Description

BOTANICAL DESIGNATION AND CULTIVAR DENOMINATION

Botanical classification: Monarda didyma.

Variety denomination: ‘Lilac Lollipop’.

CROSS REFERENCE TO RELATED PLANTS FEDERAL SPONSORSHIP AND FUNDING

This plant invention was developed without federally sponsored research or development funding.

BACKGROUND OF THE INVENTION

The present invention relates to the new and distinct plant cultivar known as Monarda didyma ‘Lilac Lollipop’, and hereinafter also referred to solely as the cultivar ‘Lilac Lollipop’ 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. The female or seed parent is the unreleased proprietary hybrid Monarda dydima H9-06-01 (not patented) and the male or pollen parent is unknown but may have been any one of several plants and seedlings in the isolation breeding area since the pollen is efficiently spread long distances by insects. The plant was initially subjected to evaluation in the summer of 2012 in trial plots of the same nursery in Zeeland, Mich. Final evaluation was performed in the summer of 2013 wherein a single selected seedling was separated for eventual introduction and assigned the breeder identification number H10-26-3.

Monarda ‘Lilac Lollipop’ has been asexually propagated by stem cuttings 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 ‘Lilac Lollipop’ is unique from its parent and all other bee balm plants known to the inventor. The nearest comparison varieties are ‘Purple Rooster’ (not patented), ‘Leading Lady Lilac’ U.S. Plant Pat. No. 26,431 and ‘ACrade’ (U.S. Plant Pat. No. 19,580) in plant habit. Compared to ‘Purple Rooster’, the new plant has larger flowers that are lighter colored, a lavender lilac rather than the darker purple, and ‘Purple Rooster’ is significantly taller. ‘Lilac Lollipop’ is slightly shorter than the female parent and taller than ‘ACrade’ and also has a more reddish coloring to the flowers than ‘ACrade’ or the female parent. Compared to both ‘Leading Lady Lilac’ U.S. Plant Pat. No. 26,431 and ‘Leading Lady Plum’ U.S. Plant Pat. No. 26,447, the new plant does not have the darker purple spotting on the petals and is much lighter with less red than ‘Leading Lady Plum’.

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

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

• • 1. Moderate growth rate, intermediate height, compact, tightly clumping habit.
  • 2. Dark-green, powdery mildew resistant foliage.
  • 3. Reddish tinted stems.
  • 4. Lavender lilac flowers for a long period in summer.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the unique traits of ‘Lilac Lollipop’ and the overall appearance of the plant at two-years-old at 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.

DETAILED BOTANICAL DESCRIPTION

The following descriptions and color references are based on the 2001 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used. Monarda didyma ‘Lilac Lollipop’ has not been observed under all possible environments. The phenotype may vary slightly with different growing environments such as temperature, light, fertility, soil pH, moisture and maturity levels, but without any change in the genotype.
