plant named ‘IRODORI’

Abstract

A new and distinct Loropetalum cultivar named ‘IRODORI’ is disclosed, characterized by bright pink, white, green and maroon variegated foliage, tall upright and spread habit and bright pink flowers with some flower re-bloom after the initial heavy Spring bloom. The new variety is a Loropetalum, normally produced as an outdoor garden or container plant.

Description

Latin name of the genus and species: Loropetalum chinense.

Variety denomination: ‘IRODORI’.

BACKGROUND OF THE INVENTION

The new Loropetalum cultivar is a product of a planned breeding program conducted by the inventor, Yuji Suzuki, in Kawaguchi City, Saitama, Japan. The objective of the breeding program was to produce new Loropetalum varieties with better foliage color and improved flowering for ornamental commercial applications. The cross resulting in this new variety was made during Apr. 24, 2004.

The seed parent is the, unpatented, commercial variety referred to as Loropetalum ‘Kinsai’. The pollen parent is the unpatented, propriety variety referred to as Loropetalum ‘3-28’. The new variety was discovered in a commercial nursery by the inventor in a group of seedlings resulting from the 2004 crossing, in Kawaguchi City, Saitama, Japan.

Asexual reproduction of the new cultivar was performed by softwood cuttings. This was first performed at a commercial nursery in Kawaguchi City, Saitama, Japan, in 2009 and has shown that the unique features of this cultivar are stable and reproduced true to type in 5 successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘IRODORI’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘IRODORI’ These characteristics in combination distinguish ‘IRODORI’ as a new and distinct Loropetalum cultivar:

• • 1. Bright and well variegated foliage with pink, white, slight undertones of green and maroon colors.
  • 2. Tall, upright and spreading plant, reaching 4 to 6 feet tall.
  • 3. Stunning bright pink flower that complement the variegated foliage.
  • 4. Some re-bloom occurs after the initial heavy Spring flowering.

Plants of the new cultivar ‘IRODORI’ are similar to plants of the seed parent, Loropetalum ‘Kinsai’ in most horticultural characteristics, however, plants of the new cultivar ‘IRODORI’ differ in the following;

• • 1. Bright red/pink flowers. The seed parent flower color is red.
  • 2. Upright and outwardly spreading growth habit. The seed parent growth habit is only upright.
  • 3. Foliage shape is broad ovate. The parent foliage shape is ovate.
  • 4. Brighter foliage variegation of pink, white, green and maroon. The seed parent foliage color is more subdued and only white, scarlet and purple.

Plants of the new cultivar ‘IRODORI’ are similar to plants of the pollen parent, Loropetalum ‘3-28’ in most horticultural characteristics, however, plants of the new cultivar ‘IRODORI’ differ in the following;

• • 1. Bright red/pink flowers; the pollen parent flower color is scarlet.
  • 2. Upright and spreading growth habit; the pollen parent growth habit is only spreading.
  • 3. Back of leaf color is a lighter shade of green.
  • 4. Brighter foliage variegation of pink, white, green and maroon; the parent pollen parent is only variegated with white.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘IRODORI’ are comparable to the patented, commercial variety Loropetalum ‘Shang-hi’ U.S. Plant Pat. No. 18,331. The two Loropetalum varieties are similar in most horticultural characteristics; however, the new variety ‘IRODORI’ differs in the following:

• • 1. Upright and somewhat open, free branching growth habit. The comparator growth habit is upright and more densely branched.
  • 2. Bright foliage variegation of pink, white, green and maroon. The comparator foliage is solid dark purple.
  • 3. Degree of variegation changes throughout the season becoming most prominent in late Summer and Fall. The comparator holds same color all season.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘IRODORI’ grown in a 1 gallon pot. Age of the plant photographed is approximately 1 to 2 years old from a rooted cutting.

FIG. 2 illustrates the foliage, around July 2014.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
