plant named ‘Peppermint Patty’

- Walters Gardens, Inc

A new and distinct Heartleaf Bergenia plant, Bergenia plant named ‘Peppermint Patty’ with a dense mounded habit, medium to large-sized, densely-arranged, deep-green, glossy, obovate, evergreen foliage with serrate to dentate and ciliolate margins. The flowers are campanulate on large heavily-branched panicles over a long period beginning in spring. The flowers open white and develop pink centers and margins and hold up well in the garden as a landscape plant or as cut flowers. The new plant has a medium growth rate and the foliage is naturally resistant to deer and rabbit foraging.

Botanical designation: Bergenia hybrid.

Cultivar denomination: ‘Peppermint Patty’.


The first non-enabling disclosure of the claimed plant was Dec. 1, 2022, when the claimed plant was displayed as a photograph with a non-enabling brief description on a website maintained by Walters Gardens, Inc. The first plants of Bergenia ‘Peppermint Patty’ offered for sale were by Walters Gardens, Inc. on Jul. 12, 2022. Walters Gardens, Inc. obtained the new plant and all information about the new plant directly from the inventor. No other plants have been sold earlier than this date 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 disclosure within one year was either derived directly or indirectly from the inventor.


The present invention relates to the new and distinct Heartleaf Bergenia herein also referred to as Bergenia ‘Peppermint Patty’, by the cultivar name, ‘Peppermint Patty’, or as the new plant. The new plant was hybridized by the inventor on Mar. 14, 2014, from a cross-pollination plant of Bergenia ‘Sakura’ (not patented) as the female or seed parent and the proprietary unreleased unnamed hybrid known only as 12-1-6 (not patented) as the male or pollen parent. The cross was performed in a greenhouse of a wholesale perennial grower in Zeeland, Michigan. The single seedling represented by ‘Peppermint Patty’ was selected from a group of seedlings by the inventor, isolated, compared in subsequent years to other Bergenia and subsequently found to be different from all cultivars known to the discoverer, and given the breeder code 14-13-111 through the remaining evaluation process.

Asexual propagation at the same nursery in Zeeland, MI, USA initially by basal cuttings and later by shoot tip sterile tissue culture has shown ‘Peppermint Patty’ to be stable and reproduce true to type in successive generations since late summer of 2016.


Bergenia ‘Peppermint Patty’ has not been observed in all possible environmental conditions. The phenotype may vary slightly with changes in environments such as light intensity, fertility, water availability, etc. without any variations in genotype.

Bergenia ‘Peppermint Patty’ is distinct from all cultivars known to the inventor in the following traits:

    • 1. Dense mounded habit;
    • 2. Medium to large-sized, densely-arranged, deep-green, glossy, obovate, evergreen foliage with ciliolate margins;
    • 3. Heavily-branched, large panicles of large campanulate flowers over a long period in spring;
    • 4. Flowers open white and develop pink centers and margins;
    • 5. Medium growth rate;
    • 6. Foliage is naturally resistant to deer and rabbits.

Plants of Bergenia ‘Peppermint Patty’ are most similar to: ‘Apple Blossom’ U.S. Plant Pat. No. 15,101, ‘Flirt’ U.S. Plant Pat. No. 26,355, ‘Miss Piggy’ U.S. Plant Pat. No. 32,132, ‘Fairytale Romance’ U.S. Plant patent application Ser. No. 17/803,929, and ‘Spring Fling’ U.S. Plant Pat. 26,337.

‘Apple Blossom’ has a slightly smaller habit with flowers that are a light pink, and the leaf margins that are not ciliolate. ‘Miss Piggy’ has a slightly smaller habit and deeper pink flowers, and the foliage does not have ciliolate margins. ‘Fairytale Romance’ has a smaller habit, the flowers are smaller and more solid light-pink, and the foliage is smaller without ciliolate margins. ‘Spring Fling’ has a shorter habit and denser panicles of deeper pink flowers.

The female parent, ‘Sakura’, has a smaller habit with shorter, smaller peduncles, deeper pink flowers, and foliage that is smaller and without ciliolate margins. The male parent has smaller white flowers at least one week earlier, and the foliage is more deciduous with a more ciliolate margin.


The color drawings illustrate the overall characteristics of Bergenia ‘Peppermint Patty’ as a three-year-old plant. The colors are as true as reasonably possible given the technology available. The color values may vary slightly depending on light intensity and quality.

FIG. 1 shows the new plant in a full-sun landscape environment.

FIG. 2 shows a close-up of the young and mature flowers of the new plant in a partially-shaded greenhouse.


The following description is based on two-year-old plants growing in a partially-shaded greenhouse and in an outdoor full-sun display garden in Zeeland, MI, USA. Except for ordinary dictionary color usage, color references are according to The Royal Horticultural Society Colour Chart, 2015 edition. The new plant has not been observed in all possible growing conditions and may vary in phenotypic characteristics based on water availability, light conditions, fertilizer, temperatures, etc. without varying in genotypic characteristics.
