Abstract

A new and distinct cultivar of Hypericum plant named ‘Verocla’, characterized by its upright plant habit; durable dark green-colored leaves; bright light green-colored fruits; and good postproduction longevity.

Description

Botanical designation: Hypericum androsaemum.

Cultivar denomination: ‘Verocla’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Hypericum plant, botanically known as Hypericum androsaemum, commercially used as cut stems with fruits, and hereinafter referred to by the name ‘Verocla’.

The new Hypericum is a product of a planned breeding program conducted by the Inventor in Wieringerwerf, The Netherlands. The objective of the breeding program was to develop cut Hypericum varieties with attractive fruit coloration.

The new cultivar originated from a cross-pollination made by the Inventor in January, 2000 of a proprietary selection of Hypericum identified as code number A20345, not patented, as the female, or seed, parent with a proprietary selection of Hypericum identified as code number 121346, not patented, as the male, or pollen, parent. The cultivar Verocla was discovered and selected by the Inventor during the summer of 2001 as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Wieringerwerf, The Netherlands.

Asexual reproduction of the new Hypericum by terminal cuttings at Wieringerwerf, The Netherlands since September, 2001, has shown that the unique features of this new Hypericum are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Verocla’. These characteristics in combination distinguish ‘Verocla’ as a new and distinct cultivar:

- 1. Upright plant habit.
- 2. Durable dark green-colored leaves.
- 3. Bright light green-colored fruits.
- 4. Good postproduction longevity.

Plants of the new Hypericum differ from plants of the female parent selection in the following characteristics:

- 1. Plants of the new Hypericum have longer flowering stems than plants of the female parent selection.
- 2. Plants of the new Hypericum have smaller fruits than plants of the female parent selection.
- 3. Plants of new Hypericum and the female parent selection differ in fruit coloration as plants of the female parent selection have 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 have longer flowering stems than plants of the male parent selection.
- 2. Plants of the new Hypericum have more durable leaves than plants of the male parent selection.
- 3. Plants of the new Hypericum have fewer flowers per inflorescence than plants of the male parent selection.
- 4. Plants of the new Hypericum and the male parent selection differ in fruit coloration as plants of the male parent selection have red-colored fruits.

Plants of the new Hypericum can be compared to plants of the Hypericum cultivar Excellent Flair, not patented. In side-by-side comparisons conducted in Wieringerwerf, The Netherlands, plants of the new Hypericum differed from plants of the cultivar Excellent Flair in the following characteristics:

- 1. Plants of the new Hypericum had shorter, darker green and more durable leaves than plants of the cultivar Excellent Flair.
- 2. Plants of the new Hypericum had smaller flowers than plants of the cultivar Excellent Flair.
- 3. Plants of the new Hypericum had thicker and stronger flowering stems than plants of the cultivar Excellent Flair.
- 4. Fruits of plants of the new Hypericum were bright light green in color whereas fruits of plants of the cultivar Excellent Flair were brownish red in color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Hypericum, 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 Hypericum.

The photograph on the first sheet comprises a side perspective view of a typical flowering stem of ‘Verocla’ with developed fruit.

The photograph at the top of the second sheet is a close-up view of typical fruits of ‘Verocla’.

The photograph at the bottom of the second sheet is a close-up view of typical flowers of ‘Verocla’.

DETAILED BOTANICAL DESCRIPTION

The new Hypericum has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The aforementioned photographs, following observations and measurements describe plants grown in Tabacundo, Ecuador, in an outdoor nursery and under commercial production practices. Plants used for the photographs and the description were about one year old. The photographs and description were taken in March with day temperatures averaging 17° C., night temperatures averaging 10° C. and light levels ranging from 800 to 1,100 watts per square meter. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
