Abstract

A distinct cultivar of Chrysanthemum plant named ‘Empire Riviera’, characterized by its uniformly mounded and relatively compact plant habit; uniform flowering; daisy-type inflorescences that are about 4.1 cm in diameter; attractive rose pink ray florets and bright yellow disc florets; and numerous inflorescences per plant.

Description

BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Dendranthema grandiflora and referred to by the cultivar name Empire Riviera.
The new cultivar is a product of a planned breeding program conducted by the Inventor in New York Mills, N.Y. The objective of the breeding program is to create new garden-type Chrysanthemum cultivars having inflorescences with desirable inflorescence forms and floret colors and good garden performance.
The new cultivar originated from a cross made by the Inventor in October, 1993 of two unidentified proprietary seedling selections.
The cultivar Empire Riviera was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in New York Mills, N.Y., in September, 1994. The selection of this plant was based on its desirable inflorescence form and ray floret color.
Asexual reproduction of the new cultivar by terminal cuttings taken in a controlled environment in New York Mills, N.Y., has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar Empire Riviera has 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 ‘Empire Riviera’. The characteristics in combination distinguish ‘Empire Riviera’ as a new and distinct cultivar:
1. Uniformly mounded and relatively compact plant habit.
2. Uniform flowering.
3. Daisy-type inflorescences that are about 4.1 cm in diameter.
4. Attractive rose pink ray florets and bright yellow disc florets.
5. Numerous inflorescences per plant.
The new Chrysanthemum is similar to the Chrysanthemum cultivar Kimberly (disclosed in U.S. Plant Pat. No. 9,026). However in side-by-side comparisons under commercial practice, plants of the new Chrysanthemum differed from plants of the cultivar Kimberly in the following characteristics:
1. Plants of the new Chrysanthemum flower about five days earlier than plants of the cultivar Kimberly.
2. Plants of the new Chrysanthemum have more ray florets per inflorescence than plants of the cultivar Kimberly.
3. Ray florets of plants of the new Chrysanthemum are darker in color than ray florets of plants of the cultivar Kimberly.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new cultivar.
The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Empire Riviera’.
The photograph at the bottom of the sheet comprises a close-up view of typical inflorescences of the cultivar ‘Empire Riviera’. These photographs show the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Floret and foliage colors in the photographs may differ from the actual colors due to light reflectance.
DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown in Leamington, Ontario, Canada, under conditions which approximate those generally used in commercial garden Chrysanthemum production. One rooted cutting was planted in a 15-cm container on July 20, 1998 and plants were grown outdoors under natural season conditions. Measurements and numerical values represent averages for typical flowering containers.
