Abstract: A new cultivar of Hydrangea macrophylla named `Cotton Candy Two` that is characterized by its remontant (re-blooming) habit, blooming from May until frost, its lacecap type inflorescences with single sterile flowers surrounding a mass of fertile flowers, its flowers that are dark pink in color in color when grown with a soil PH of 7 or above, its sterile flowers with sepals that have serrated to crenated margins with a fine white edge on most sepals, and its 95% cutting rooting rate.
Claim: It is claimed:

1. A new and distinct cultivar of Hydrangea plant named `Cotton Candy Two` substantially as herein illustrated and described.
Description: Botanical classification: Hydrangea macrophylla.

Varietal denomination: `Cotton Candy Two`.


This application is co-pending with a U.S. Plant Patent Application filed `Dancing Butterflies Improved` (U.S. Plant patent application Ser. No. 13/317,953).


The present invention relates to a new and distinct cultivar of Hydrangea macrophylla and will be referred to hereafter by its cultivar name, `Cotton Candy Two`. `Cotton Candy Two` represents a new lacecap type Hydrangea, a deciduous shrubgrown for landscape use and for use as a potted plant.

`Cotton Candy Two` originated as a seedling that arose from seed planted from open pollination of Hydrangea macrophylla `Frau Reiko` (U.S. Plant Pat. No. 9,500) in Davis, Calif. The male parent is unknown. The open pollination occurred inMay 2005 and the new Hydrangea was selected as a unique single plant in June 2008.

Asexual reproduction of the new cultivar was first accomplished by the Inventor using softwood stem cuttings in Davis, Calif. in June 2008. The characteristics of this cultivar have been determined to be stable and are reproduced true to typein successive generations.


The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish `Cotton Candy Two` as a unique cultivar of Hydrangea macrophylla. 1. `Cotton Candy Two`exhibits a remontant (re-blooming) habit, blooming from May until frost. 2. `Cotton Candy Two` exhibits lacecap type inflorescences with single sterile flowers surrounding a mass of fertile flowers. 3. `Cotton Candy Two` exhibits flowers that aredark pink in color in color when grown with a soil PH of 7 or above. 4. `Cotton Candy Two` exhibits sterile flowers with sepals that have serrated to crenated margins with a fine white edge on most sepals. 5. `Cotton Candy Two` exhibits a 95% cuttingrooting rate.

`Cotton Candy Two` differs from its female parent, `Frau Reiko` in having a remontant blooming habit, in having a more compact plant habit, in having a much greater rooting rate, and in having 30% more branching. `Cotton Candy Two` can be mostclosely compared to the cultivars `Cotton Candy` (not patented) and `Dancing Butterflies Improved`. `Cotton Candy` differs from `Cotton Candy Two` in having a higher rooting rate and in being more compact in habit. `Dancing Butterflies Improved`differs from `Cotton Candy Two` in having sterile flowers that are lighter pink in color and in having a wider white margin with entire margins on the sepals of the sterile flowers.


The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Hydrangea as grown in a greenhouse in Abbotsford, British Columbia. The photographs were taken of a one year-old plant of `CottonCandy Two` as grown in a 23-cm container with a soil pH of 7.

The photograph in FIG. 1 illustrates the foliage and compact form of `Cotton Candy Two` and the photograph in FIG. 2 provides a close-up view of the inflorescences of `Cotton Candy Two`. The colors in the photographs may differ slightly fromthe color values cited in the detailed botanical description, which accurately describe the colors of the new Hydrangea.


The following is a detailed description of one year-old plants of `Cotton Candy Two` as grown in a greenhouse in 23-cm containers in Abbotsford, British Columbia. The detailed flower color data was taken from plants growing both under acidicconditions and alkaline conditions when differences exist. Phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions. The color determination is in accordance with The 2001 R.H.S. Colour Chart of TheRoyal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
