Abstract

A new and distinct cultivar of Hypericum plant named ‘Kolmiglow’, characterized by its upright and outwardly spreading plant habit; moderately vigorous growth habit; dark purple-colored developing stems; relatively small leaves that dark green in color with dark purple-colored lower surfaces; freely flowering habit; high fruit density; and glossy dark red-colored fruits.

Description

Botanical designation: Hypericum×inodorum.
Cultivar denomination: ‘KOLMIGLOW’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Hypericum plant, botanically known as Hypericum×inodorum and hereinafter referred to by the name ‘Kolmiglow’.
The new Hypericum plant is a product of a planned breeding program conducted by the Inventor in Heelsum, The Netherlands. The objective of the breeding program is to create new Hypericum plants with strong stems, dark-colored leaves, and numerous attractive fruits.
The new Hypericum plant originated from a cross-pollination conducted by the Inventor in 2009 in Heelsum, The Netherlands of a proprietary selection of Hypericum×inodorum identified as code number 8205-04, not patented, as the female, or seed parent with a proprietary selection of Hypericum×inodorum identified as code number 393-00, not patented, 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 cross-pollination in a controlled greenhouse environment in Heelsum, The Netherlands in 2010.
Asexual reproduction of the new Hypericum plant by vegetative cuttings in a controlled greenhouse environment in Boskoop, The Netherlands since 2011 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 ‘Kolmiglow’. These characteristics in combination distinguish ‘Kolmiglow’ as a new and distinct Hypericum plant:
    • 1. Upright and outwardly spreading plant habit.
    • 2. Moderately vigorous growth habit.
    • 3. Dark purple-colored developing stems.
    • 4. Relatively small leaves that dark green in color with dark purple-colored lower surfaces.
    • 5. Freely flowering habit; high fruit density.
    • 6. Glossy dark red-colored fruits.
Plants of the new Hypericum differ primarily from plants of the female parent selection in the following characteristics:
    • 1. Plants of the new Hypericum and the female parent selection differ in developing stem color as plants of the female parent selection have green-colored developing stems.
    • 2. Plants of the new Hypericum and the female parent selection differ in fruit color as plants of the female parent selection have dark brown-colored fruits.
Plants of the new Hypericum differ from plants of the male parent selection in the following characteristics:
    • 1. Plants of the new Hypericum and the male parent selection differ in developing stem color as plants of the male parent selection have green-colored developing stems.
    • 2. Plants of the new Hypericum and the male parent selection differ in fruit shape as plants of the male parent selection have elliptic-shaped fruits.
Plants of the new Hypericum can also be compared to plants of the Hypericum ‘Pinky Flair’, not patented. In side-by-side comparisons, conducted in Boskoop, The Netherlands, plants of the new Hypericum differed primarily from plants of ‘Pinky Flair’ in the following characteristics:
    • 1. Plants of the new Hypericum and ‘Pinky Flair’ differed in leaf lower surface color as plants of ‘Pinky Flair’ had leaves with green-colored lower surfaces.
    • 2. Plants of the new Hypericum and ‘Pinky Flair’ differed in flower bud color as plants of ‘Pinky Flair’ had yellow-colored flower buds.
    • 3. Plants of the new Hypericum and ‘Pinky Flair’ differed in fruit luster and color as plants of ‘Pinky Flair’ had matte (non-glossy) and light red-colored fruits.
Plants of the new Hypericum can be compared to plants of the Hypericum ‘Kolmred’, disclosed in U.S. Plant Pat. No. 13,554. In side-by-side comparisons, conducted in Boskoop, The Netherlands, plants of the new Hypericum differed primarily from plants of ‘Kolmred’ in the following characteristics:
    • 1. Plants of the new Hypericum and ‘Kolmred’ differed in leaf lower surface color as plants of ‘Kolmred’ had leaves with green-colored lower surfaces.
    • 2. Plants of the new Hypericum and ‘Kolmred’ differed in fruit shape plants of ‘Kolmred’ had elliptic-shaped fruits.
    • 3. Plants of the new Hypericum and ‘Kolmred’ differed in fruit luster as plants of ‘Kolmred’ had matte (non-glossy) fruits.
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 comprises a side perspective view of a typical flowering plant of ‘Kolmiglow’ grown in a container.
The photograph on the second sheet is a close-up view of a typical stems and leaves of ‘Kolmiglow’.
The photograph on the third sheet is a close-up view of a typical flower and developing flower buds of ‘Kolmiglow’.
The photograph on the fourth sheet is a close-up view of a typical fruit of ‘Kolmiglow’.
 DETAILED BOTANICAL DESCRIPTION
Plants used for the aforementioned photographs and following description were grown in 22-cm containers during the autumn in an outdoor nursery in Boskoop, The Netherlands and under cultural practices typical of commercial Hypericum production. During the production of the plants, day temperatures ranged from 12° C. to 25° C. and night temperatures ranged from 4° C. to 15° C.
