Rose plant named ‘Evera 108’

Abstract

A new and distinct cultivar of rose plant named ‘Evera 108’, characterized by its upright, compact and rounded plant habit; dark green-colored leaves; large bright double yellow-colored flowers with numerous petals per flower; flowers held upright on strong and erect peduncles; and good postproduction longevity.

Description

Botanical designation: Rosa hybrida.

Cultivar denomination: ‘Evera 108’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of the Rose class, botanically known as Rosa hybrida, commercially known as a potted Rose and hereinafter referred to by the name ‘Evera 108’.

The new Rose plant is a product of a planned breeding program conducted by the Inventor in Denmark. The objective of the breeding program was to develop new potted Rose cultivars with novel and attractive flower colors, disease resistance and excellent postproduction longevity.

The new Rose plant originated from a cross-pollination made by the Inventor on Mar. 1, 2002 of two unnamed proprietary Rosa hybrida seedlings, not patented. The cultivar Evera 108 was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Denmark. Plants of the new cultivar differ primarily from plants of the parent selections primarily in flower color.

Asexual reproduction of the new Rose plant by cuttings in Denmark since Nov. 20, 2003, has shown that the unique features of this new Rose plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The new Rose plant has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature and light level, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Evera 108’. These characteristics in combination distinguish the new Rose plant as a new and distinct cultivar:

• • 1. Upright, compact and rounded plant habit.
  • 2. Dark green-colored leaves.
  • 3. Large double bright yellow-colored flowers with numerous petals per flower.
  • 4. Flowers held upright on strong and erect peduncles.
  • 5. Good postproduction longevity.

Plants of the new Rose plant can be compared to plants of the Rose cultivar Evera 116, disclosed in U.S. Plant Pat. No. 16,956. In side-by-side comparisons conducted in Denmark, plants of the new Rose differed from plants of the cultivar Evera 116 in the following characteristics:

• • 1. Flowers of plants of the new Rose had more petals per flower than flowers of plants of the cultivar Evera 116.
  • 2. Plants of the new Rose and the cultivar Evera 116 differed in flower coloration as plants of the cultivar Evera 116 had softer yellow-colored petals.

BRIEF DESCRIPTION OF PHOTOGRAPHS

The accompanying colored photographs illustrate typical specimens of the vegetative growth and flowers of the new Rose plant, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which more accurately describe the actual colors of the new Rose plant.
