USPP36276P2 - Cuphea plant named ‘DCUPCUBSID’ - Google Patents

Abstract

A new and distinct Cuphea plant named ‘DCUPCUBSID’ is disclosed, characterized by being sterile with a moderately vigorous habit, and a long flowering period. The plant has dark-green foliage with red-orange and cream-green colored flowers. The new variety is a Cuphea, normally produced as an outdoor garden or container plant.

Description

Latin name of the genus and species: Cuphea hybrida.

Variety denomination: ‘DCUPCUBSID’.

BACKGROUND OF THE INVENTION

The new Cuphea plant 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 Cuphea varieties. The cross resulting in this new variety was made during the summer of 2018.

The seed parent is the unpatented, propriety variety referred to as Cuphea micropetala ‘CPB-17-7010’. The pollen parent is the unpatented, propriety variety referred to as Cuphea ignea ‘CPB-15-3101’. The new variety was discovered in May of 2019 by the inventor in a group of seedlings resulting from the parental crossing, in a greenhouse in Moshav Mishmar Hashiva, Israel.

Asexual reproduction of the new cultivar ‘DCUPCUBSID’ was first performed by terminal vegetative cuttings during May of 2019, at a greenhouse in Moshav Mishmar Hashiva, Israel. Subsequent propagation by terminal vegetative cuttings has shown that the unique features of this cultivar are stable and reproduced true to type in successive generations. First public access to plants of the variety occurred Dec. 25, 2022 in Italy. This offer came directly or indirectly from the inventor, qualifying for the exception allowed under 102(b). Previous to this sale, although the variety may have been publicized in print, plants were not available to the public for propagation.

SUMMARY OF THE INVENTION

The cultivar ‘DCUPCUBSID’ 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 ‘DCUPCUBSID’ These characteristics in combination distinguish ‘DCUPCUBSID’ as a new and distinct Cuphea cultivar:

• • 1. Sterile plants.
  • 2. Dark green foliage.
  • 3. Red-orange and cream-green flower color.
  • 4. Moderately vigorous habit.
  • 5. Long flowering period.

PARENT COMPARISONS

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

• • 1. Plants of the new variety are sterile, while plants of the seed parent are fertile.
  • 2. Plants of the new variety produce more flowers than plants of the seed parent.
  • 3. Plants of the new cultivar have a different floral tube color and size.
  • 4. Foliage of the new variety is smaller than foliage of the seed parent.
  • 5. Plants of the new variety produce more branches than plants of the seed parent.

Plants of the new cultivar ‘DCUPCUBSID’ are similar to plants of the pollen parent in most horticultural characteristics however, plants of the new cultivar ‘DCUPCUBSID’ differ in the following;

• • 1. Plants of the new variety are sterile, while plants of the pollen parent are fertile.
  • 2. Plants of the new variety have a different floral tube color and size.
  • 3. Plants of the new variety have more vigorous, upright habits than plants of the pollen parent.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘DCUPCUBSID’ can be compared to the commercial variety Cuphea ‘David Varity’, unpatented. These varieties are similar in most horticultural characteristics; however, ‘DCUPCUBSID’ differs in the following:

• • 1. Plants of the new variety are shorter than plants of this comparator.
  • 2. Plants of the new variety produce more flowers than plants of this comparator.
  • 3. Foliage of the new variety is less sensitive to cold than foliage of this comparator.
