plant named ‘Juliette’

Abstract

A new and distinct cultivar of Monarda plant named ‘Juliette’, characterized by its upright and tall plant habit; freely branching habit; dark green-colored leaves; freely flowering habit; large inflorescences with light red purple to purple-colored flowers; relatively resistant to Powdery Mildew; and relatively tolerant to low temperatures.

Description

Botanical designation: Monarda L.

Cultivar denomination: ‘JULIETTE’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Monarda plant, botanically known as Monarda L., typically grown as a cut flower plant and hereinafter referred to by the name ‘Juliette’.

The new Monarda plant is a product of a planned breeding program conducted by the Inventor in Oude-Wetering, The Netherlands. The objective of the breeding program is to create new upright and freely branching Monarda plants with numerous attractive flowers and disease-resistance.

The new Monarda plant originated from an open-pollination in 2015 of an unidentified selection of Monarda L., not patented, as the female, or seed, parent with an unknown selection of Monarda L. as the male, or pollen, parent. The new Monarda plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination grown in a controlled environment in Oude-Wetering, The Netherlands in 2016.

Asexual reproduction of the new Monarda plant by softwood vegetative cuttings in Lisserbroek, The Netherlands, since 2016 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 ‘Juliette’. These characteristics in combination distinguish ‘Juliette’ as a new and distinct Monarda plant:

• • 1. Upright and tall plant habit.
  • 2. Freely branching habit.
  • 3. Dark green-colored leaves.
  • 4. Freely flowering habit.
  • 5. Large inflorescences with light red purple to purple-colored flowers.
  • 6. Relatively resistant to Powdery Mildew.
  • 7. Relatively low temperature tolerant.

Plants of the new Monarda differ primarily from plants of the female parent selection in plant height as plants of the new Monarda are taller than plants of the female parent selection. In addition, plants of the new Monarda are more tolerant to Powdery Mildew than plants of the female parent selection.

Plants of the new Monarda can be compared to plants of Monarda didyma ‘Pink Lace’, disclosed in U.S. Plant Pat. No. 18,367. In side-by-side comparisons, plants of the new Monarda differ primarily from plants of ‘Pink Lace’ in the following characteristics:

• • 1. Plants of the new Monarda are taller than plants of ‘Pink Lace’.
  • 2. Plants of the new Monarda have slightly darker red purple-colored flowers than plants of ‘Pink Lace’.

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

• • 1. Plants of the new Monarda flower for a longer period of time than plants of ‘Squaw’.
  • 2. Plants of the new Monarda have red purple-colored flowers whereas plants of ‘Squaw’ have red-colored flowers.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in 17-cm containers in an outdoor nursery in Lisserbroek, 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 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.
