plant named ‘Cherry Mocha’

Abstract

The new and distinct crape myrtle plant named Lagerstroemia ‘Cherry Mocha’ has a dense, compact, narrow, upright habit, is ground hardy to at least USDA zone 6, has glossy burgundy foliage slowly developing into deep green with burgundy tinting. The flowers are fragrant, large and cherry-red colored arising from shiny red buds.

Description

Genus and species of plant claimed: Lagerstroemia (L.) hybrid.

Variety denomination: ‘Cherry Mocha’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lagerstroemia plant, commonly known as crape myrtle, and hereinafter referred to by the cultivar name ‘Cherry Mocha’ or the “new plant.” ‘Cherry Mocha’ is grown primarily as an ornamental for landscape use and for use as a potted plant and is the result of an ongoing breeding program to produce new and improved garden worthy plants for the ornamental market. The new plant was the result of open-pollinated seed collected by the inventor in fall of 2010 at a cultivated landscape in Raleigh, N.C., USA using P×WC 04-02 (not patented) as the seed or female parent. The male or pollen parent is unknown, but may have been any one of a number of hybrids or cultivars in the breeding area.

No plants of Lagerstroemia ‘Cherry Mocha’ have been sold, in this country or anywhere in the world, prior to the filing of this application, nor has any disclosure of the new plant been made prior to the filing of this application with the exception of that which may have been disclosed within one year of the filing of this application and was either derived directly or indirectly from the inventor.

Lagerstroemia ‘Cherry Mocha’ was initially asexually propagated by stem cuttings at a wholesale perennial nursery in Zeeland, Mich., USA in 2012. The resultant plants from successive generations have demonstrated that the new plant has remained stable and true to type in multiple generations of asexual propagation.

SUMMARY OF THE INVENTION

Plants of the new cultivar ‘Cherry Mocha’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with changes in light, temperature, soil and available moisture and fertility without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘Cherry Mocha’. Among the characteristics in combination which distinguish ‘Cherry Mocha’ as a new and distinct cultivar, unique from all other cultivars known to the inventor are:

• • 1. Dense, compact, upright to slightly outright growth habit;
  • 2. Semi-glossy foliage emerges burgundy red and slowly matures to deep green with burgundy tinting;
  • 3. Burgundy-colored stems;
  • 4. Bright cherry-red flowers open from shiny red buds;
  • 5. Resistance to Cercospora leaf spot and Erisphe powdery mildew;
  • 6. Ground hardy to at least USDA hardiness zone 6.

‘Cherry Mocha’ is distinguished from its female parent, P×WC 04-02, with flowers that are more red and darker, burgundy-tinted foliage.

The most similar cultivars known to the inventor include: ‘PIILAG-III’ U.S. Plant Pat. No. 23,178, ‘Trured’ U.S. Plant Pat. No. 18,646 and ‘Whitt VII’ U.S. Plant Pat. No. 14,975. ‘Cherry Mocha’ is shorter and narrower than ‘PITLAG-III’ and has more purplish tinting in the flower. Flower color is very similar to ‘Trured’, but this comparison variety develops into a small tree and is much larger than the new plant. ‘Whitt VII’ is slightly larger in habit and has more grey in the flower color than the new plant.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the flower and foliage characteristics and the overall appearance of ‘Cherry Mocha’, showing the colors as true as it is reasonably possible to obtain in color 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 Lagerstroemia.

DETAILED BOTANICAL DESCRIPTION

The following color references are based on The 2001 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used.
