plant named ‘Bailpantwo’
A new cultivar of Hydrangea paniculata plant named ‘Bailpantwo’ that is characterized by its compact plant habit (reaching 1.2 to 1.5 m in height and spread), its mid to late blooming season in Minnesota, its panicles that open creamy white in color and age to a dark pinkish red in color, its dense branching, and its floriferous blooming habit.

Botanical classification: Hydrangea paniculata.
Varietal denomination: ‘Bailpantwo’.
BACKGROUND OF THE INVENTIONThe present invention relates to a new and distinct cultivar of Hydrangea paniculata and will be referred to hereafter by its cultivar name, ‘Bailpantwo’. ‘Bailpantwo’ represents a new panicle hydrangea, a perennial shrub grown for use as a landscape plant.
‘Bailpantwo’ was derived from an ongoing breeding program conducted by the Inventors in Watkinsville, Georgia. The goals of the breeding program are to develop new cultivars of Hydrangea paniculata with compact plant habits, floriferous blooming habits, and tolerance to heat in southern climates.
‘Bailpantwo’ originated as a seedling that arose from seed planted from open pollination of Hydrangea paniculata ‘PIIHP-I’ (U.S. Plant Pat. No. 23,387) in summer of 2012. The male parent is therefore unknown. ‘Bailpantwo’ was selected as a single unique plant in summer of 2013 from the resulting seedlings.
Asexual propagation of the new cultivar was first accomplished by softwood stem cuttings by one of the Inventors in Watkinsville, Georgia in summer of 2014. 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 INVENTIONThe following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Bailpantwo’ as a unique cultivar of Hydrangea.
- 1. ‘Bailpantwo’ exhibits a compact plant habit (reaching 1.2 to 1.5 m in height and spread).
- 2. ‘Bailpantwo’ exhibits mid to late blooming season in Minnesota.
- 3. ‘Bailpantwo’ exhibits panicles that open creamy white in color and age to a dark pinkish red in color.
- 4. ‘Bailpantwo’ exhibits dense branching.
- 5. ‘Bailpantwo’ exhibits a floriferous blooming habit.
The parent plant of ‘Bailpantwo’ differs from ‘Bailpantwo’ in having a later blooming period (2 to 3 weeks later in Minnesota), flowers that age to a light, blush pink color, and inflorescences with a greater density of sterile florets. ‘Bailpantwo’ can be most closely compared to the Hydrangea paniculata cultivars ‘Rensun’ (U.S. Plant Pat. No. 25,438) and ‘Rendia’ (U.S. Plant Pat. No. 24,667). ‘Rensun’ is similar to ‘Bailpantwo’ in having a compact and rounded plant habit and full panicles. ‘Rensun’ differs from ‘Bailpantwo’ in having inflorescences with white flowers that age to medium pink in color, an earlier blooming period (3 to 4 weeks earlier in Minnesota), and a plant habit that is less dense with weaker stems. ‘Rendia’ is similar to ‘Bailpantwo’ in having a compact plant habit and inflorescences that age to a dark pinkish red color. ‘Rendia’ differs from ‘Bailpantwo’ in having an earlier blooming habit (1 to 2 weeks earlier in Minneosta), a more open plant habit with weaker stems, and inflorescences with fewer sterile flowers.
STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTORThe Applicant asserts that no publications or advertisements relating to sales, offers for sale, or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor. The Applicant claims a prior art exemption under 35 U.S.C. 102(b)(1) for disclosures and/or sales that fall within a one-year grace period to the filing date. Disclosures include a website listing by Nature Hills, Home and Garden Fullfillment, Garden Centerpoint, and My WAHM Plan.
The accompanying color photograph illustrates the overall appearance and distinct characteristics of the new Hydrangea.
The photograph was taken of a two-year-old plant of ‘Bailpantwo’ as grown outdoors in a trial bed in Cottage Grove, Minnesota. The colors in the photograph are as close as possible with the photographic and printing technology utilized and the color values cited in the detailed botanical description accurately describe the colors of the new Hydrangea.
