plant named ‘Miss Piggy’

Abstract

A new and distinct Heartleaf Bergenia plant, Bergenia plant named ‘Miss Piggy’ with low, spreading, mounded habit, large, densely-arranged, deep-green, glossy, obovate, evergreen and pink campanulate flowers on heavily-branched, large panicles over a four-week period beginning in early spring. The flowers hold up well in the garden as a landscape plant or as cut flowers. The new plant has a medium growth rate and is naturally resistant to deer and rabbit foraging.

Description

Botanical designation: Bergenia crassifolia (L.) Fritsch; [Bergenia cordifolia (Haw.) Sternb.].

Cultivar denomination: ‘Miss Piggy’.

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

The original disclosure of the claimed plant was made by Walters Gardens, Inc. on Dec. 1, 2018 when the claimed plant was displayed as a photograph with a non-enabling brief description in a website maintained by Walters Gardens, Inc., who obtained the plant and all information relating thereto, from the inventor. No plants of Bergenia ‘Miss Piggy’ have been sold, in this country or anywhere in the world as of the filing date of this application, 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.

BACKGROUND OF THE PLANT

The present invention relates to the new and distinct Heartleaf Bergenia herein also referred to as Bergenia ‘Miss Piggy’, by the cultivar name, ‘Miss Piggy’, or as the new plant. The new plant was hybridized by the inventor on Apr. 3, 2013 from a self-pollinated plant of Bergenia ‘Sakura’ (not patented), in a greenhouse of a wholesale perennial grower in Zeeland, Mich. The single seedling represented by ‘Miss Piggy’ was selected from a group of seedlings by the inventor, isolated and compared in subsequent years to other Bergenia and subsequently found to be different from all cultivars known to the discoverer and eventually given the breeder code 13-9-31.

Asexual propagation at the same nursery in Zeeland, Mich., USA initially by division and later by shoot tip sterile tissue culture has shown ‘Miss Piggy’ to be stable and reproduce true to type in successive generations since late summer of 2015.

SUMMARY OF THE PLANT

Bergenia ‘Miss Piggy’ 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, however any variation in genotype.

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

• • 1. Low, spreading, mounded habit;
  • 2. Large, densely-arranged, deep-green, glossy, obovate, evergreen foliage;
  • 3. Heavily-branched, large panicle with pink bell-shaped flowers over a long period in spring holds up well in the garden or as a cut flower;
  • 4. Medium growth rate;
  • 5. Naturally resistant to deer and rabbit.

Plants of Bergenia ‘Miss Piggy’ are most similar to ‘Flirt’ U.S. Plant Pat. No. 26,355 and ‘Pink Dragon’ (not patented). ‘Miss Piggy’ has larger and broader foliage and is taller in habit of both foliage and flower than both ‘Flirt’ and ‘Pink Dragon’. ‘Flirt’ has smaller inflorescences and deeper pink flowers over a shorter period of time. ‘Pink Dragon’ has slightly deeper pink flowers on smaller inflorescences. Compared to ‘Sakura’, ‘Miss Piggy’ has more consistent pink flower color, a larger canopy of foliage, and broader, more substantial leaves.

BRIEF DESCRIPTION OF THE DRAWINGS

The color drawings illustrate the overall characteristics of Bergenia ‘Miss Piggy’ as a four-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.

DETAILED BOTANICAL DESCRIPTION
