Title: Monarda Plant Named ‘MONARD0039’

Applicant: Henricus Maria Joseph Holtmaat

Filed: Concurrently with this application Ser. No. 15/732,923

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Monarda plant, botanically known as Monarda didyma, typically grown as a container plant and hereinafter referred to by the name ‘MONARD0044’.

The new Monarda plant is a product of a planned breeding program conducted by the Inventor in Zuidwolde, The Netherlands. The objective of the breeding program is to create new Monarda plants with attractive flowers and tolerance to Powdery Mildew.

The new Monarda plant originated from a cross-pollination in July, 2014 of two unnamed selections of Monarda didyma, not patented. The new Monarda plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled environment in Zuidwolde, The Netherlands in July, 2016.

Asexual reproduction of the new Monarda plant by vegetative terminal cuttings in Zuidwolde, The Netherlands, since March, 2017 has shown that the unique features of this new Monarda plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Monarda have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘MONARD0044’. These characteristics in combination distinguish ‘MONARD0044’ as a new and distinct Monarda plant:

- 1. Broadly upright plant habit.
- 2. Dark green-colored leaves.
- 3. Freely flowering habit.
- 4. Large inflorescences with purple violet-colored flowers.
- 5. Long flowering period.
- 6. Tolerant to Powdery Mildew.

Plants of the new Monarda differ primarily from plants of the parent selections in plant uniformity as plants of the new Monarda are more uniform than plants of the parent selections.

Plants of the new Monarda can be compared to plants of Monarda didyma ‘MONARD0039’, disclosed in U.S. Plant Patent filed concurrently Ser. No. 15/732,923. In side-by-side comparisons, plants of the new Monarda differ primarily from plants of ‘MONARD0039’ in flower color as plants of ‘MONARD0039’ have purple-colored flowers. In addition, plants of the new Monarda are more compact than plants of ‘MONARD0039’.

Plants of the new Monarda can be compared to plants of Monarda didyma ‘Purple Ann’, not patented. In side-by-side comparisons, plants of the new Monarda differ primarily from plants of ‘Purple Ann’ in the following characteristics:

- 1. Plants of the new Monarda are more freely flowering than plants of ‘Purple Ann’.
- 2. Plants of the new Monarda are more tolerant to Powdery Mildew than plants of ‘Purple Ann’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the late summer and early autumn in 19-cm containers in an outdoor nursery in Zuidwolde, The Netherlands and under cultural practices typical of commercial Monarda production. During the production of the plants, day temperatures ranged from 18° C. to 30° C. and night temperatures ranged from 6° C. to 18° C. Plants were one year old when the photographs and the description were taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
