USPP27971P2 - Hypericum plant named ‘Allboo’ - Google Patents

Abstract

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

Description

Botanical designation: Hypericum hybrida.

Cultivar denomination: ‘ALLBOO’.

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 a cut-flower plant and hereinafter referred to by the name ‘Allboo’.

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 strong stems, numerous attractive fruits and good postproduction longevity.

The new Hypericum plant originated from an open-pollination in September, 2011 in Cuijk, The Netherlands of a proprietary selection of Hypericum hybrida identified as code number C10-145, 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, 2012.

Asexual reproduction of the new Hypericum plant by vegetative cuttings in a controlled outdoor nursery environment in Cuijk, The Netherlands since September, 2012 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 ‘Allboo’. These characteristics in combination distinguish ‘Allboo’ as a new and distinct Hypericum plant:

• • 1. Broadly upright plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Dark green-colored leaves.
  • 4. Freely flowering habit and high fruit density.
  • 5. Glossy bright green-colored fruits.
  • 6. Suitable as a cut-flower plant.

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

• • 1. Leaves of plants of the new Hypericum have obtuse apices whereas leaves of plants of the female parent selection have acute apices.
  • 2. Plants of the new Hypericum produce larger fruits than plants of the female parent selection.
  • 3. Plants of the new Hypericum and the female parent selection differ in fruit color as plants of the female parent selection produce light yellow green-colored fruits.

Plants of the new Hypericum can be compared to plants of the Hypericum hybrida ‘Allbam’, not patented. In side-by-side comparisons, conducted in Cuijk, The Netherlands, plants of the new Hypericum differed primarily from plants of ‘Allbam’ in the following characteristics:

• • 1. Leaves of plants of the new Hypericum had obtuse apices whereas leaves of plants of ‘Allbam’ had acute apices.
  • 2. Plants of the new Hypericum and ‘Allbam’ differed in fruit color as plants of ‘Allbam’ produced light green-colored fruits.
