Abstract

A new and distinct Hydrangea cultivar named ‘MONPULSEL’ is disclosed, characterized by broad foliage which is noticeably thicker and more rigid than typical. Plants are strongly upright with compact growth. Branching is excellent, with strong branches produced, holding inflorescences at a more upright position. The new variety is a Hydrangea, normally produced as an ornamental plant for containers or gardens.

Description

Latin name of the genus and species: Hydrangea aspera.
Variety denomination: ‘MONPULSEL’.
BACKGROUND OF THE INVENTION
The new Hydrangea cultivar is a product of a breeding program under the direction of the inventor, Richard Wells, a at a commercial nursery in Dayton, Oreg. The new variety was selected among a planting of seedlings of Hydrangea aspera ‘Plum Passion’, unpatented.
Seed was bulk collect from unpatented Hydrangea aspera ‘Plum Passion’ plants. The new variety was selected among a planting of these seedlings in May 2013.
First asexual reproduction of the new cultivar ‘Monhinschf’ was performed by softwood vegetative cuttings at a commercial laboratory in Dayton, Oreg. in August of 2013. Four generations have been produced, and have shown that the unique features of this cultivar are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar ‘MONPULSEL’ 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 ‘MONPULSEL’ These characteristics in combination distinguish ‘MONPULSEL’ as a new and distinct Hydrangea cultivar:
    • 1. Excellent branching.
    • 2. Strongly upright and compact growth habit.
    • 3. Strong branches hold inflorescence more upright.
    • 4. Foliage which is noticeably thicker and more rigid.
    • 5. Broad foliage.
PARENT COMPARISON
Plants of the new cultivar ‘MONPULSEL’ are similar to plants of the parent, in most horticultural characteristics, however, plants of the new cultivar ‘MONPULSEL’ differ in the following:
    • 1. The new variety produces stronger branches, resulting in a sturdier plant that does not flop open.
    • 2. Plants of the new variety are more upright and compact.
    • 3. Foliage of the new variety is thicker and more rigid, as well as wider.
    • 4. Flowers of the new variety are held more upright, due to stronger branches.
The parent variety was self-crossed, there is only one parent.
COMMERCIAL COMPARISON
‘MONPULSEL’ can be compared to the patented commercial variety Hydrangea aspera ‘Hot Chocolate’, unpatented. These varieties are similar in most horticultural characteristics; however ‘MONPULSEL’ differs in the following:
    • 1. The comparator produces darker pink flowers than the new variety.
    • 2. Plants of the new variety are approximately ½ the height of plants of this comparator.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘MONPULSEL’grown in a field, in Dayton, Oreg. USA. Age of the plant photographed is approximately 3 years.
FIG. 2 illustrates typical foliage and inflorescence of the new variety.
FIG. 3 illustrates new growth of the new variety.
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.
