Abstract

A new cultivar of Hydrangea paniculata named ‘Hpopr013’, that is characterized by its conical shaped inflorescences with pointed apices, its gray-purple stems, its sterile flowers that open yellow-green and fade to pink, and its upright plant habit.

Description

Genus/species: Hydrangea paniculata.

Varietal denomination: ‘Hpopr013’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hydrangea paniculata and will be referred to hereafter by its cultivar name, ‘Hpopr013’. ‘Hpopr013’ represents a new lacecap type Hydrangea, a deciduous shrub grown for landscape use and for use as a potted plant.

The new cultivar of Hydrangea, ‘Hpopr013, was discovered by the Inventor as a chance seedling in a trial garden in Rijkevorsel, Belgium in June 2010. The exact parentage is unknown, however ‘Dharuma’ (not patented) and ‘Pink Diamond’ (not patented) are thought to be probable parents based on the characteristics of the new cultivar and their proximity to the new cultivar.

Asexual propagation of the new cultivar was first accomplished by the Inventor by softwood cuttings in June of 2010 in Rijkevorsel, Belgium. Asexual propagation by softwood cuttings and tissue culture has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish in ‘Hpopr013’ as a unique cultivar of Hydrangea.

- 1. ‘Hpopr013’ exhibits conical shaped inflorescences with pointed apices.
- 2. ‘Hpopr013’ exhibits gray-purple stems.
- 3. ‘Hpopr013’ exhibits sterile flowers that open yellow-green and fade to pink.
- 4. ‘Hpopr013’ exhibits an upright plant habit.
  ‘Dharuma’, a probable parent of ‘Hpopr013’, differs from ‘Hpopr013’ in having cylindrical inflorescences with an obtuse top and in having a less upright growing habit. ‘Pink Diamond, a probable parent of ‘Hpopr013’, differs from ‘Hpopr013’ in having broader and less pointed inflorescences and white sterile flowers that fade to soft pink. ‘Hpopr013’ can be most closely be compared to Hydrangea paniculata cultivars ‘Limelight’ (U.S. Plant Pat. No. 12,874) and ‘DVPpinky’ (U.S. Plant Patent No. 16,166). ‘Limelight’ is similar to ‘Hpopr013’ in having yellow-green mature sterile flowers. ‘Limelight’ differs from ‘Hpopr013’ in having broader inflorescences with obtuse apices, in having sterile flowers that fade to a lighter pink color, and in having fewer fertile flowers. ‘DVPpinky’ is similar to ‘Hpopr013’ in having conical shaped inflorescences. ‘DVPpinky’ differs from ‘Hpopr013’ in having sterile flowers that fade to a dark pinkish red to purple-red color and in having fewer fertile flowers.

BRIEF DESCRIPTION OF THE DRAWINGS
