USPP36439P2 - Lippia nodiflora plant named ‘ECOLOPIA 4’ - Google Patents

Abstract

A new and distinct cultivar of Lippia plant named ‘ECOLOPIA 4’ is disclosed, characterized by uniquely long internodes, about 2.6 cm, resulting in tall plants. Plants of the new variety grow vigorously to about 160 cm wide in 3 months and 2 cm tall. The new variety has excellent tolerance for heat, humidity and disease. Foliage is larger than average, plants are sterile. The new variety is a Lippia, useful for a variety of horticultural purposes.

Description

Latin name of the genus and species: Lippia nodiflora.

Variety denomination: ‘ECOLOPIA 4’.

BACKGROUND OF THE INVENTION

The new Lippia cultivar is a product of chance discovery by the inventor, Masataka Ohde, in Oyama, Japan. The new variety was discovered as a naturally occurring single plant mutation in a greenhouse in Oyama, Japan.

The parent is an unnamed, unpatented variety of Lippia nodiflora. The new variety was discovered June 2021 by the inventor in a group of plants of the parent variety.

Asexual reproduction of the new cultivar ‘ECOLOPIA 4’ was first performed at a commercial greenhouse in Oyama, Japan by terminal vegetative cuttings during July 2021. More than 3 generations have been reproduced by vegetative cuttings. Subsequently, propagation has also shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘ECOLOPIA 4’ 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 ‘ECOLOPIA 4’. These characteristics in combination distinguish ‘ECOLOPIA 4’ as a new and distinct Lippia cultivar:

• • 1. Long internode of about 2.6 cm.
  • 2. Tolerance to disease.
  • 3. Tolerance to high humidity.
  • 4. Above average foliage size.
  • 5. Variety is sterile.
  • 6. Rapid growth.

PARENT COMPARISON

Plants of the new cultivar ‘ECOLOPIA 4’ are similar to the parent variety in most horticultural characteristics. The new variety however differs in the following characteristics:

• • 1. Internodes of the new variety average 2.6 cm, internodes of the parent average 1.6 cm.
  • 2. The new variety is faster growing than the parent variety.
  • 3. Leaf length of the new variety is about 1.7 cm, leaf length of the parent is about 1.1cm.
  • 4. Peduncles of the new variety are about 4 cm; peduncles of the parent are about 2.1 cm.
  • 5. Leaf width of the new variety is about 0.9 cm, leaf width of the parent is about 0.8 cm.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘ECOLOPIA 4’ are similar to the commercial variety Lippia ‘Campagna Verde’ U.S. Plant Pat. No. 20,120 in most horticultural characteristics. The new variety however differs in the following characteristics:

• • 1. Shorter plant height, measured at foliar plane. ‘Campagna Verde’ grows to 3 cm, the new variety grows to 2 cm.
  • 2. Stronger tolerance to disease under high heat and high humidity conditions.
  • 3. Corolla color of ‘Campagna Verde’ is Violet-Blue 91D, corolla color of ‘ECOLOPIA 4’ is RHS Purple 75B.

‘ECOLOPIA 4’ can be compared to the commercial variety Lippia nodiflora ‘ECOLOPIA1’ U.S. Plant Pat. No. 27,036. Plants of ‘ECOLOPIA1’ are similar to plants of ‘ECOLOPIA 4’ in most horticultural characteristics. However, ‘ECOLOPIA 4’ differs from ‘ECOLOPIA1’ in the following characteristics:

• • 1. Internodes of the new variety average 2.6 cm, internodes of ‘ECOLOPIA1’ average 1.7 cm.
  • 2. Leaf length of the new variety is about 1.7 cm, leaf length of ‘ECOLOPIA1’ is about 1 cm.
  • 3. Peduncles of the new variety are about 4 cm, peduncles of ‘ECOLOPIA1’ are about 2.5 cm.
  • 4. Fully opened Corolla color of ‘ECOLOPIA1’ is RHS Violet-Blue 91D, corolla color of ‘ECOLOPIA 4’ is RHS Purple 75B.
