Abstract

A new and distinct cultivar of Monarda plant named ‘Balbalmurp’, characterized by its dark red-purple colored flowers, dark green-colored foliage having good powdery mildew resistance, and moderately vigorous, upright-compact growth habit, is disclosed.

Description

Latin name of genus and species of plant claimed: Monarda didyma.

Variety denomination: ‘Balbalmurp’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Monarda plant botanically known as Monarda didyma and hereinafter referred to by the cultivar name ‘Balbalmurp’.

The new cultivar originated in a controlled breeding program in Guadalupe, Calif. during May 2008. The objective of the breeding program was the development of Monarda cultivars that are early flowering, have good powdery mildew resistance, and a compact growth habit.

The new Monarda cultivar is the result of cross-pollination. The female (seed) parent of the new cultivar is ‘Pink Lace’, U.S. Plant Pat. No. 18,367, characterized by its red-purple colored inflorescences, dark green-colored foliage, and moderately vigorous, compact-upright growth habit. The male (pollen) parent of the new cultivar is Grande Parade ‘Acrade’, U.S. Plant Pat. No. 19,580, characterized by its purple-violet colored inflorescences, dark green-colored foliage, and vigorous, mounded growth habit. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated cross-pollination during September 2009 in a controlled environment in Guadalupe, Calif.

Asexual reproduction of the new cultivar by terminal stem cuttings since September 2009 in Guadalupe, Calif. and Elbum, Ill. has demonstrated that the new cultivar reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Balbalmurp’ as a new and distinct cultivar of Monarda plant:

- 1. Dark purple colored flowers;
- 2. Dark green-colored foliage having good powdery mildew resistance; and
- 3. Moderately vigorous, upright-compact growth habit.

Plants of the new cultivar differ from plants of the female parent primarily in flower color and from plants of the male parent primarily in flower color and growth vigor.

Of the many commercially available Monarda cultivars, the most similar in comparison to the new cultivar is ‘Pardon My Purple’, U.S. Plant Pat. No. 22,170. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Pardon My Purple’ in at least the following characteristics:

- 1. Plants of the new cultivar have a flower color different from plants of ‘Pardon My Purple’; and
- 2. Plants of the new cultivar have smaller diameter inflorescences than plants of ‘Pardon My Purple’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Balbalmurp’. The plants were grown in Elburn, Ill. in 1-gallon containers for approximately 36 weeks utilizing a soilless growth medium. This time period includes an approximately 12 week dormant period. Plants were pinched at time of transplant and again after 4 weeks of growth.

FIG. 2 illustrates a close-up view of an individual inflorescence of ‘Balbalmurp’.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2007 edition, except where general color terms of ordinary significance are used. The color values were determined in June 2013 under natural light conditions in West Chicago, Ill.

The following descriptions and measurements describe plants produced from cuttings from stock plants and grown in a glass-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown in Elburn, Ill. in 1-gallon containers for approximately 36 weeks utilizing a soilless growth medium. This time period includes an approximately 12 week dormant period. Plants were pinched at time of transplant and again after 4 weeks of growth. Greenhouse temperatures were maintained at approximately 50° F. to 70° F. (10.0° C. to 21.1° C.) during the day and approximately 35° F. to 50° F. (1.7° C. to 10.0° C.) during the night. No supplemental lighting was provided. Measurements and numerical values represent averages of typical plants.
