BOTANICAL DESIGNATION AND CULTIVAR DENOMINATION

Botanical classification: Monarda didyma L.

Variety denomination: ‘Cherry Pops’.

BACKGROUND OF THE INVENTION

The present invention relates to the new and distinct cultivar botanically known as Monarda didyma ‘Cherry Pops’, and hereinafter also referred to solely as the cultivar ‘Cherry Pops’ or the “new plant”. The new plant was the subject of an open pollination in summer of 2010 at a wholesale perennial nursery in Zeeland, Mich., USA. Seed was harvested by the inventor in the fall of 2010 and later the individual seedling later assigned the breeder identification number H10-09-51. The female or seed parent is the unreleased proprietary hybrid Monarda didyma HK9-44-40 (not patented) and the male or pollen parent is unknown but may have been any one of a number of plants and seedlings in the breeding area since the pollen is efficiently spread long distances by insects. The plant was initially subjected to evaluation in the summer of 2011 in trial plots of the same nursery in Zeeland, Mich. The new plant was collected and set apart as a single selected seedling in July of 2012 and separated out for final evaluation in the summer of 2013 by Hans Hansen.

The plant has been asexually propagated by stem cuttings as early as the summer of 2012 at the same nursery in the greenhouses in Zeeland, Mich., and the subsequent asexually propagated plants found to be stable and identical to the original selection.

BRIEF SUMMARY OF THE PLANT

Monarda didyma ‘Cherry Pops’ is unique from its parent and all other bee balm plants known to the inventor. The nearest comparison varieties are ‘Fireball’ U.S. Plant Pat. No. 14,235 and ‘AChall’ (U.S. Plant Pat. No. 19,582) in plant habit ‘Jacob Cline’ (not patented), ‘Colrain Red’ (not patented), ‘Fire Marshall’ U.S. Plant Pat. No. 23,286, ‘Fireball’ U.S. Plant Pat. No. 14,235, ‘Mondid 0803’ U.S. Plant Pat. No. 17,513, ‘Cambridge Scarlet’ (not patented) and ‘Gardenview Scarlet’ (not patented) along with ‘Fireball’ and ‘AChall’ all have a reddish based flower color. Compared to ‘Cherry Pops’ all of the above have more purplish tinting or deeper red in flower color than ‘Cherry Pops’ which has a lighter cherry red flower color. Compared to the parent, the new plant is shorter and has more cherry red flower color.

The table below shows a more detailed comparison of these cultivars in terms of flower color and height.

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

• • 1. Rapid-growing, intermediate height, compact, tightly clumping habit.
  • 2. Dark-green, powdery mildew resistant foliage.
  • 3. Dark purplish tinted stems.
  • 4. Cherry red flowers for a long period in summer.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the unique traits of ‘Cherry Pops’ and the overall appearance of the plant at three-years-old in the full sun trial garden of a nursery in Zeeland, Mich. The colors are as accurate as reasonably possible with current color reproduction technology. Deviation in ambient light spectrum, source and direction may cause the appearance of minor variation in color.
