plant named ‘Allhykim’

Abstract

A new and distinct cultivar of Hypericum plant named ‘Allhykim’, characterized by its upright plant habit; vigorous growth habit; dark green-colored leaves; freely flowering habit and high fruit density; large glossy bright salmon pink-colored fruits; and suitability as a cut flower plant.

Description

Botanical designation: Hypericum hybrida.

Cultivar denomination: ‘ALLHYKIM’.

BACKGROUND OF THE INVENTION

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

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 glossy fruits.

The new Hypericum plant originated from an open-pollination in August, 2013 in Cuijk, The Netherlands of a proprietary selection of Hypericum hybrida identified as code number 2-2013-58, not patented, as the female, or seed parent with an unknown selection of Hypericum hybrida 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 September, 2013.

Asexual reproduction of the new Hypericum plant by vegetative cuttings in a controlled outdoor nursery environment in Cuijk, The Netherlands since September, 2013 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 ‘Allhykim’. These characteristics in combination distinguish ‘Allhykim’ as a new and distinct Hypericum plant:

• • 1. Upright plant habit.
  • 2. Vigorous growth habit.
  • 3. Dark green-colored leaves.
  • 4. Freely flowering habit and high fruit density.
  • 5. Large glossy bright salmon pink-colored fruits.
  • 6. Suitable as a cut flower plant.

Plants of the new Hypericum differ primarily from plants of the female parent selection in fruit color as plants of the new Hypericum have bright salmon pink-colored fruits whereas fruits of plants of the female parent selection are pink in color.

Plants of the new Hypericum can be compared to plants of the Hypericum hybrida ‘Allloco’, not patented. In side-by-side comparisons plants of the new Hypericum differ primarily from plants of ‘Allloco’ in the following characteristics:

• • 1. Plants of the new Hypericum and ‘Allloco’ differ in fruit color as plants of the new Hypericum have salmon pink-colored fruits whereas fruits of plants of ‘Allloco’ are light pink in color.
  • 2. Fruits of plants of the new Hypericum are not as glossy as fruits of plants of ‘Allloco’.
  • 3. Sepals of plants of the new Hypericum are larger than sepals of plants of ‘Allloco’.

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 is a side perspective view of a fruiting stem of ‘Allhykim’.

The photograph on the second sheet comprise close views of the lower surface of a typical leaf, the upper surface of a typical leaf, and lateral and terminal views of typical developing fruits with and without sepals of ‘Allhykim’.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following description were grown in September in a ground bed in an outdoor nursery in Cuijk, The Netherlands and under cultural practices typical of commercial Hypericum production. During the production of the plants, day temperatures ranged from 13° C. to 26° C. and night temperatures ranged from 6° C. to 16° C. Plants were one year old when the photographs and description were taken.
