Abstract

A new and distinct cultivar of Loropetalum chinense var. rubrum plant named ‘PIILC-III’, characterized by its compact, mounded, spreading growth habit; dark purple foliage color that persists through summer and winter; dark 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-III’.
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-III’. 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 ‘GriffCRL’ (U.S. Plant Pat. No. 16,615) 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-III’ originated and was discovered in a cultivated environment in an outdoor nursery in Watkinsville, Ga.
‘PIILC-III’ has been asexually reproduced by softwood cuttings since 2009 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-III’ 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-III’ from all other varieties in commerce known to the inventor.
    • 1) Compact, mounded, spreading growth habit.
    • 2) Dark purple foliage color that persists through summer and winter.
    • 3) Dark pink flowers in spring.
    • 4) Improved cold hardiness compared to other compact purple-leaf cultivars.
‘PIILC-III’ is distinguished from its female parent ‘GriffCRL’ by its growth habit foliage color, and flower color. ‘PIILC-III’ has a compact mounded, spreading growth habit reaching 107 cm high×213 cm wide after 4½ years, whereas ‘GriffCRL’ has an overall larger, rounded growth habit reaching approximately 274 to 335 cm high and wide in the same amount of time. ‘PIILC-III’ has dark purple foliage that persists through summer and winter, whereas ‘GriffCRL’ has duller red-purple foliage that will become greenish purple in summer and winter. ‘PIILC-III’ has dark pink flowers, whereas ‘GriffCRL’ has light pink flowers. There are no other cultivars of Loropetalum chinense var. rubrum with this combination of traits known to the inventor.
‘PIILC-III’ can be compared to the cultivar ‘PIILC-I’ (U.S. Plant patent application Ser. No. 13/694,190), but differs in foliage and flower color. ‘PIILC-III’ has dark purple foliage, whereas ‘PIILC-I’ has rich reddish purple foliage. ‘PIILC-III’ has dark pink flowers, whereas ‘PIILC-I’ has bright pink flowers.
‘PIILC-III’ can be compared to the cultivar ‘Peack’ (U.S. Plant Pat. No. 18,441), but differs in growth habit, overall size, vigor, and hardiness. ‘PIILC-III’ has a compact mounded, spreading growth habit reaching 107 cm×213 cm after 4½ years, whereas ‘Peack’ has a mounding and weeping habit reaching 46 cm×92 cm after 3 years. ‘PIILC-III’ is more vigorous than ‘Peack’. ‘PIILC-III’ has exhibited increased cold hardiness compared to ‘Peack’ in Zone 7.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying illustrations show characteristics of the new cultivar in photographs as true to color as is reasonably possible to make in illustrations of this nature. 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 Loropetalum.
FIG. 1 illustrates the growth habit of a ‘PIILC-III’ plant growing in a container.
FIG. 2 illustrates a close-up of the foliage of ‘PIILC-III’.
FIG. 3 illustrates a close-up of the flowers of ‘PIILC-III’
