plant named ‘Grape Timeless’

- Walters Gardens, Inc

The new and distinct hybrid of Heuchera plant named ‘Grape Timeless’ with medium-sized, shallowly lobed, glossy foliage with rounded apices and lobes. Tightly-branched, upright panicles are produced from early summer to early fall for about fourteen weeks displaying large, bright, rosy-pink flowers. The new plant has a compact habit, is vigorous and produces showy, long-flowering, herbaceous, perennial mounds of leaves beginning the season purplish-red and developing a greyed-purple overlay and dark charcoal-purple surrounding the veins, effective as a specimen plant, en masse, or as a container plant in the landscape.

Description

Botanical denomination: Heuchera hybrid.

Variety denomination: ‘Grape Timeless’.

STATEMENT REGARDING PRIOR DISCLOSURES UNDER 37 CFR 1.77(B)(6)

The first public disclosure of the claimed plant, in the form of a website to the public and email release to customers, was made by Walters Gardens, Inc. on Feb. 1, 2018 followed by the Walters Gardens, Inc. Summer 2018—Spring 2019 catalog. The first public sales of Heuchera ‘Grape Timeless’ was by Walters Gardens, Inc. on Jul. 23, 2018. Walters Gardens, Inc. obtained the new plant and information about the new plant directly from the inventor. No plants of Heuchera ‘Grape Timeless’ have been sold, in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior the filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Coral Bells in the Saxifragaceae family and given the cultivar name of Heuchera ‘Grape Timeless’. ‘Grape Timeless’ was hybridized by the inventor on Feb. 11, 2015 at a wholesale perennial nursery in Zeeland, Mich., USA. The seed or female parent was ‘Berry Timeless’ U.S. Plant Pat. No. 26,357 and the pollen or male parent was a proprietary unreleased hybrid known as 13-715-1.

Heuchera ‘Grape Timeless’ was first selected in the fall of 2016 and passed final evaluation in the fall of 2017 from among many other seedlings from the same cross and hundreds of other crosses and assigned the breeder code 15-42-2 through the remaining evaluation process. Heuchera ‘Grape Timeless’ has been asexually propagated initially by basal cuttings at the same nursery in Zeeland, Mich. in 2016 and also by sterile, shoot-tip, tissue culture propagation, and the resultant plants have remained stable and continued to exhibit the same characteristics as the original plant for multiple generations.

BRIEF SUMMARY OF THE INVENTION

The nearest comparison varieties include: the female parent ‘Berry Timeless’, ‘Grape Expectations’ U.S. Plant Pat. No. 26,894, ‘Wildberry’ U.S. Plant patent application Ser. No. 16/350,491, ‘Wild Rose’ U.S. Plant Pat. No. 29,923, and ‘Electric Plum’ U.S. Plant Pat. No. 29,924 and the two copending U.S. Plant Patent Applications ‘Timeless Glow’ U.S. Plant patent application Ser. No. 16/350,865 and ‘Timeless Treasure’ U.S. Plant patent application Ser. No. 16/350,856. ‘Berry Timeless’ has a similar profusion of flowers throughout the season but the flower color is lighter pink and the foliage is light green with slight silvering between the veins. ‘Grape Expectations’ has foliage with less dissected lobes and the flowers are larger, creamy-white for a shorter season and on taller stems. ‘Wildberry’ has less silver between the veins and the flowers are white and for a shorter period. ‘Wild Rose’ has more silver overlay on the leaf, the leaves and habit are larger and the flowers are present over a shorter season. ‘Electric Plum’ has lighter pink emerging leaves in the spring, the leaves are more rounded and light pink flowers are produced for a shorter season. The male parent has different colored foliage and the flowers are produced over a shorter period. ‘Timeless Glow’ has chartreuse-yellow foliage with a silver overlay and intense, rose-pink flowers for a similarly long period. ‘Timeless Treasure’ has small pewter leaves with dark mahogany veins and stems and large rosy-pink flowers for a similarly long period. Heuchera ‘Grape Timeless’ differs from its parents as well as all other coral bells known to the applicant in the following combined traits:

    • 1. The medium-sized, flat, glossy foliage has rounded apices and lobes.
    • 2. Leaf blades begin season purplish-red and develop greyed-purple overlay between the charcoal-purple area surrounding the veins.
    • 3. Leaf blades are shallowly dissected with apices rounded and mucronulate.
    • 4. Flowers are outwardly-facing, bright, rosy-pink on dark purple stems.
    • 5. Flowering period begins in early summer and continues for about fourteen weeks into early fall with repeat panicles.
    • 6. Compact, short-branched panicles of deep burgundy display flowers at multiple nodes beginning under foliage.
    • 7. The new plant is vigorous and produces compact clumps and many individual leaves.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of Heuchera ‘Grape Timeless’ demonstrate the overall appearance of the plant including the unique traits of a plant in a full sun trial block in Zeeland, Mich. The colors are as accurate as reasonably possible with color reproductions. Some slight variation of color may occur as a result of lighting quality, intensity, wavelength, and direction or reflection.

DETAILED BOTANICAL DESCRIPTION

The following description is based on three-year-old plants growing in a partially shaded greenhouse in Zeeland, Mich., USA. The new plant has not been grown under all possible environments and may phenotypically appear different under different conditions such as light, temperatures, fertilizer, and water, without any difference in genotype. The color descriptions used are from the 2015 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used.
