plant named ‘PIILC-IV’

Abstract

A new and distinctive cultivar of Loropetalum named ‘PIILC-IV’ that is characterized by its compact, mounded, spreading growth habit, its foliage that is dark purple in color that changes to green in color summer through winter, its flowers that are red-purple in color, and its good cold hardiness with hardiness at least in U.S.D.A. Zones 7 to 9.

Description

Botanical classification: Loropetalum chinense var. rubrum.

Variety denomination: ‘PIILC-IV’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Loropetalum chinense var. rubrum and will be referred to hereafter by its cultivar name, ‘PIILC-IV’. ‘PIILC-IV’ is an evergreen shrub grown for use as an ornamental landscape plant.

‘PIILC-IV’ originated as a seedling from seed derived from open pollination of Loropetalum chinense var. rubrum ‘GriffCRL’ (U.S. Plant Pat. No. 16,615). The male parentage is therefore unknown. The Inventor selected ‘PIILC-IV’ as a single unique plant in the summer of 2012 from amongst the resulting seedlings.

Asexual propagation of the new cultivar was first accomplished by one of the Inventors using semi-hardwood cuttings in Watkinsville, Ga. in 2013. Asexual propagation by semi-hardwood cuttings has determined that the characteristics of this cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘PIILC-IV’ as a unique cultivar of Loropetalum.

• • 1. ‘PIILC-IV’ exhibits a compact, mounded, spreading growth habit.
  • 2. ‘PIILC-IV’ exhibits foliage that is dark purple in color that changes to green in color summer through winter.
  • 3. ‘PIILC-IV’ exhibits flowers that are red-purple in color.
  • 4. ‘PIILC-IV’ exhibits good cold hardiness and is cold hardy at least in U.S.D.A. Zones 7 to 9.

The female parent of ‘GriffCRL’, ‘PIILC-IV’, differs from ‘PIILC-IV’ in having a rounded plant habit, a multi-stem trunk, a taller mature height of over 3.6 m, flowers that are vibrant fuchsia in color, immature and mature foliage that is grey-purple in color. ‘PIILC-IV’ can also be compared to Loropetalum chinense var. rubrum cultivars ‘PIILC-IV’ (U.S. Plant Pat. No. 25,470) and ‘PIILC-III’ (U.S. Plant Pat. No. 25,471). ‘PIILC-II’ differs from ‘PIILC-IV’ in having foliage that is ruby red in color maturing to purplish green, and flowers that are red-pink in color. ‘PIILC-III’ differs from ‘PIILC-IV’ in having foliage that is dark purple in color persistently year around, and flowers that are dark pink in color.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Lorepetalum. The photographs were taken of a four year-old plant of ‘PIIIP-I’ as grown in the ground in Watkinsville, Ga.

The photograph in FIG. 1 provides a side-view of the plant habit of in bloom.

The photograph in FIG. 2 provides a close-up view of a flower of ‘PIIIP-I’.

The photograph in FIG. 3 provides a close-up view of the spring and early summer foliage of ‘PIIIP-I’.

The photograph in FIG. 4 provides a view of the foliage color as it turns color in summer of ‘PIIIP-I’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the Detailed Botanical Description accurately describe the colors of the new Lorepetalum.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of four year-old plants of the new cultivar as grown in the ground in sun in Watkinsville, Ga. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
