USPP27181P3 - Coreopsis plant named ‘DCOREO202’ - Google Patents

Abstract

A new and distinct Coreopsis cultivar named ‘DCOREO202’ is disclosed, characterized by long, continuous flowering on highly floriferous plants. Large flowers of intense color, mounded plant habit and good branching creating a dense and full body. The new variety is a Coreopsis, normally produced as an outdoor garden or container plant.

Description

Latin name of the genus and species: Coreopsis cordata.

Variety denomination: ‘DCOREO202’.

BACKGROUND OF THE INVENTION

The new Coreopsis cultivar is a product of a planned breeding program conducted by the inventor, Gavriel Danziger, in Moshav Mishmar Hashiva, Israel. The objective of the breeding program was to produce new Coreopsis varieties for ornamental commercial applications. The open pollination resulting in this new variety was made during June of 2010.

The seed parent is the unpatented, proprietary seedling variety referred to as Coreopsis cordata ‘co-z-41’ The pollen parent is unknown as it was an open pollination breeding program. The new variety was discovered in July of 2011 by the inventor in a group of seedlings resulting from the 2010 open pollination, in a research greenhouse in Moshav Mishmar Hashiva, Israel.

Asexual reproduction of the new cultivar was performed by vegetative cuttings. This was first performed at a research greenhouse in Moshav Mishmar Hashiva, Israel during December of 2010 and has shown that the unique features of this cultivar are stable and reproduced true to type in more than 30 successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘DCOREO202’ 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 ‘DCOREO202’ These characteristics in combination distinguish ‘DCOREO202’ as a new and distinct Coreopsis cultivar:

• • 1. Good branching—dense and full bodied plant.
  • 2. Large flowers with intense color.
  • 3. Long & continuous flowering period.
  • 4. Mounded habit.
  • 5. Highly floriferous—many flowers are fully open at the same time.

Plants of the new cultivar ‘DCOREO202’ are similar to plants of the seed parent, Coreopsis cordata ‘co-z-41’ in most horticultural characteristics, however, plants of the new cultivar ‘DCOREO202’ differs in the following:

• • 1. Fuller and denser plant structure.
  • 2. More abundant flowering.
  • 3. Shorter in height.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘DCOREO202’ are comparable to the commercial variety Coreopsis ‘Limbo’ U.S. Plant Pat. No. 22,130. The two Coreopsis varieties are similar in most horticultural characteristics; however, the new variety ‘DCOREO202’ differs in the following:

• • 1. Fuller and denser plant structure.
  • 2. More abundant flowering.
  • 3. Wider leaf.
  • 4. ‘DCOREO202’ has bi-color red and yellow flowers compared to creamy white flowers of ‘Limbo’.
  • 5. Shorter in height.

Plants of the new cultivar ‘DCOREO202’ are also comparable to the commercial variety Coreopsis ‘Mambo’ U.S. Plant Pat. No. 22,131. The two Coreopsis varieties are similar in most horticultural characteristics; however, the new variety ‘DCOREO202’ differs in the following ways:

• • 1. Fuller and denser plant structure.
  • 2. More abundance flowering.
  • 3 ‘DCOREO202’ has bi-color red and yellow flowers compared to bi-color dark pink and light pink flowers of ‘Mambo’.
  • 4. Shorter in height

BRIEF DESCRIPTION OF THE PHOTOGRAPHS
