Abstract

A new and distinct cultivar of Crapemyrtle plant named ‘JM6’, characterized by its upright to somewhat outwardly spreading plant habit; freely branching habit; vigorous and sturdy growth habit; dark greyed purple-colored leaves; numerous inflorescences with white-colored flowers; and good garden performance and pathogen resistance.

Description

Botanical designation: Lagerstroemia indica ‘JM6’.
Cultivar denomination: ‘JM6’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Crapemyrtle plant, botanically known as Lagerstroemia indica ‘JM6’ and hereinafter referred to by the name ‘JM6’.
The new Crapemyrtle plant is a product of a planned breeding program conducted by the Inventor in Poplarville, Miss. The objective of the breeding program was to develop new vigorous and freely-branching Crapemyrtle plants with dark-colored leaves and attractive flower colors.
The new Crapemyrtle plant originated from a cross-pollination conducted by the Inventor during the summer of 2015 of Lagerstroemia indica ‘Ebony and Ivory’, not patented, as the female, or seed, parent with Lagerstroemia indica ‘Natchez’, not patented, as the male, or pollen, parent. The new Crapemyrtle plant was discovered and selected by the Inventor in May, 2016 as a single flowering plant from within the progeny of the stated cross-pollination in a controlled nursery environment in Poplarville, Miss.
Asexual reproduction of the new Crapemyrtle plant by vegetative softwood cuttings in a controlled greenhouse environment in Poplarville, Miss. since August, 2016 has shown that the unique features of the new Crapemyrtle plant are stable and reproduced true to type in successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
Plants of the new Crapemyrtle 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 ‘JM6’. These characteristics in combination distinguish ‘JM6’ as a new and distinct Crapemyrtle plant:
    • 1. Upright to somewhat outwardly spreading plant habit.
    • 2. Freely branching habit.
    • 3. Vigorous and sturdy growth habit.
    • 4. Dark greyed purple-colored leaves.
    • 5. Numerous inflorescences with white-colored flowers.
    • 6. Good garden performance and pathogen resistance.
Plants of the new Crapemyrtle can be compared to plants of the female parent, ‘Ebony and Ivory’. Plants of the new Crapemyrtle differ primarily from plants of ‘Ebony and Ivory’ in the following characteristics:
    • 1. Plants of the new Crapemyrtle are larger than plants of ‘Ebony and Ivory’.
    • 2. Plants of the new Crapemyrtle are more vigorous than plants of ‘Ebony and Ivory’.
Plants of the new Crapemyrtle can be compared to plants of the male parent, ‘Natchez’. Plants of the new Crapemyrtle differ primarily from plants of Natchez in leaf color as plants of the new Crapemyrtle have dark greyed purple-colored leaves whereas plants of ‘Natchez’ have light green-colored leaves.
Plants of the new Crapemyrtle can be compared to plants of the Lagerstroemia L. ‘PIILAG-I’, disclosed in U.S. Plant Pat. No. 23,168. In side-by-side comparisons, plants of the new Crapemyrtle differ primarily from plants of ‘PIILAG-I’ in the following characteristics:
    • 1. Plants of the new Crapemyrtle are taller and are more vigorous than plants of ‘PIILAG-I’.
    • 2. Plants of the new Crapemyrtle have dark greyed purple-colored leaves whereas plants of ‘PIILAG-I’ have dark green-colored leaves.
Plants of the new Crapemyrtle can be compared to plants of the Lagerstroemia indica ‘Ebony Glow’, not patented. In side-by-side comparisons, plants of the new Crapemyrtle differ primarily from plants of ‘Ebony Glow’ in the following characteristics:
    • 1. Leaves of plants of the new Crapemyrtle grow faster than plants of ‘Ebony Glow’.
    • 2. Plants of the new Crapemyrtle have larger leaves than plants of ‘Ebony Glow’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Crapemyrtle plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Crapemyrtle plant.
The photograph on the first sheet (FIG. 1 of 2) is a side perspective view of a typical plant of ‘JM6’ grown in a container in an outdoor nursery.
The photograph on the second sheet (FIG. 2 of 2) is a close-up view of a typical flowering plant of ‘JM6’ grown in a container in an outdoor nursery.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown in 7-gallon containers in Park Hill, Okla. and Fort Worth, Tex. during the summer in outdoor nurseries and under cultural conditions which closely approximate commercial Crapemyrtle production. During the production of the plants, day temperatures averaged 33° C. and night temperatures averaged 14° C. Plants were three years when the photographs and the description were taken.
