Abstract
A new cultivar of Hydrangea macrophylla plant named ‘Perla59361’ that is characterized by its compact plant habit, its terminal and axillary inflorescences, its inflorescences with sterile sepals that are deep red-pink in color with white margins, its early flowering, and its high resilience in warm and sunny growing conditions.
Description
Botanical classification: Hydrangea macrophylla.
Varietal denomination: ‘Perla59361’.
The present invention relates to a new and distinct cultivar of Hydrangea macrophylla and will be referred to hereafter by its cultivar name, ‘Perla59361’. ‘Perla59361’ represents a new mophead type Hydrangea, a deciduous shrub grown for use as a landscape plant.
‘Perla59361’ was derived from an ongoing breeding program conducted by the Inventor in Zevenhuizen, The Netherlands. A goal of the breeding program was to develop new cultivars of Hydrangea macrophylla that flower on first year wood and are resilient in warm and sunny climates.
The Inventor made a controlled cross in June of 2015 in Zevenhuizen, The Netherlands between unnamed and unpatented proprietary plants from their breeding program; female parent (ref code 13-01) and male parent (ref code 15-26-57-01). ‘Perla59361’ was selected in June of 2018 as a single unique plant amongst the resulting seedlings.
Asexual propagation of the new cultivar was first accomplished under the direction of the Inventors by stem cuttings in May of 2019 in Zevenhuizen, The Netherlands. Asexual propagation by stem cuttings has determined that the characteristics of the new cultivar are 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. These attributes in combination distinguish ‘Perla59361’ as a unique cultivar of Hydrangea.
-
- 1. ‘Perla59361’ exhibits a compact plant habit.
- 2. ‘Perla59361’ exhibits terminal and axillary inflorescences.
- 3. ‘Perla59361’ exhibits inflorescences with sterile sepals that are deep red-pink in color with white margins.
- 4. ‘Perla59361’ exhibits flowering early in the growing season.
- 5. ‘Perla59361’ exhibits high resilience to warm and sunny growing conditions.
The female parent of ‘Perla59361’ differs from ‘Perla59361’ in having sterile flower sepals that are all pink in color, fewer lateral branches, longer lateral branches, and a later blooming period. The male parent of ‘Perla59361’ differs from ‘Perla59361’ in having sterile flower sepals that are light pink in color with broader white margins, more lateral branches, and a much lower tolerance to warm and sunny climates. ‘Perla59361’ can be most closely compared to the Hydrangea macrophylla cultivars ‘Saxcanhea’ (not patented) and ‘Bavaria’ (not patented). Both ‘Saxcanhea’ and ‘Bavaria’ are similar to ‘Perla59361’ in having bi-color flowers. ‘Saxcanhea’ and ‘Bavaria’ both differ from ‘Perla59361’ in having different color sterile flower sepals. ‘Saxcanhea’ is light pink in color with broader white margins and ‘Bavaria’ is lavender blue with broader white margins. Both have more lateral branches and lower tolerance to warm and sunny growing conditions.
The accompanying color photographs illustrates the overall appearance and distinct characteristics of the new Hydrangea. The photographs were taken of a 4-year-old plant as grown in a greenhouse in a 15-cm container in Zevenhuizen, The Netherlands.
The photograph in FIG. 1 provides a side view of the plant habit of ‘Perla59361’ in bloom.
The photograph in FIG. 2 provides a close-up view of an inflorescence of ‘Perla59361’.
The photograph in FIG. 3 provides a close-up view of a leaf of ‘Perla59361’.
The colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Hydrangea.
The following is a detailed description of 4-year-old plants of ‘Perla59361’ as grown in a greenhouse in 15-cm containers in Zevenhuizen, The Netherlands. The plants were grown under non-blueing conditions and blueing conditions have not been used. The color determination is in accordance with The 2015 Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
