Botanical classification: Monarda didyma.

Variety denomination: ‘Purple Lace’.


The present invention relates to a new and distinct cultivar of Monarda didyma. The new cultivar will be referred to hereafter by its cultivar name, ‘Purple Lace’. ‘Purple Lace’ represents a new cultivar of bee balm suitable for use as a garden plant.

The new cultivar arose from on ongoing breeding program conducted by the Inventor in Lisserbroek, The Netherlands. ‘Purple Lace’ arose from a cross made in 2010 between ‘Cranberry Lace’ (U.S. Plant patent application Ser. No. 13/385,839, abandoned) as the female parent and ‘Pink Lace’ (U.S. Plant Pat. No. 18,367) as the male parent. The new cultivar was selected in July of 2011 as a single unique plant from the above cross.

Asexual propagation of the new cultivar was first accomplished by stem cuttings by the Inventor in 2012 in Lisserbroek, The Netherlands. Asexual propagation by cuttings and tissue culture has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.


The following traits have been repeatedly observed and represent the characteristics of the new Monarda. These attributes in combination distinguish ‘Purple Lace’ as a unique cultivar of Monarda.

    • 1. ‘Purple Lace’ exhibits inflorescences that are deep red purple in color.
    • 2. ‘Purple Lace’ exhibits strong stem that are yellow-green in color.
    • 3. ‘Purple Lace’ exhibits a compact plant habit with good basal branching.
    • 4. ‘Purple Lace’ reaches a height of about 36 cm.

The new cultivar of Monarda can be readily distinguished from other cultivars. The parent plants of ‘Purple Lace’, ‘Cranberry Lace’ and ‘Pink Lace’ are the closest comparison cultivars known to the Inventor. ‘Cranberry Lace’ differs from ‘Purple Lace’ in being slightly taller in height and in having inflorescences that are bright pink in color. ‘Pink Lace’ differs from ‘Purple Lace’ in being slightly taller in height and in having inflorescences that are lighter red-purple in color. ‘Purple Lace’ can also be compared to the cultivars ‘Fireball’ (U.S. Plant Pat. No. 14,235) and ‘Pink Supreme’ (U.S. Plant Pat. No. 14,204). Both differ from ‘Purple Lace’ in being much taller in height. In addition, ‘Fireball’ differs in having flowers that are redder in color and ‘Pink Supreme’ differs in having flowers that are pink in color.


The accompanying colored photographs illustrate the overall appearance and distinct characteristics of two year-old plants of the new Monarda as grown outdoors in a 17-cm container in Rijpwetering, The Netherlands.

The Photograph in FIG. 1 provides a side view of ‘Purple Lace’ in bloom.

The Photograph in FIG. 2 provides a view of an inflorescence of ‘Purple Lace’.

The Photograph in FIG. 3 provides a close-up view of a leaf of ‘Purple Lace’.

The colors in the photographs are as close as possible with digital photography techniques available and the color values cited in the detailed botanical description accurately describe the colors of the Monarda.


The following is a detailed description of two-year old plants of the new cultivar as grown outdoors in 17-cm containers in Rijpwetering, The Netherlands. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
