shown that the unique features of this new Hypericum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Hypericum 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 ‘ALLHYBELL’. These characteristics in combination distinguish ‘ALLHYBELL’ as a new and distinct Hypericum plant:

- 1. Broadly upright plant habit.
- 2. Moderately vigorous growth habit.
- 3. Moderately strong to strong stems.
- 4. Dark green-colored leaves.
- 5. Freely flowering habit and high fruit density.
- 6. Spherical and glossy greenish yellow-colored fruits.
- 7. Suitable as a cut flower plant.

Plants of the new Hypericum differ primarily from plants of the female parent selection in fruit texture and shape as plants of the new Hypericum produce glossy spherical fruits whereas fruits of plants of the female parent selection are dull in luster and elliptical in shape.

Plants of the new Hypericum can be compared to plants of the Hypericum hybrida ‘Allhy1236’, disclosed in U.S. Plant Pat. No. 28,134. In side-by-side comparisons plants of the new Hypericum differ primarily from plants of ‘Allhy1236’ in the following characteristics:

- 1. Plants of the new Hypericum produce fewer fruits per plant than plants of ‘Allhy1236’.
- 2. Plants of the new Hypericum produce greenish yellow- colored fruits whereas fruits of plants of ‘Allhy1236’ are white in color.
- 3. Fruits of plants of the new Hypericum are more rounded in shape than fruits of plants of ‘Allhy1236’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Hypericum 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 actual colors of the new Hypericum plant.

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

The photograph on the second sheet (FIG. 2 ) is a close-up view of a typical flowering plant of ‘ALLHYBELL’ with developing fruits.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following description were grown during the autumn in 25-cm containers and in ground beds in an outdoor nursery in Cuijk, The Netherlands and under cultural practices typical of commercial cut flower Hypericum production. During the production of the plants, day temperatures ranged from 23° C. to 28° C. and night temperatures ranged from 7° C. to 12° C. Plants were pinched one time and were six months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Sixth Edition, except where general terms of ordinary dictionary significance are used.
