plant named ‘Renaissance Eden’

Abstract

A new and distinct cultivar of Begonia plant named ‘Renaissance Eden’, characterized by its upright and mounded plant habit; freely branching habit; leaves with finely-serrated margins; large and showy frilled double flowers with numerous tepals that are yellow and orange in color and are held above and beyond the foliar plane; and excellent postproduction longevity.

Description

Botanical designation: Begonia×hiemalis.

Cultivar denomination: ‘RENAISSANCE EDEN’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begonia plant, botanically known as Begonia×hiemalis, commercially known as Elatior Begonia and hereinafter referred to by the name ‘Renaissance Eden’.

The new Begonia plant is a naturally-occurring branch mutation of Begonia×hiemalis ‘Renaissance Chloris’, not patented. The new Begonia was discovered and selected by the Inventor on a single flowering plant within a population of plants of ‘Renaissance Chloris’ in a controlled greenhouse environment in Aichi, Japan in March, 2007.

Asexual reproduction of the new Begonia plant by vegetative cuttings taken in a controlled greenhouse environment in Aichi, Japan since August, 2007, has shown that the unique features of this new Begonia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Begonia have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength 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 ‘Renaissance Eden’. These characteristics in combination distinguish ‘Renaissance Eden’ as a new and distinct Begonia plant:

• • 1. Upright and mounded plant habit.
  • 2. Freely branching habit.
  • 3. Leaves with finely-serrated margins.
  • 4. Large and showy frilled double flowers with numerous tepals that are yellow and orange in color and are held above and beyond the foliar plane.
  • 5. Excellent postproduction longevity.

Plants of the new Begonia differ primarily from plants of the parent, ‘Renaissance Chloris’, in flower color as plants of ‘Renaissance Chloris’ have orange-colored flowers. In addition, plants of the new Begonia have larger flowers than plants of ‘Renaissance Chloris’.

Plants of the new Begonia can be compared to plants of Begonia ×hiemalis ‘Renaissance Flora’, not patented. In side-by-side comparisons conducted in Aichi, Japan, plants of the new Begonia differed primarily from plants of ‘Renaissance Flora’ in the following characteristics:

• • 1. Plants of the new Begonia were taller than plants of ‘Renaissance Flora’.
  • 2. Plants of the new Begonia had larger flowers than plants of ‘Renaissance Flora’.
  • 3. Plants of the new Begonia and ‘Renaissance Flora’ differed in flower color as plants of ‘Renaissance Flora’ had orange red-colored flowers.
  • 4. Plants of the new Begonia had longer peduncles and pedicels than plants of ‘Renaissance Flora’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Begonia 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 accurately describe the colors of the new Begonia plant.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Renaissance Eden’ grown in a container.

The photograph at the bottom of the sheet is a close up view of a typical plant of ‘Renaissance Eden’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the winter in Aichi, Japan, under commercial practice in 15-cm containers in a polyethylene-covered greenhouse. During the production of the plants, the day temperatures ranged from 10° C. to 35° C. and the night temperatures ranged from 15° C. to 25° C. Plants were eight months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
