Abstract

A new and distinct cultivar of Heuchera plant named ‘Inheuredfu’, characterized by its compact and uniformly mounded plant habit; vigorous growth habit; densely foliated and bushy appearance; ruffled dark burgundy-colored leaves that become dark brown with development; and excellent garden performance.

Description

Botanical designation: Heuchera×hybrida.

Cultivar denomination: ‘INHEUREDFU’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Heuchera plant of Heuchera, botanically known as Heuchera×hybrida and hereinafter referred to by the name ‘Inheuredfu’.

The new Heuchera plant originated from an open-pollination during July, 2007 in Heidesheim, Germany of Heuchera×hybrida ‘Peach Flambe’, disclosed in U.S. Plant Pat. No. 17,195, as the female, or seed, parent with an unknown selection of Heuchera×hybrida as the male, or pollen, parent. The new Heuchera plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated open-pollination in a controlled greenhouse environment in Heidesheim, Germany in April, 2008.

Asexual reproduction of the new Heuchera plant by stem cuttings in a controlled greenhouse environment in Heidesheim, Germany since May, 2008 has shown that the unique features of this new Heuchera plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

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

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Inheuredfu’. These characteristics in combination distinguish ‘Inheuredfu’ as a new and distinct Heuchera plant:

• • 1. Compact and uniformly mounded plant habit.
  • 2. Vigorous growth habit.
  • 3. Densely foliated and bushy appearance.
  • 4. Ruffled dark burgundy-colored leaves that become dark brown with development.
  • 5. Excellent garden performance.

Plants of the new Heuchera differ from plants of the female parent, ‘Peach Flambe’, in the following characteristics:

• • 1. Plants of the new Heuchera are more compact than plants of ‘Peach Flambe’.
  • 2. Leaves of plants of the new Heuchera are more ruffled than leaves of plants of ‘Peach Flambe’.
  • 3. Leaves of plants of the new Heuchera are darker and brighter in color than leaves of plants of ‘Peach Flambe’.

Plants of the new Heuchera can be compared to plants of the Heuchera ‘Peach Melba’, disclosed in U.S. Plant Pat. No. 17,131. In side-by-side comparisons conducted in Heidesheim, Germany, plants of the new Heuchera differed primarily from plants of ‘Peach Melba’ in the following characteristics:

• • 1. Leaves of plants of the new Heuchera were more ruffled than leaves of plants of ‘Peach Melba’.
  • 2. Plants of the new Heuchera and ‘Peach Melba’ differed in leaf lamina and venation color.

Plants of the new Heuchera can be compared to plants of the Heuchera ‘Caramel’, disclosed in U.S. Plant Pat. No. 16,560. In side-by-side comparisons conducted in Heidesheim, Germany, plants of the new Heuchera differed primarily from plants of ‘Caramel’ in the following characteristics:

• • 1. Leaves of plants of the new Heuchera were smaller and more ruffled than leaves of plants of ‘Caramel’.
  • 2. Leaves of plants of the new Heuchera were not as pubescent as leaves of plants of ‘Caramel’.
  • 3. Plants of the new Heuchera and ‘Caramel’ differed in leaf lamina and venation color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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

The photograph at the bottom of the sheet comprises a side perspective view of a typical plant of ‘Inheuredfu’ grown in a container.

The photograph at the top of the sheet is a close-up view of a typical plant of ‘Inheuredfu’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the autumn in one-gallon containers in an outdoor nursery in Bonsall, Calif. under cultural practices typical of commercial Heuchera production. During the production of the plants, day temperatures ranged from 27° C. to 32° C., night temperatures ranged from 20° C. to 24° C. and light levels ranged from 6,000 to 8,000 foot-candles. Plants were four months old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
