| Abstract: |
A new and distinct cultivar of Hydrangea plant named `Bulk`, characterized by its upright and somewhat outwardly spreading plant habit; uniform and even growth habit; early and freely flowering habit; large upright flower panicles; and large panicles with white-colored sterile flowers that become red purple in color in the late summer and fall. |
| Claim: |
It is claimed:
1. A new and distinct cultivar of Hydrangea plant named `Bulk`, as illustrated and described. |
| Description: |
Botanical designation:Hydrangea paniculata.
Cultivar denomination: `Bulk`.
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 cultivar name Bulk.
The new Hydrangea is a chance seedling from an open-pollination of two unknown Hydrangea paniculata selections. The cultivar Bulk was discovered and selected by the Inventor as a single plant within the progeny of the stated open-pollination ina controlled environment in Boskoop, The Netherlands in 1991.
Asexual reproduction of the new cultivar by softwood cuttings in Boskoop, The Netherlands since the summer of 2002, has shown that the unique features of this new Hydrangea are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the cultivar Bulk 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 `Bulk`. These characteristics in combination distinguish `Bulk` as a new and distinct cultivar: 1. Upright and somewhat outwardlyspreading plant habit. 2. Uniform and even growth habit. 3. Early and freely flowering habit. 4. Large upright flower panicles. 5. Large panicles with white-colored sterile flowers that become red purple in color in the late summer and fall.
Plants of the new Hydrangea can be compared to plants of the Hydrangea cultivar Pink Diamond, not patented. In side-by-side comparisons conducted in Grand Haven, Mich., plants of the new Hydrangea differed from plants of the cultivar PinkDiamond in the following characteristics: 1. Plants of the new Hydrangea were smaller than plants of the cultivar Pink Diamond. 2. Plants of the new Hydrangea were much more freely branching than plants of the cultivar Pink Diamond. 3. Plants of thenew Hydrangea had longer leaves than plants of the cultivar Pink Diamond. 4. Plants of the new Hydrangea started flowering earlier than plants of the cultivar Pink Diamond. 5. Plants of the new Hydrangea had fewer sterile flowers per inflorescencethan plants of the cultivar Pink Diamond. 6. Plants of the new Hydrangea had longer lasting flowers sterile flowers than plants of the cultivar Pink Diamond. 7. Plants of the new Hydrangea and the cultivar Pink Diamond differed in flower colorationin the late summer and fall as flowers of plants of the new Hydrangea were darker in color than flowers of the cultivar Pink Diamond.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the unique appearance of the new cultivar, 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 thecolor values cited in the detailed botanical description which accurately describe the colors of the new Hydrangea.
The photograph on the first sheet is a side perspective view of a typical plant of the new Hydrangea in the summer.
The photograph at the bottom of the second sheet is a side perspective view of a typical plant of `Bulk` in August showing the red purple coloration that develops during the late summer and fall.
The photograph at the top of the second sheet comprises a close-up view of a typical inflorescence of `Bulk` showing the red purple coloration that develops during the late summer and fall.
DETAILED BOTANICAL DESCRIPTION
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. Plants used in the aforementioned photographs and inthe following description were grown in Grand Haven, Mich., in ground beds in an outdoor nursery and under conditions which closely approximate commercial production conditions.
