Abstract

A new cultivar of hybrid Heuchera named ‘Red Sea’, characterized by its leaves that are red in color with wavy margins and a glossy surface, and its early flowering season that continues throughout the summer.

Description

Botanical classification: Heuchera hybrid.
Cultivar designation: ‘Red Sea’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Heuchera, botanically of hybrid origin and known as a Heuchera ‘Red Sea’ and is hereinafter referred to by its cultivar name ‘Red Sea’.
The new cultivar was discovered as a chance seedling by the Inventor in summer of 2008 in a field plot of Heuchera in Pellenberg, Belgium. The parents of the new cultivar are unknown, however Heuchera ‘Blackout’ (U.S. Plant Pat. No. 20,613) and an unnamed and unpatented plant of Heuchera villosa with reddish foliage are thought to be possible parents based on their proximity to the discovered seedling and the characteristics of the new cultivar.
Asexual propagation of the new cultivar was first accomplished by tissue culture using meristem tissue under the direction of the Inventor in Beervelde, Belgium in September of 2008. Asexual propagation of the new cultivar by tissue culture has shown that the unique features are stable and 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 cultivar. These attributes in combination distinguish ‘Red Sea’ as a new and unique cultivar of Heuchera.
    • 1. ‘Red Sea’ exhibits leaves with wavy margins.
    • 2. ‘Red Sea’ exhibits leaves that are red in color with a glossy surface.
    • 3. ‘Red Sea’ exhibits an early flowering season that continues throughout the summer.
‘Red Sea’ can be most closely compared to its probable parents. The unnamed plant of Heuchera villosa differs from ‘Red Sea’ in having leaves that are less red in color, leaf surfaces that are matte, ruffled leaf margins and a flower season that is shorter and commences later. ‘Blackout’ differs from ‘Red Sea’ in having leaves that are blackish in color, a less vigorous growth habit, less orbicular shaped leaves and inflorescences that are less narrow and less straight in aspect. ‘Red Sea’ can be compared to the Heuchera cultivars ‘Mahogany’ (U.S. Plant Pat. No. 19,072) and ‘Fire Chief’ (U.S. Plant Pat. No. 21,880). Both are similar to ‘Red Sea’ in leaf shape and leaf color. ‘Mahogany’ differs from ‘Red Sea’ in having a shorter plant height, leaf margins that are less wavy, petioles that are less pubescent and inflorescences that are wider and less dense. ‘Fire Chief’ differs from ‘Red Sea’ in having a shorter plant height, a less vigorous growth habit, and inflorescences that are shorter with less flowers that are larger in size.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Heuchera. The photographs were taken of a plant 3 years in age as grown in an unheated greenhouse in a 7.5 liter container in Pellenberg, Belgium.
The photograph in FIG. 1 provides a side view of the plant habit and foliage coloration of ‘Red Sea’ in bloom.
The photograph in FIG. 2 provides a close-up view of an inflorescence of ‘Red Sea’.
The photograph in FIG. 3 provides a close-up view of a leaf of ‘Red Sea’.
The colors in the photographs are as close as possible with the digital photography techniques available, the color values cited in the detailed botanical description accurately describe the colors of the new Heuchera.
DETAILED BOTANICAL DESCRIPTION OF THE PLANT
The following is a detailed description of 3-year-old plants of the new cultivar as grown in an un-heated greenhouse in 7.5 liter containers in Pellenberg, Belgium. 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.
