Loropetalum plant named ‘Peack’

Abstract

A new and distinct variety of Loropetalum that possesses unique color and growth habit.

Description

Latin name: Loropetalum chinensis.

Variety denomination: ‘Peack’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of Loropetalum chinensis, which was discovered as an unusual, distinctive, and ornamentally special seedling of unpatented Loropetalum chinensis ‘Pizzazz™’ at a commercial greenhouse located close to Loxley, Ala., by James Bryan Berry in 2002. The unique characteristics of the new variety ‘Peack’ will make the plant useful when used as a groundcover in the landscape in appropriate USDA climactic zones. The plant is unlike the species in growth habit.

Loropetalum chinensis ‘Peack’ has been asexually reproduced for four generations by cutting and has demonstrated stability of growth of all phenotypic characteristics from the original plant thru each generation. Asexual reproduction was achieved at a commercial greenhouse in Loxley, Ala. by James Bryan Berry. ‘Peack’ also has been reproduced by tissue culture in a laboratory in Magnolia, Tex. Thru this propagation process the variety ‘Peack’ has been reliably stable and true to type for several generations. Both methods of propagation resulted in identical plants to the original ‘Peack’ plant.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

Color references are made to The Royal Horticulture Society Colour Chart (1995 Edition) and all terminology used is from this color chart. Otherwise descriptive terminology is botanic or ordinary in nature. Plants grown in #1 containers were used for the following descriptions. Plants were grown under normal greenhouse commercial conditions near Magnolia, Tex. The observed plants were 14 months old from date of planting. During the production period day temperatures ranged from 29 to 37 degrees Celsius and night temperatures ranged from 25 to 27 degrees Celsius. Characteristics of plants observed in growing at a commercial nursery near Loxley, Ala. were identical to the plants described. This botanic description was made in November 2005.

Comparison with Parent

Loropetalum chinensis ‘Peack’ is unique in growth habit. A four-year-old plant is naturally 1.5 feet tall and 36 inches wide without pruning or shaping. The plant is strongly mounding with branches sharply turning outward and then downward. The parent variety Loropetalum chinensis ‘Pizzazz™’ is not compact but is an upright growing shrub to about 12 feet high and 7 feet wide.

‘Peack’ is distinctive to another known cultivars because the underside of the leaf is a deep violet. The parent Loropetalum chinensis ‘Pizzazz™’ as well as ‘Bill Wallace’, U.S. Plant Pat. No. 15,277 all have leaves with undersides that are green. Additionally, the average leaf of the new plant is 50% + wider than the comparative varieties, excluding ‘Zhuzhou’.

Comparison to Comparable Cultivars

The following traits are determined to be the unique characteristics of ‘Peack’. The traits which cause ‘Peack’ to be a new and distinct cultivar are:

• • 1. Significantly larger leaf width than the species average
  • 2. Deep, violet (non-green) pigmentation of underside of leaf
  • 3. A mounding and spreading growth habit

In side-by-side comparisons, plants of the new Loropetalum chinensis ‘Peack’ differed from plants of the cultivar ‘Bill Wallace’ in the following ways:

• • 1. Plants of the new cultivar ‘Peack’ are mounding compared to ‘Bill Wallace’ which is outwardly spreading with prostate plant growth.
  • 2. Leaves of the new cultivar ‘Peack’ are large and wide compared to the leaves of ‘Bill Wallace’, which are narrow and small.
  • 3. The underneath side of the leaves of ‘Peack’ are deep violet and the underneath sides of the leaves of ‘Bill Wallace’ are green.

In side-by-side comparisons, plants of the new Loropetalum chinensis ‘Peack’ differed from the non-patented parent cultivar, ‘Pizzazz™’ in the following ways:

• • 1. Plants of the new cultivar ‘Peack’ are mounding compared to ‘Pizzazz™’, which grows strongly upright.
  • 2. Leaves of the new cultivar ‘Peack’ are larger and wider compared to the leaves of ‘Pizzazz™’, which are narrower and not as long.
  • 3. The underneath side of the leaves of ‘Peack’ are deep violet and the underneath sides of the leaves of ‘Pizzazz™’ are green.

In side-by-side comparisons, plants of the new Loropetalum chinensis ‘Peack’ differed from the cultivar, ‘Zhuzhou’ in the following way:

• • 1. Plants of the new cultivar ‘Peack’ are mounding compared to ‘Zhuzhou’, which grows strongly upright.

SUMMARY OF THE INVENTION

Loropetalum chinensis ‘Peack’ has a unique combination of characteristics. ‘Peack’ has unusually dark colored foliage, large leaves, and a mounding and spreading growth habit. ‘Peack’ attributes make it an ideal candidate for landscape use as an intermediate groundcover.
