USPP34434P2 - Monarda plant named ‘Pardon My Rose’ - Google Patents

Abstract

The new and distinct cultivar of ornamental cultivar of bee balm plant named Monarda didyma ‘Pardon My Rose’ has short, compact, basally branching stems, dark green foliage with strong resistance to powdery mildew and numerous large flower heads of intense rose-pink-colored flowers creating excellent flower coverage. The new plant is attractive and useful in the garden landscape as a specimen, en masse, or as a container plant.

Description

Botanical classification: Monarda didyma.

Variety denomination: ‘Pardon My Rose’.

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

The first non-enabling disclosure of the claimed plant was made on Dec. 1, 2020 in the form of photograph and brief description on a website operated by Walters Gardens, Inc., followed on May 21, 2021 by a photograph and brief description in the “Walters Gardens 2021-2022 Catalog.” Walters Gardens, Inc obtained the plant and all information relating thereto, from the inventor. The first sales of the new plant were on May 3, 2021 by Walters Gardens, Inc. to Bachman's Nursery, Inc. No plants of Monarda ‘Pardon My Rose’ 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 to 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 the new and distinct cultivar of bee balm plant, botanically known as Monarda didyma ‘Pardon My Rose’, and hereinafter also referred to solely as the cultivar ‘Pardon My Rose’ or the “new plant”. The new plant was selected from self-pollination on Jun. 17, 2015 from an unreleased, proprietary hybrid known only by the hybridizer code 14-47-1 in a designated hybridizing plot of a wholesale perennial nursery in Zeeland, Mich., USA. The new plant was a single seedling selection originally made in the summer of 2017 from the seeds that were sown in the fall of 2015 and the plant was assigned the breeder code of 15-34-10. Further selection was completed in the trial fields of a wholesale perennial nursery in Zeeland, Mich. in the summer of 2019.

The new plant has been asexually propagated by shoot tip cuttings originally in 2018 at the same nursery in the greenhouses in Zeeland, Mich., and the subsequent asexually propagated plants found to be stable, true to type and identical to the original selection.

BRIEF SUMMARY OF THE PLANT

Monarda didyma ‘Pardon My Rose’ is unique from its parents and all other Bee Balm plants known to the inventors. The nearest comparison varieties are: ‘Pardon My Cerise’ U.S. Plant Pat. No. 29,234, ‘Berry Taffy’ U.S. Plant patent application Ser. No. 17/300,434, ‘Cherry Pops’ U.S. Plant Pat. No. 27,618, and ‘Fire Marshall’ U.S. Plant Pat. No. 23,286. ‘Pardon My Cerise’ has a similar habit with flowers that are a deep cherry-red. ‘Berry Taffy’ has a more compact shorter habit with flowers that are hot raspberry-pink. ‘Cherry Pops’ has a slightly taller habit with flowers that are cherry-red. ‘Fire Marshall’ has a taller habit with flowers that are deeper red.

‘Petite Delight’ U.S. Plant Pat. No. 10,784 is slightly shorter than the new plant and the flowers are smaller and more purplish-red. ‘AChall’ U.S. Plant Pat. No. 19,582 is slightly shorter than the new plant, has flowers that are much darker purplish-red. Both ‘Petite Delight’ and ‘AChall’ showed some sensitivity to powdery mildew.

The parent plant has a taller habit and the flower color is more purplish color and less reddish.

The following are traits of Monarda didyma ‘Pardon My Rose’ that in combination distinguish it from all other bee balm known to the inventor:

• • 1. Short, winter-hardy, compact, vigorous, clumping habit;
  • 2. Dark-green leaves that are strongly resistant to powdery mildew;
  • 3. Large flower heads of intense, rose-pink-colored flowers for a long period in summer with excellent flower coverage;
  • 4. Flowers are subtended by burgundy-colored bracts.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the unique traits of ‘Pardon My Rose’ and the overall appearance of the plant at three-years old in the full sun trial garden of a wholesale perennial nursery in Zeeland, Mich. The colors are as accurate as reasonably possible with color reproductions. Variation in ambient light spectrum, source and direction may cause the appearance of minor variation in color.
