USPP21204P2 - Hydrangea plant named ‘Lolly Pop’ - Google Patents

Abstract

A new cultivar of Hydrangea macrophylla named ‘Lolly Pop’ that is characterized by its free-flowering habit and suitability as a cut flower, its well-developed mop-head type inflorescences with sterile flowers that are pink in color, held on sturdy pedicels, and resistant to sun scorch, high winds and rain and its very strong stems with sturdy leaves.

Description

Genus/species: Hydrangea macrophylla.

Varietal denomination: ‘Lolly Pop’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hydrangea macrophylla and will be referred to hereafter by its cultivar name, ‘Lolly Pop’. ‘Lolly Pop’ represents a new Bigleaf Hydrangea, a deciduous shrub grown for landscape use and for use as for use as a cut flower.

‘Lolly Pop’ was derived from an ongoing controlled breeding program by the Inventor that focuses on developing new cultivars of bigleaf hydrangeas for cut flower use. ‘Lolly Pop’ originated from a cross conducted in the Inventor's nursery in June 1999 in Amstelveen, The Netherlands between Hydrangea macrophylla ‘Bodensee’ (not patented) as the female parent and Hydrangea macrophylla ‘Snowball’ (not patented) as the male parent. The new Hydrangea was selected as a unique single plant from the progeny of the cross in May 2003.

Asexual reproduction of the new cultivar was first accomplished by softwood stem cuttings in Amstelveen, The Netherlands in August 2003 by the Inventor. The characteristics of this cultivar have been determined to be 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 ‘Lolly Pop’ as a unique cultivar of Hydrangea macrophylla.

• • 1. ‘Lolly Pop’ exhibits a free-flowering habit.
  • 2. ‘Lolly Pop’ exhibits well-developed mop-head type inflorescences with sterile flowers that are pink in color.
  • 3. ‘Lolly Pop’ exhibits very strong stems with sturdy leaves.
  • 4. ‘Lolly Pop’ exhibits inflorescences that are sturdy with strong pedicels.
  • 5. ‘Lolly Pop’ exhibits inflorescences that resistant to sun scorch, high winds and rain.
  • 6. ‘Lolly Pop’ is suitable for use as a cut flower.
  • 7. ‘Lolly Pop’ is hardy at least U.S.D.A. Zones 4 to 9.

The closest comparison plants to the new cultivar of Hydrangea are the parent plants. ‘Bodensee’ differs from ‘Lolly Pop’ in having much weaker stems, larger sized leaves, larger sized inflorescences, and sterile flowers that are lighter pink in color and subject to developmental abortion. ‘Snowball’ differs from ‘Lolly Pop’ having weaker stems, larger sized leaves, larger sized inflorescences, and inflorescences that are white in color and susceptible to sun scorch.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs in the figures were taken of a two year-old plant of ‘Lolly Pop’ as grown under greenhouse conditions with ambient light in a 3.5-liter container in Amstelveen, The Netherlands.

The photograph in FIG. 1 illustrates a side view of a plant of ‘Lolly Pop’ with fully mature to fading blooms.

The photograph in FIG. 2 provides a close-up view of an inflorescence of ‘Lolly Pop’.

The photograph in FIG. 3 provides a close-up view of a leaf of ‘Lolly Pop’. The colors in the photographs are as close as possible with the digital photography and printing techniques utilized and the color codes in the detailed botanical description more accurately describe the new Hydrangea.
