Abstract

A new cultivar of Paeonia plant named ‘HR 01’, characterized by its large fully double flowers that are pure white in color and highly fragrant.

Description

Botanical classification: Paeonia lactiflora.
Variety denomination: ‘HR 01’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Paeonia lactiflora that will be referred to hereafter by its cultivar name, ‘HR 01’. ‘HR 01’ is an herbaceous perennial suitable for landscape plantings.
The new variety of Paeonia, ‘HR 01’, arose from a controlled cross made by the Inventor in Roelofarendsveen, The Netherlands in May 1980. The cross was made between ‘Duchess De Nemour’ (not patented) as the female parent and ‘Sarah Bernhardt’ (not patented) as the male parent. ‘HR 01’ was selected as a single unique plant in May 1986.
The new cultivar has been asexually propagated by division by the Inventor in Roelofarendsveen, The Netherlands in 1987. Asexual propagation determined that the characteristics of this 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 Paeonia as observed for a period of three years in Yamhill, Oreg. and further evaluated at several other test sites in the U.S. These attributes in combination distinguish ‘HR 01’ as a unique cultivar of Paeonia.
    • 1. ‘HR 01’ exhibits large fully double flowers that are pure white in color.
    • 2. ‘HR 01’ exhibits flowers that are highly fragrant.
The new cultivar of Paeonia can be readily distinguished from its parents and other cultivars. The female parent, ‘Duchess De Nemour’, is similar to ‘HR 01’ in having fragrant double white flowers, but differs from ‘HR 01’ in having petioloids that are light yellow and turn to light green, and in having a more sprawling plant habit. The male parent, ‘Sarah Bernhardt’, is similar to ‘HR 01’ in having highly fragrant flowers, however ‘Sarah Bernhardt’ differs from ‘HR 01’ in having pink flowers. ‘HR 01’ can also be compared to the cultivars ‘Festiva Maxima’ and ‘Kelway's Glorious’ (both not patented). Both cultivars are similar to ‘HR 01’ in having large, fragrant white flowers, however ‘Festiva Maxima’ differs from ‘HR 01’ in having red flecks on the petaloids and ‘Kelway's Glorious’ differs from ‘HR 01’ in having red flecks on the petaloids and opening from rosy pink flower buds.
BRIEF DESCRIPTION OF THE DRAWING
The accompanying colored photographs illustrate the overall appearance and distinct characteristics of a two year-old plant of ‘HR 01’ as field grown in Roelofarendsveen, The Netherlands.
FIG. 1 provides a view of cut stems in a vase.
FIG. 2 provides a view of a close-up view of a fully open flower.
FIG. 3 provides a close-up view of the foliage.
The colors in the photographs are as close as possible with digital photography techniques available, the color values cited in the detailed botanical description accurately describe the colors of the new Paeonia.
DETAILED BOTANICAL DESCRIPTION
The following is a detailed description of the new cultivar as observed on two year-old plants of the new cultivar as field grown in Roelofarendsveen, The Netherlands.

The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
