Description

Botanical classification: Heuchera hybrid.

Cultivar designation: ‘Apricot’.

BACKGROUND OF THE INVENTION

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 ‘Apricot’.

The new cultivar was discovered as a whole plant mutation in a trial field by the Inventor in Hantay, France in June of 2011. The trial field contained hundreds of cultivars and proprietary seedlings of Heuchera from the Inventor's breeding program. The parentage of ‘Apricot’ is therefore unknown.

Asexual propagation of the new cultivar was first accomplished under the direction of the Inventor by in vitro propagation initiated using meristem tissue in Rijswijk, The Netherlands in 2011. Asexual propagation of the new cultivar by stem cuttings and 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 ‘Apricot’ as a new and unique cultivar of Heuchera.

    • 1. ‘Apricot’ exhibits leaves that are bronze-orange in color.
    • 2. ‘Apricot’ exhibits a compact plant habit with a tight mound of foliage.
    • 3. ‘Apricot’ exhibits an abundance of flowering stems.
    • 4. ‘Apricot’ exhibits medium pink flowers on dark red-purple flowering stems.

‘Apricot’ can be most closely compared to the Heuchera cultivars ‘Caramel’ (U.S. Plant Pat. No. 16,560) and ‘Vulcano’ (U.S. Plant Pat. No. 25,625). Both are similar to ‘Apricot’ in foliage coloration. ‘Caramel’ differs from ‘Apricot’ in having leaves that are slightly lighter in color and smaller in size with deeper lobed margins, and in rarely or sparsely producing flowering stems. ‘Vulcano’ differs from ‘Apricot’ in having leaves that are lighter in color with more conspicuous veins, flowers that are red in color and in having a shorter plant height.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Heuchera. The photographs were taken of a plant one year in age as grown outdoors in a 8.7-liter container in Hillegom, The Netherlands.

The photograph in FIG. 1 provides a side view of the plant habit of ‘Apricot’ in bloom.

The photograph in FIG. 2 provides a close-up view of the flowers of ‘Apricot’.

The photograph in FIG. 3 provides a close-up view of a leaf of ‘Apricot’.

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 1-year old plants of the new cultivar as grown outdoors in a 8.7-liter container in Hillegom, The Netherlands. 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.
