USPP36735P2 - Hydrangea plant named ‘Bokomabo’ - Google Patents

Abstract

A new cultivar of Hydrangea paniculata plant named ‘Bokomabo’ that is characterized by its moderately vigorous growth habit, its compact plant habit, its sturdy and healthy foliage, its sterile flower sepals that are white in color and change to dark red-purple to grey-purple after flowering, its ovate to conical shaped inflorescences, and its inflorescences that are not very dense and consist of both fertile and sterile flowers.

Description

Botanical classification: Hydrangea paniculata.

Varietal denomination: ‘Bokomabo’.

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, ‘Bokomabo’. ‘Bokomabo’ represents a new panicle Hydrangea, a perennial shrub grown for use as a landscape plant.

‘Bokomabo’ was derived from an ongoing breeding program conducted by the Inventor in Boskoop, The Netherlands. The goal of the breeding program is to develop new cultivars of Hydrangea paniculata with novel characteristics.

The new cultivar originated as a seedling that arose from seed planted from open pollination of an unnamed and unpatented plant of Hydrangea paniculata in July of 2012. The male parent is therefore unknown. ‘Bokomabo’ was selected as a single unique plant in July of 2020 from the resulting seedlings.

Asexual propagation of the new cultivar was first accomplished by softwood stem cuttings by the Inventor in Boskoop, The Netherlands in July of 2020. Asexual propagation by softwood stem cuttings 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 ‘Bokomabo’ as a unique cultivar of Hydrangea.

• • 1. ‘Bokomabo’ exhibits a moderately vigorous growth habit.
  • 2. ‘Bokomabo’ exhibits a compact plant habit.
  • 3. ‘Bokomabo’ exhibits sturdy and healthy foliage.
  • 4. ‘Bokomabo’ exhibits sterile flower sepals that are white in color and change to dark red-purple to grey-purple after flowering.
  • 5. ‘Bokomabo’ exhibits ovate to conical shaped inflorescences.
  • 6. ‘Bokomabo’ exhibits inflorescences that are not very dense and consist of both fertile and sterile flowers.

The female parent plant of ‘Bokomabo’ differs from ‘Bokomabo’ in having weaker, longer stems, a more vigorous growth habit, and sterile flower sepals that change to green and pink after opening. ‘Bokomabo’ can be most closely compared to the Hydrangea paniculata cultivars ‘Bokomaho’ (U.S. Plant Pat. No. 33,496) and ‘Bokomapishad’ (U.S. Plant Pat. No. 36,068). ‘Bokomaho’ is similar to ‘Bokomabo’ in having a compact plant habit and inflorescences with white sterile flower sepals. ‘Bokomaho’ differs from ‘Bokomabo’ in having a more compact plant habit, greater flowering as a one-year-old plant, and sterile flower sepals that change to yellow-green and slightly pink in color after flowering. ‘Bokomapishad’ is similar to ‘Bokomabo’ in having a compact plant shape and similar sterile flower sepal color after flowering. ‘Bokomapishad’ differs from ‘Bokomabo’ in having inflorescences that have more sterile flowers to cover the fertile flowers, a more vigorous and stronger growing habit that results in longer branches, and inflorescences that are larger in size.
