Abstract

A new and distinct cultivar of Hydrangea plant named ‘Levana’, characterized by its upright plant habit; strong and sturdy stems that hold inflorescences upright; large lacecap-type inflorescences with large white-colored sterile flowers; and fragrant flowers are attractive to butterflies, particularly Araschnia levana.

Description

Botanical designation: Hydrangea paniculata.
Cultivar denomination: ‘LEVANA’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Hydrangea plant, botanically known as Hydrangea paniculata and hereinafter referred to by the name ‘Levana’.
The new Hydrangea plant is a product of a planned breeding program conducted by the Inventor in Brecht, Belgium. The objective of the breeding program was to develop new Hydrangea plants with strong stems, reliability and tolerant to pathogens and pests.
The new Hydrangea plant originated from an open-pollination in 1996 of Hydrangea paniculata ‘Barbara’, disclosed in U.S. Plant Pat. No. 13,606, as the female, or seed parent and an unknown selection of Hydrangea paniculata as the male, or pollen, parent. The new Hydrangea plant was discovered and selected by the Inventor in 2002 as a flowering plant within the progeny of the stated open-pollination in a controlled environment in Brecht, Belgium.
Asexual reproduction of the new cultivar by softwood cuttings in a controlled environment in Brecht, Belgium has shown that the unique features of this new Hydrangea plant are stable and reproduced true to type in successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
Plants of the new Hydrangea have 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 following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Levana’. These characteristics in combination distinguish ‘Levana’ as a new and distinct cultivar of Hydrangea plant:
    • 1. Upright plant habit.
    • 2. Strong and sturdy stems that hold inflorescences upright.
    • 3. Large lacecap-type inflorescences with large white-colored sterile flowers.
    • 4. Fragrant flowers are attractive to butterflies, particularly Araschnia levana.
Plants of the new Hydrangea differ from plants of the female parent, ‘Barbara’, in the following characteristics:
    • 1. Plants of the new Hydrangea have stronger stems than plants of ‘Barbara’.
    • 2. Plants of the new Hydrangea have larger and more uniform inflorescences than plants of ‘Barbara’.
    • 3. Sterile flowers of plants of the new Hydrangea have smaller sepals than sterile flowers of plants of ‘Barbara’.
Plants of the new Hydrangea can be compared to plants of Hydrangea paniculata ‘Le Vasterival’, disclosed in U.S. Plant Pat. No. 20,272. In side-by-side comparisons, plants of the new Hydrangea differ from plants of ‘Le Vasterival’ in the following characteristics:
    • 1. Plants of the new Hydrangea are more upright than plants of ‘Le Vasterival’.
    • 2. Plants of the new Hydrangea have stronger stems than plants of ‘Le Vasterival’.
    • 3. Plants of the new Hydrangea have larger inflorescences than plants of ‘Le Vasterival’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the unique appearance of the new Hydrangea 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 from the color values cited in the detailed botanical description which accurately describe the colors of the new Hydrangea plant.
The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Levana’ grown in a container.
The photograph at the top of the second sheet is a close-up view of a typical inflorescence of ‘Levana’.
The photograph at the bottom of the second sheet is a close-up view of typical leaves of ‘Levana’.
 DETAILED BOTANICAL DESCRIPTION
Plants used for the aforementioned photographs and the following description were grown during the autumn in an outdoor nursery in The Netherlands and under conditions which closely approximate commercial Hydrangea production conditions. During the production of the plants, day temperatures ranged from 13° C. to 25° C. and night temperatures ranged from 4° C. to 16° C. Plants of the new Hydrangea were 18 months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
