Abstract:
A new and distinct cultivar of  Loropetalum chinense  var.  rubrum  plant named ‘PIILC-II’, characterized by its compact, mounded, spreading growth habit; rich ruby-red new growth maturing to purplish green foliage that persists through summer and winter; bright reddish pink flowers in spring; and improved cold hardiness compared to other compact purple-leaf cultivars.

Description:
Genus and species of plant claimed:  Loropetalum chinense  var.  rubrum.    
     Variety denomination: ‘PIILC-II’. 
     BACKGROUND OF THE INVENTION 
     The present invention relates to a new and distinct cultivar of  Loropetalum chinense  var.  rubrum , a member of the Hamamelidaceae family, hereinafter referred to by its cultivar name ‘PIILC-II’. This cultivar is grown primarily as an ornamental for landscape use and for use as a potted plant. 
     The cultivar originated from an open-pollination of  Loropetalum chinense  var.  rubrum  ‘Chang Nian Hong’ (not patented) in Watkinsville, Ga. in 2008, and was selected from the progeny seedlings of this open-pollination by continued evaluation for growth habit and improved foliage characteristics. The cultivar ‘PIILC-II’ originated and was discovered in a cultivated environment in an outdoor nursery in Watkinsville, Ga. 
     ‘PIILC-II’ has been asexually reproduced by softwood cuttings since 2009 in Athens, Ga. and in Watkinsville, Ga. The characteristics of the cultivar have been stable and reproduced true to type in successive vegetative generations. 
     SUMMARY OF THE INVENTION 
     ‘PIILC-II’ has 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 observed and represent the characteristics of the new cultivar. In combination these characteristics distinguish ‘PIILC-II’ from all other varieties in commerce known to the inventor. 1) Compact, mounded, spreading growth habit. 2) Rich ruby-red new growth maturing to purplish green foliage that persists through summer and winter. 3) Bright reddish pink flowers in spring. 4) Improved cold hardiness compared to other compact purple-leaf cultivars. 
     ‘PIILC-II’ is distinguished from its female parent ‘Chang Nian Hong’ by its growth habit and foliage color. ‘PIILC-II’ has a compact mounded, spreading growth habit reaching only 170 cm high×224 cm wide after about 4 years, whereas ‘Chang Nian Hong’ has an overall larger, rounded growth habit. ‘PIILC-II’ has rich, ruby-red new growth maturing to purplish green foliage that persists through summer and winter, whereas ‘Chang Nian Hong’ has duller red-purple foliage that will become greenish purple due to stress in summer and winter. There are no other cultivars of  Loropetalum chinense  var.  rubrum  with this combination of traits known to the inventor. 
     ‘PIILC-II’ can be compared to the cultivar ‘Shang-hi’ (U.S. Plant Pat. No. 18,331) but is distinguished by its growth habit, foliage color, and flower color. ‘Shang-hi’ has a dense, upright, globose habit, dark purple foliage, and dark pink flowers, whereas ‘PIILC-II’ has a compact, mounded, spreading growth habit, rich ruby-red new growth maturing to purplish green foliage, and bright reddish pink flowers.
