Abstract
A new and distinct Hydrangea plant named ‘ILVOCLOU’ is disclosed, characterized by compact plants producing lace-cap inflorescences having light violet-blue sterile flowers with purple sepals and medium violet-blue fertile flowers. Plants produce attractive foliage and bloom abundantly. The new variety is a Hydrangea, normally produced as an ornamental plant.
Description
Latin name of the genus and species: Hydrangea macrophylla.
Variety denomination: ‘ILVOCLOU’.
The new Hydrangea cultivar is a product of a planned breeding program conducted by the inventors, at a commercial nursery in Melle, Belgium. The objective of the breeding program was to produce new Hydrangea varieties with compact habits and strong blooming beginning in the first year. The cross resulting in this new variety was made during Summer of 2003.
The seed parent is the unpatented variety Hydrangea serrata ‘Bluebird’. The pollen parent is the unpatented variety Hydrangea macrophylla ‘Mariesii Perfecta’. The new variety was identified as a potentially interesting selection in the Summer of 2007, at a commercial greenhouse in Melle, Belgium.
Asexual reproduction of the new cultivar ‘ILVOCLOU’ by vegetative soft wood cuttings was first performed during the Summer of 2016, at a commercial greenhouse in Melle, Belgium. Subsequent propagation has shown that the unique features of this cultivar are stable and reproduced true to type in 6 successive generations.
The cultivar ‘ILVOCLOU’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘ILVOCLOU’ These characteristics in combination distinguish ‘ILVOCLOU’ as a new and distinct Hydrangea cultivar:
-
- 1. Compact plants.
- 2. Lace-cap inflorescence.
- 3. Sterile flowers colored light violet blue-with purple sepals.
- 4. Fertile flower colors colored medium violet-blue.
- 5. Abundant flowering.
- 6. Attractive foliage.
Plants of the new cultivar ‘ILVOCLOU’ are similar to plants of the seed parent variety Hydrangea serrata ‘Bluebird’ in most horticultural characteristics, however, plants of the new cultivar ‘ILVOCLOU’ differ in the following;
-
- 1. The new variety has more showy sepals than the seed parent.
- 2. The new variety is a more compact plant than the seed parent.
Plants of the new cultivar ‘ILVOCLOU’ are similar to plants of the pollen parent variety Hydrangea macrophylla ‘Mariesii Perfecta’ in most horticultural characteristics, however, plants of the new cultivar ‘ILVOCLOU’ differ in the following;
-
- 1. The new variety has lighter green foliage than the pollen parent variety.
- 2. The new variety has more showy sepals than the pollen parent.
- 3. The new variety has a stronger flower color than the pollen parent.
Plants of the new cultivar ‘ILVOCLOU’ can be compared to the variety Hydrangea macrophylla ‘SMHMLDD’, U.S. Plant Pat. No. 25,105. These varieties are similar in most horticultural characteristics; however ‘ILVOCLOU’ differs in the following:
-
- 1. The new variety has lighter green foliage than this comparator.
- 2. The new variety is more floriferous than this comparator.
- 3. The new variety is a more compact plant than this comparator.
The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘ILVOCLOU’.
The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
