Abstract

A new cultivar of Dicentra plant, ‘Fire Island’, characterized by its numerous flowers that are pink in color, its very early flowering season, its multiple and short branches, its very resistance to diseases and high growing temperatures, and its vigorous growth habit during propagation, and its lack of seed production.

Description

Botanical classification: Dicentra peregrina×Dicentra exima.
Variety denomination: ‘Fire Island’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar Dicentra peregrina×Dicentra exima plant, botanically known as Dicentra ‘Fire Island’ and will be referred to hereinafter by its cultivar name, ‘Fire Island’. The new cultivar of Dicentra is a hardy herbaceous perennial grown for landscape use.
The new Dicentra was developed through on ongoing breeding program by the Inventor in Hokkaido, Japan to develop new cultivars of Dicentra with good vigor and long flowering periods. ‘Fire Island’ arose a cross make in June 2002 between an unnamed plant of Dicentra peregrina from the Inventor's breeding program as the female parent and an unnamed plant of Dicentra exima from the Inventor's breeding program as the male parent. ‘Fire Island’ was selected in June 2004 as a single unique plant from the above cross.
Asexual reproduction of the new cultivar was first accomplished by the Inventor by means of stem cuttings in December 2005 in Hokkaido, Japan. Asexual reproduction by cuttings and in vitro propagation 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 over a period of eight years and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Fire Island’ as a new and unique cultivar of Dicentra.
    • 1. ‘Fire Island’ exhibits flowers that are pink in color.
    • 2. ‘Fire Island’ exhibits numerous flowers and flowers very early in the growth season.
    • 3. ‘Fire Island’ is well branched with short branches.
    • 4. ‘Fire Island’ is presumed sterile as no seed set has been observed.
    • 5. ‘Fire Island’ has shown good disease resistance.
    • 6. ‘Fire Island’ has shown good resistance to high temperatures.
    • 7. ‘Fire Island’ has a vigorous growth habit during propagation.
‘Fire Island’ can be most closely compared to the cultivars ‘Rekka’ (U.S. Plant Pat. No. 20,058), ‘Burning Hearts’ (U.S. Plant Pat. No. 20,797) and ‘Red Fountain’ (U.S. Plant Pat. No. 21,269). ‘Rekka’ differs from ‘Fire Island’ in having darker pink flowers, less branching with longer branches, in having greater fragrance, in being less disease resistant, and by producing seeds. ‘Burning Hearts’ differs from ‘Fire Island’ in having flowers that are redder in color, in having less flowers, in having less branching with slightly longer branches, in flowering later, in being less disease resistant, and in having a slower growth habit during propagation. ‘Red Fountain’ differs from ‘Fire Island’ in having flowers that are redder in color, in having less branching with slightly longer branches, and in being less disease resistant.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Dicentra. The photographs were taken of a one year-old plant as grown outdoors in a three-liter container in De hoef, The Netherlands.
The photograph in FIG. 1 provides an overall view of ‘Lemon Frost’ in bloom.
The photograph in FIG. 2 provides a close up view of the foliage of ‘Fire Island’.
The photograph in FIG. 3 provides a close up view of the flowers of ‘Fire Island’. The colors in the photograph may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Dicentra.
DETAILED BOTANICAL DESCRIPTION
The following is a detailed description of 1 year-old plants of the new cultivar as grown outdoors in July in De Hoef, The Netherlands. The plants were grown under average day temperatures ranging from 15° C. to 32° C. and average night temperatures ranging from 8° C. to 18° C. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. 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.
