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

The first public disclosure of the claimed plant, in the form of a sale, was made by Walters Gardens, Inc. on Jul. 7, 2021. Prior to that, on Dec. 1, 2020 the claimed plant was displayed with a non-enabling photograph and brief description in a website operated by Walters Gardens, Inc., and on May 21, 2021 as a non-enabling photograph and brief description in the 2021-2022 Catalog by Walters Gardens, Inc., who obtained the plant and all information relating thereto, from the inventor. No plants of Monarda ‘Pardon My Lavender II’ 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 the new and distinct cultivar of bee balm plant, botanically known as Monarda didyma ‘Pardon My Lavender II’, and hereinafter also referred to solely as the cultivar ‘Pardon My Lavender II’ or the “new plant”. The new plant was selected from seed collected by the hybridizer from a self-pollination on Jun. 17, 2015 at a nursery in Zeeland, Mich., USA of a proprietary unreleased hybrid known only as 14-57-3 not patented. The plant was a single selection originally made in the summer of 2017 from the seeds that were sown in the fall of 2015, and the new plant was assigned the temporary breeder code of 15-54-5.

The new plant has been asexually propagated by division followed by basal shoot tip cuttings originally in 2017 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 Lavender II’ is unique from its parents and all other bee balm plants known to the inventors. The nearest comparison varieties are: ‘Pardon My Lavender’ U.S. Plant Pat. No. 28,770, ‘Leading Lady Orchid’ U.S. Plant Pat. No. 33,132, ‘Leading Lady Plum’ U.S. Plant Pat. No. 26,447, ‘Lilac Lollipop’ U.S. Plant Pat. No. 27,571 ‘Pardon My Purple’ U.S. Plant Pat. No. 22,170 and ‘Purple Lace’ U.S. Plant Pat. No. 25,615.

‘Pardon My Lavender’ has a lighter lavender-pink flower without the anthocyanin on the bracts and foliage. ‘Leading Lady Orchid’ and ‘Leading Lady Plum’ have taller habits, the former with orchid-pink flowers and the latter with deeper magenta-pink flowers, both with darker spotting on the lower petal. ‘Lilac Lollipop’ has a slightly taller and narrower habit with less vigor and the flower is lavender-lilac. ‘Pardon My Purple’ has flowers of deeper fuchsia-purple. ‘Purple Lace’ has a deeper reddish-purple flower.

Comparison with the parent 14-57-3 has a taller habit with lighter-colored flowers that do not cover the plant as completely.

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

• • 1. Short, winter-hardy, compact, vigorous, clumping habit;
  • 2. Medium to dark-green leaves with good resistance to powdery mildew;
  • 3. Large-sized heads of lavender-pink colored flowers for a long period in summer with excellent flower coverage;
  • 4. Flower heads subtended by burgundy-colored bracts.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the unique traits of ‘Pardon My Lavender II’ and the overall appearance of the plant at two-years old in the full sun trial garden of a 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.
