Description

Botanical designation: Hydrangea macrophylla.

Cultivar denomination: ‘Shugert’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hydrangea plant, botanically known as Hydrangea macrophylla and hereinafter referred to by the name ‘Shugert’.

The new Hydrangea plant is a product of a planned breeding program conducted by the Inventor in Grand Haven, Mich. The objective of the breeding program was to develop new Hydrangeas with attractive foliage and flower coloration.

The new Hydrangea plant originated from an open-pollination during the summer of 2003 of the Hydrangea macrophylla ‘Bailmer’, disclosed in U.S. Plant Pat. No. 15,298, as the female, or seed parent and an unknown selection of Hydrangea macrophylla. The new Hydrangea plant was discovered and selected by the Inventor in May, 2005 as a flowering plant within the progeny of the stated open- pollination in a controlled outdoor nursery environment in Grand Haven, Mich.

Asexual reproduction of the new cultivar by softwood cuttings in Grand Haven, Mich. since June, 2005 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 and cultural practices 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 ‘Shugert’. These characteristics in combination distinguish ‘Shugert’ as a new and distinct cultivar of Hydrangea:

    • 1. Upright and mounded plant habit.
    • 2. Strong roots and stems.
    • 3. Strong and dark green-colored leaves.
    • 4. Early flowering habit.
    • 5. Large lacecap-type inflorescences with light purple-colored flowers.
    • 6. Ability to reflower and to develop flowers on new growth without a cold treatment.

Plants of the new Hydrangea differ primarily from plants of the female parent, ‘Bailmer’, in the following characteristics:

    • 1. Plants of the new Hydrangea have larger sterile flowers than plants of ‘Bailmer’.
    • 2. Plants of the new Hydrangea are hardier than plants of ‘Bailmer’.

Plants of the new Hydrangea can be compared to plants of ‘Fasan’, not patented. Plants of the new Hydrangea differ primarily from plants of ‘Fasan’ in the following characteristics:

    • 1. Plants of the new Hydrangea will develop flowers on new wood and will reflower whereas plants of ‘Fasan’ only develop flowers on old wood and do not reflower.
    • 2. Plants of the new Hydrangea have smaller inflorescences than plants of ‘Fasan’.
    • 3. Plants of the new Hydrangea are hardier than plants of ‘Fasan’.

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 ‘Shugert’ grown in an outdoor nursery.

The photograph on the second sheet is a close-up view of a typical inflorescence of ‘Shugert’.

 DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photographs and in the following description were grown during the summer in Grand Haven, Mich. in ground beds in an outdoor nursery and under conditions which closely approximate commercial production conditions. Plants of the new Hydrangea were three years old when the photographs and description were taken. 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.
