Abstract
A new cultivar of Heuchera named ‘Maple Leaf’ that is characterized by its glossy young leaves, its flowers that are white in color and its unique foliage that is orange in color.
Description
Botanical classification: Heuchera hybrid.
Cultivar designation: ‘Maple Leaf’.
This application is related to U.S. Plant Patents for plants derived from the same breeding program that are entitled Heuchera Plant Named ‘Vulcano’ (U.S. Plant Pat. No. 25,625) and ‘Apricot’ (U.S. Plant Pat. No. 27,139).
The Applicant asserts that no publications or advertisements relating to sales, offers for sale, or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor. The Applicant claims a prior art exemption under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.
The present invention relates to a new and distinct cultivar of Heuchera of hybrid origin, botanically known as a Heuchera and is hereinafter referred to by its cultivar name ‘Maple Leaf’.
The new cultivar was discovered as a chance seedling in a trial field by the Inventor in Hantay, France in April of 2016. The trial field contained hundreds of proprietary Heuchera seedlings from the Inventor's breeding program and other cultivars. The exact parentage of ‘Maple Leaf’ is therefore unknown.
Asexual propagation of the new cultivar was first accomplished under the direction of the Inventor by tissue culture initiated from meristem tissue in Rijswijk, The Netherlands in April 2017. Asexual propagation of the new cultivar by tissue culture has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.
The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Maple Leaf’ as a new and unique cultivar of Heuchera.
-
- 1. ‘Maple Leaf’ exhibits glossy young leaves.
- 2. ‘Maple Leaf’ exhibits flowers that are white in color.
- 3. ‘Maple Leaf’ exhibits unique foliage that is orange in color.
‘Maple Leaf’ can be most closely compared to the Heuchera cultivars ‘Vulcano’ and ‘Apricot’. ‘Vulcano’ is similar to ‘Maple Leaf’ in foliage shape. ‘Vulcano’ differs from ‘Maple Leaf’ in having foliage that is lighter orange in color and young foliage with matte surfaces. ‘Apricot’ is similar to ‘Maple Leaf’ in foliage color. ‘Apricot’ differs from ‘Maple Leaf’ in having young foliage with matte surfaces, flowers that are pink color, a smaller plant size and a less vigorous plant habit.
The accompanying colored photograph illustrates the overall appearance and distinct characteristics of the new Heuchera. The photograph was taken of a plant 18 months in age as grown in a polyethylene tunnel in a 27-cm container in Hantay, France.
The photograph in FIG. 1 provides a side view of the plant of ‘Maple Leaf’ in bloom.
The photograph in FIG. 2 provides a close up of the inflorescence of ‘Maple Leaf’.
The photograph in FIG. 3 provides a close up of the foliage of ‘Maple Leaf’.
The colors in the photograph 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.
The following is a detailed description of 18 month-old plants of the new cultivar as grown outdoors in 27-cm containers in Hantay, France. 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 2015 Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
