USPP32501P2 - Trachelospermum plant named ‘TRARED’ - Google Patents

Abstract

A new and distinct Trachelospermum hybrid named ‘TRARED’ is disclosed, characterized by distinctive red Fall and Winter foliage, and a dense plant form. Plants flower abundantly and produce elliptic, glossy foliage. The new cultivar is a Trachelospermum typically suited for ornamental container and landscape use.

Description

Latin name of the genus and species: Trachelospermum jasminoides.

Variety denomination: ‘TRARED’.

BACKGROUND OF THE INVENTION

The new cultivar is the result of chance discovery in France. The new variety was discovered as a naturally occurring whole plant mutation of an unnamed, unpatented Trachelospermum jasminoides. The new variety was discovered in February of 2011 at a commercial nursery in Saint Cyr en Val, France.

After selecting and isolating the new cultivar, asexual reproduction of the new cultivar ‘TRARED’ was first performed in Saint Cyr en Val, France, by terminal vegetative cuttings in July 2011. The inventor isolated the interesting new plant and continued confidential testing for stability over time. Since July of 2011 ‘TRARED’ has since produced multiple generations, and has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘TRARED’ 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 ‘TRARED’. These characteristics in combination distinguish ‘TRARED’ as a new and distinct Trachelospermum cultivar:

• • 1. Unique red foliage color beginning in Fall and continuing through Winter
  • 2. Abundant flowering.
  • 3. Narrower foliage.
  • 4. Glossy foliage.
  • 5. Smaller mature plant size.

PARENTAL COMPARISON

The new variety is similar to the parent in most horticultural characteristics, however plants of the new variety differ in the following:

• • 1. Foliage color of the new variety is red in the Winter and Spring, whereas the parent variety has green and brown Winter foliage.
  • 2. Plants of the new variety are observed evergreen, plants of the parent variety are somewhat deciduous comparatively.
  • 3. Plants of the new variety flower more abundantly than plants of the parent variety.
  • 4. Foliage of the new variety is narrower and glossier than foliage of the parent variety.
  • 5. Mature plant size of the new variety is smaller than mature plants of the parent variety.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘TRARED’ are similar to the commercial variety Trachelospermum ‘Rose’ unpatented, in most horticultural characteristics. However, the new variety differs from ‘Rose’ in the following:

• • 1. Foliage color of the new variety is red in the Winter and Spring, whereas this comparator has green Winter Foliage.
  • 2. Flowers of the new variety are white, flowers of this comparator are pink.
  • 3. Plants of the new variety flower more abundantly than plants of ‘Rose’.
  • 4. Foliage of the new variety is narrower and glossier than foliage of ‘Rose’.
  • 5. Mature plant size of the new variety is smaller than mature plants of ‘Rose’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘TRARED’ grown outdoors in France at approximately 8 months of age.

FIG. 2 is a comparison photograph of the new variety and the parent variety. ‘TRARED’ is on the left of the photograph, the parent variety is on the right.
