plant named ‘CANRL01’

Abstract

A new and distinct Loropetalum plant named ‘CANRL01’ particularly distinguished by a compact, semi-prostrate growth habit, dark burgundy colored foliage that retains its color throughout the year, and medium, dark pink colored flowers, is disclosed.

Description

Genus and species: Loropetalum chinense.

Variety denomination: ‘CANRL01’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Loropetalum plant, botanically known as Loropetalum chinense, and hereinafter referred to by the variety name ‘CANRL01’. This new Loropetalum plant originated from an open pollination conducted in the spring of 2011 in Dearing, Ga. between the female Loropetalum plant ‘Chang Nian Hong’ (unpatented) and an unknown male Loropetalum plant. The objective of the breeding program was to create new, easier to grow Loropetalum plants having unique flower colors and with improved plant growth habits.

Progeny seeds resulting from said open pollination were collected in the fall of 2011. These seeds were sown in June of 2012 and allowed to grow. The new variety was selected by the inventor as a single plant within progeny plants grown in a controlled environment in Dearing, Ga. The new variety was selected based on its medium dark pink colored flowers and overall improved plant growth characteristics as compared to other commercially available Loropetalum cultivars. ‘CANRL01’ was first reproduced asexually by vegetative semi-softwood stem cuttings in July 2014 in Dearing, Ga. ‘CANRL01’ has been found to retain its distinctive characteristics and has been found to be stable and reproduce true-to-type through three successive generations of asexual reproduction by vegetative semi-softwood stem cuttings.

Plant Breeder's Rights for this variety have not been applied for. ‘CANRL01’ has not been made publicly available or sold anywhere in the world prior to the effective filing date of this application.

SUMMARY OF THE INVENTION

The new Loropetalum variety has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, light intensity, water status, fertilizer rate and type, without, however, any variance in genotype.

The following are the most outstanding and distinguishing characteristics of this new Loropetalum variety when grown under normal horticultural practices in Dearing, Ga. The combination of these characteristics distinguishes ‘CANRL01’ as a new and distinct variety of Loropetalum:

• • 1. Compact, semi-prostrate growth habit;
  • 2. Burgundy colored foliage that retains its color throughout the year; and
  • 3. Medium, dark pink flower color.

DESCRIPTION OF THE PHOTOGRAPHS

This new Loropetalum is illustrated by the accompanying photographs which show the overall plant habit including flowers and foliage of the plant. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of 2, 4 and 6-year-old plants grown in ground and in 2.5 inch and 3-gallon containers in Dearing, Ga. The photographs were taken in Dearing Ga. under natural light and natural shade. Colors in the photographs may differ slightly from the color values cited in the botanical description which accurately describes the colors of the new variety.

DESCRIPTION OF THE NEW VARIETY

In the following description, color references are made to The Royal Horticultural Society Colour Chart, Sixth Edition, except where general terms of ordinary dictionary significance are used.

The following observations and measurements describe plants grown outdoors under a natural photoperiod in full sun in Dearing, Ga. Some observations were made indoors under artificial lighting using the aid of a dissecting microscope. Detailed descriptions were taken from February 2018 through March 2021 from 4 and 6-year-old plants grown in ground and from 2-year-old plants grown in 3-gallon containers. Measurements and numerical values represent averages of typical plant types.

COMPARISON WITH PARENTAL VARIETIES

‘CANRL01’ differs from the female parent plant ‘Chang Nian Hong’ (unpatented) in that ‘CANRL01’ has a semi-prostrate growth habit and medium dark pink colored flowers, whereas ‘Chang Nian Hong’ has a mounding, more upright growth habit and larger, more dark burgundy colored foliage and darker red colored flowers.

COMPARISON WITH KNOWN CULTIVARS

When ‘CANRL01’ is compared to the commercial Loropetalum cultivar ‘Peack’ (U.S. Plant Pat. No. 18,441), ‘Peack’ has a more prostrate growth habit and lighter pink colored flowers and lighter burgundy colored foliage.
