USPP31558P3 - Crapemyrtle plant named ‘DJ 06-14’ - Google Patents

Abstract

A new crapemyrtle plant has deep, uniform purple foliage and stems; a deep raspberry pink/red flower color; an intermediate upright growth habit; and powdery mildew and Cercospera resistance.

Description

Latin name of the genus and species of the plant claimed: ‘DJ 06-14’ is a Crapemyrtle plant that is a Lagerstroemia hybrid.

Variety denomination: The new crapemyrtle plant claimed is a variety denominated ‘DJ 06-14’.

BACKGROUND OF THE INVENTION

The present invention relates to the discovery of a new and distinct cultivar of the ornamental flowering shrub Lagerstroemia indica x Lagerstroemia fauriei, commonly known as crapemyrtle, and hereafter referred to by the varietal denomination ‘DJ 06-14’, as herein described and illustrated.

The new crapemyrtle originated from open pollinated seed of a patented plant, ‘Chocolate Mocha’ Crapemyrtle (U.S. Plant Pat. No. 21,540). ‘DJ 06-14’ was selected from plants grown at a horticultural farm in Watkinsville, Ga. The seedlings were planted in containers and selections were made for plants based on the following criteria:

• • 1.) Intermediate, upright growth habit
  • 2.) Powdery mildew resistance
  • 3.) Flower color and quality
  • 4.) Deep purple foliage and stem color
    ‘DJ 06-14’ was selected in September 2014.

Asexual reproduction by traditional vegetative cuttings since 2014 at the Horticulture Farm in Watkinsville, Ga. has shown that the distinguishing characteristics of the new crapemyrtle variety, ‘DJ 06-14’ are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

‘DJ 06-14’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with changes in light, temperature, soil and rainfall amount, however, any variance in genotype.

The following traits have been observed and represent the characteristics of the new cultivar. Asexual propagation by cuttings has proven that these characteristics are firmly fixed in succeeding asexually propagated generations. In combination, these characteristics distinguish ‘DJ 06-14’ from all other varieties known to the inventor:

• • 1.) Deep, uniform, purple foliage and stems;
  • 2.) Deep raspberry pink/red flower color;
  • 3.) Intermediate, upright growth habit; and
  • 4.) Powdery mildew and Cercospera resistance.

‘DJ 06-14’ is distinguished from its parent plant Lagerstroemia indica x Lagerstroemia fauriei ‘Chocolate Mocha’ by its improved, more consistent, deeper purple foliage and its larger, raspberry pink/red flower color. ‘DJ 06-14’, after 3 years of evaluation, has proven to be more resistant to powdery mildew and Cercospera than ‘Chocolate Mocha’.
