Abstract
A new cultivar of Hydrangea paniculata named ‘RENSUN’, characterized by its panicles of flowers of primarily sterile flowers that emerge white in mid summer and change to pink as they mature with the combination of white and pink panicles providing a multicolor effect, its reddish-brown flowering stems, and its uniform and compact plant habit with good suitability for planting in small spaces and containers.
Description
Genus/species: Hydrangea paniculata.
Varietal denomination: ‘RENSUN’.
The present invention relates to a new and distinct cultivar of Hydrangea paniculata and will be referred to hereafter by its cultivar name, ‘RENSUN’. ‘RENSUN’ represents a new deciduous shrub grown for landscape use.
The new Hydrangea resulted from a controlled breeding program that commenced in 1987 in Gorron, France. ‘RENSUN’ was selected as a whole plant mutation in a seedling plot in the ground in Gorron, France in 2005. The parents of ‘RENSUN’ were unnamed proprietary seedlings that arose after a multiple series of crosses.
Asexual reproduction of the new cultivar was first accomplished by softwood cuttings in May of 2006 by the Inventor in Gorron, France. The characteristics of this cultivar have been determined to be stable and are reproduced true to type in successive generations.
The following traits have been repeatedly observed and represent the characteristics of the new cultivar as observed on plant grown in Gorron, France. These attributes in combination distinguish in ‘RENSUN’ from other varieties of Hydrangea known to the Inventor.
-
- 1. ‘RENSUN’ blooms with panicles of flowers that emerge white in mid summer and change to pink as they mature, the combination of white and pink panicles provide a multicolor effect.
- 2. ‘RENSUN’ exhibits a uniform and compact plant habit with good suitability for planting in small spaces and containers.
- 3. ‘RENSUN’ exhibits reddish-brown flowering stems.
- 4. ‘RENSUN’ exhibits primarily sterile flowers as fertile flowers are rarely produced.
Comparison to other Hydrangea paniculata cultivars:
‘Unique’ (not patented) is similar to ‘RENSUN’ in having white flowers that turn pink but differs from ‘RENSUN’ in having more fertile flowers, and in having a more erect and less compact plant habit. ‘DVPpinky’ (U.S. Plant Pat. No. 16,166) is similar to ‘RENSUN’ in having flowers that are white in color and turn pink, however ‘DVPpinky’ differs from ‘RENSUN’ having a more erect plant habit and in having flowers that the pink coloration exists for a very short time before turning red, and also in having more fertile flowers. ‘RENHY’ (U.S. Plant Pat. No. 20,670) is similar to ‘RENSUN’ in having white flowers that turn to pink and in lacking fertile flowers, however ‘RENHY’ differs from ‘RENSUN’ in having flowers that subsequently change to red or burgundy and in having a less compact plant habit.
The drawings presented are digital photographs taken of plants 3 years in age in Gorron, France.
The photograph in FIG. 1 provides a view of the plant habit of ‘RENSUN’ in bloom as grown in a 2-gallon container.
The photograph in FIG. 2 provides a close-up view of inflorescences of ‘RENSUN’.
The photograph in FIG. 3 provides a close-up view of a plant of ‘RENSUN’ grown in a garden.
The colors in the photographs are as close as possible with the photographic and printing technology utilized. The color values cited in the detailed botanical description accurately describe the colors of the new Hydrangea.
The following is a detailed description of the new cultivar as observed on 3 year-old plants as grown outdoors in Gorron, France and of plants two years in age as grown under greenhouse conditions in St. Paul, Minn. Phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions. The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
