Title: Lagerstroemia plant named ‘Perky Pink’

Description:
Botanical classification:  Lagerstroemia  (L.) hybrid. 
     Variety denomination: ‘Perky Pink’. 
     STATEMENT REGARDING PRIOR DISCLOSURES UNDER 37 CFR 1.77(B)(6) 
     The first public disclosure of the claimed plant, in the form of a photograph and brief description on a website operated by Walters Gardens, Inc. was on Feb. 1, 2019. Subsequently, on May 29, 2019 Walters Gardens, Inc. advertised the new plant in the “Walters Gardens 19-20 Catalog” and by the first sale on Apr. 17, 2019. Walters Gardens, Inc. obtained the plant and all information relating thereto, from the inventor. No plants of  Lagerstroemia  ‘Perky Pink’ have been sold in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior to the filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor. 
     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 ‘Perky Pink’ or the “new plant.” ‘Perky Pink’ 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 plant market. The new plant was the result of open-pollinated seed collected by the inventor in fall of 2012 in a trial garden facility at a wholesale perennial nursery in Zeeland, Mich., USA using the proprietary, unreleased, unnamed hybrid known only by the breeder code H10-08-01 (not patented) as the seed or female parent. The male or pollen parent is a sibling of H10-08-01 (not patented). The new plant was given the breeder code 12-29-6. 
       Lagerstroemia  ‘Perky Pink’ was initially asexually propagated by stem cuttings at a wholesale perennial nursery in Zeeland, Mich., USA in 2014. The resultant plants from successive generations have demonstrated that the new plant has remained stable and true to type in multiple and successive generations of asexual propagation. 
     SUMMARY OF THE INVENTION 
     Plants of the new cultivar ‘Perky Pink’ 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 ‘Perky Pink’. Among the characteristics in combination which distinguish ‘Perky Pink’ as a new and distinct cultivar, unique from all other cultivars known to the inventor are:
         1. Dense, mounded growth habit;   2. Matte foliage emerges mahogany-colored and matures to dark olive-green;   3. Lower stems are striated, reddish-brown and tan-colored with upper stems reddish;   4. Pink flowers in dense panicles open on new growth to cover the shrub;   5. Resistance to  Cercospora  leaf spot and  Erisphe  powdery mildew;   6. Ground hardy to at least USDA hardiness zone 6.       

     The most similar cultivars known to the inventor include: ‘Chaff Berry’ U.S. Plant patent application Ser. No. 16/350,860, ‘Dark Roast’ U.S. Plant patent application Ser. No. 16/350,861 and the copending U.S. Plant patent application Ser. No. 16/873,023 ‘Peppermint Mocha’. ‘Dark Roast’ is shorter in habit and the flowers are a different hue of bright fuchsia pink. ‘Chai Berry’ is slightly taller and more upright in habit and the flowers are a different hue of rose-pink. ‘Peppermint Mocha’ has a shorter slightly more spreading habit and the flowers are a more rosy-pink. The female parent H10-08-01 has flowers are a more lavender coloration. Comparison with the male parent is not possible since the male parent was not maintained. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
       The accompanying color photographs illustrate the flower and foliage characteristics and the overall appearance of a seven-year-old plant of ‘Perky Pink’, growing in a full-sun trial garden in Zeeland, Mich., 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 2015 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used. The following observations and size descriptions are of approximately seven-year-old plants grown in a loamy-sand, full-sun, open trial bed in Zeeland, Mich., USA with supplemental water and fertilizer as needed. The phenotype may vary slightly with different environmental conditions, such as temperature, light, fertility, moisture and maturity levels, but without any change in the genotype.
