Patent Document

Genus and species of plant claimed:  Lagerstroemia indica×L. fauriei.    
     Variety denomination: ‘PIILAG B2’. 
     BACKGROUND OF THE INVENTION 
     The present invention relates to a new and distinct cultivar of  Lagerstroemia  plant, botanically known as  Lagerstroemia indica×L. fauriei , commonly known as crapemyrtle, and hereinafter referred to by the cultivar name ‘PIILAG B2’. ‘PIILAG B2’ is grown primarily as an ornamental for landscape use and for use as a potted plant. 
     ‘PIILAG B2’ originated from open-pollinated seed of  Lagerstroemia indica×L. fauriei  ‘Gamad VI’ (U.S. Plant Pat. No. 22,161) growing in Watkinsville, Ga. The cultivar ‘PIILAG B2’ originated in 2008 and was selected in a cultivated environment in Watkinsville, Ga. from the progeny of this open-pollination by continued evaluation for growth habit and foliage and flower characteristics. 
     Asexual reproduction of ‘PIILAG B2’ by stem cuttings in Watkinsville, Ga. since 2009 has shown that all the unique features of this new  Lagerstroemia , as herein described, are stable and reproduced true-to-type through successive generations of such asexual propagation. 
     SUMMARY OF THE INVENTION 
     Plants of the new cultivar ‘PIILAG B2’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with changes in light, temperature, soil and rainfall without, however, any variance in genotype. 
     The following traits have been repeatedly observed and are determined to be unique characteristics of ‘PIILAG B2’. These characteristics in combination distinguish ‘PIILAG B2’ as a new and distinct cultivar: 1. Compact, rounded intermediate growth habit; 2. Reddish purple new growth; 3. Cupped, lustrous dark green foliage in summer; 4. Clear pink flowers; 5. Resistance to powdery mildew and  Cercospora  leaf spot. 
     Plants of ‘PIILAG B2’ differ from plants of the parent, ‘Gamad VI’, primarily in growth habit, foliage, flower color, and time of flowering. Plants of ‘Gamad VI’ have a compact, mounded growth habit, flattened foliage, and produce deep red and purple flowers in early summer, whereas plants of ‘PIILAG B2’ have an overall larger, compact, rounded intermediate growth habit, cupped foliage, and clear pink flowers in mid-summer. 
     Plants of ‘PIILAG B2’ can be compared to the cultivar ‘Gamad V’ (U.S. Plant Pat. No. 17,411), but differ in overall size, foliage color, and flower color. Plants of ‘PIILAG B2’ have a compact, rounded intermediate growth habit, foliage that emerges reddish purple, and clear pink flowers, whereas plants of ‘Gamad V’ have an overall smaller, dwarf growth habit, medium green new growth, and lighter pink flowers.
