Abstract: A new and distinct cultivar of Heuchera plant named `Raspberry Chiffon`, characterized by its full, densely foliated and uniformly mounded plant habit; vigorous growth habit; ruffled purple bronze and silver-colored leaves; numerous large light pink-colored flowers arranged on erect panicles; and excellent garden performance.
Claim: It is claimed:

1. A new and distinct Heuchera plant named `Raspberry Chiffon` as illustrated and described.
Description: Botanical designation:Heuchera.times.hybrida.

Cultivar denomination: `Raspberry Chiffon`.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Heuchera, botanically known as Heuchera.times.hybrida and hereinafter referred to by the name `Raspberry Chiffon`.

The new Heuchera is a product of a planned breeding program conducted by the Inventor in Scottdale, Pa. The objective of the breeding program is to create new vigorous Heuchera cultivars with uniform plant habit, and attractive leaf and flowercoloration.

The new Heuchera originated from a cross-pollination made by the Inventor in May, 2000 in Scottdale, Pa. of Heuchera `Pearl Pendants`, not patented, as the female, or seed, parent with a proprietary selection of Heuchera identified as codenumber H99-9B, not patented, as the male, or pollen, parent. The new Heuchera was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Scottdale,Pa. in June, 2001.

Asexual reproduction of the new Heuchera by cuttings in a controlled greenhouse environment in Scottdale, Pa. since October, 2001, has shown that the unique features of this new Heuchera are stable and reproduced true to type in successivegenerations.

SUMMARY OF THE INVENTION

The new Heuchera has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature, daylength and light intensity without, however, anyvariance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Raspberry Chiffon`. These characteristics in combination distinguish `Raspberry Chiffon` as a new and distinct cultivar of Heuchera: 1. Full, densely foliated and uniformly mounded plant habit. 2. Vigorous growth habit. 3. Ruffled purple bronze and silver-colored leaves. 4. Numerous large light pink-colored flowers arranged on erect panicles. 5. Excellent garden performance.

Plants of the new Heuchera differ from plants of the female parent, `Pearl Pendants`, in the following characteristics: 1. Leaves of plants of the new Heuchera are more deeply lobed than leaves of plants of `Pearl Pendants`. 2. Leaves ofplants of the new Heuchera are more ruffled than leaves of plants of `Pearl Pendants`. 3. Plants of the new Heuchera and `Pearl Pendants` differ in leaf color as plants of `Pearl Pendants` have bronze green-colored leaves.

Plants of the new Heuchera differ from plants of the male parent selection in the following characteristics: 1. Leaves of plants of the new Heuchera are more deeply lobed than leaves of plants of the male parent selection. 2. Leaves of plantsof the new Heuchera are more ruffled than leaves of plants of the male parent selection. 3. Plants of the new Heuchera and the male parent selection differ in leaf color as plants of the male parent selection have grey green-colored leaves.

Plants of the new Heuchera can be compared to plants of the Heuchera `Harmonic Convergence`, disclosed in U.S. Plant Pat. No. 11,111. In side-by-side comparisons conducted in Scottdale, Pa., plants of the new Heuchera differed from plants of`Harmonic Convergence` in the following characteristics: 1. Leaves of plants of the new Heuchera were smaller, more deeply lobed and more ruffled than leaves of plants of `Harmonic Convergence`. 2. Plants of the new Heuchera had shorter and narrowerinflorescences than plants of `Harmonic Convergence`. 3. Plants of the new Heuchera had larger flowers than plants of `Harmonic Convergence`.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Heuchera, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightlyfrom the color values cited in the detailed botanical description which accurately describe the colors of the new Heuchera.

The photograph on the first sheet comprises a side perspective view of a typical plant of `Raspberry Chiffon`.

The photograph on the second sheet is a close-up view of typical flowers of `Raspberry Chiffon`.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in Scottdale, Pa. in one-gallon containers in a glass-covered greenhouse and under conditions which closely approximate commercial Heucheraproduction.

Plants were one year old when the photographs and the description weretaken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
