Description

Latin name of the genus and species of the plant claimed: Chrysanthemum×morifolium.

Varietal denomination: ‘Syndurango Dark’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Chrysanthemum, botanically known as Chrysanthemum×morifolium, and hereinafter referred to by the variety name ‘Syndurango Dark’.

‘Syndurango Dark’ is a product of a planned breeding program. The new cultivar has large, dark greyed-orange ray florets, good floriferousness, strong straight stems, and dark foliage.

‘Syndurango Dark’ originates as a natural whole plant mutation of ‘Yodurango’, U.S. Plant Pat. No. 19,736. ‘Syndurango Dark’ was discovered and selected by the inventor as a single flowering plant within a population of the parent cultivar in a controlled breeding program in Fort Myers, Fla. in February, 2007. The parent cultivar ‘Yodurango’ has larger foliage, slightly shorter plant habit, ray florets that are a lighter color and wider in width, and is one half to one day faster in flowering response.

The first act of asexual reproduction of ‘Syndurango Dark’ was accomplished when vegetative cuttings were propagated from the initial selection in May 2007 in a controlled environment in Fort Myers, Fla.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in May 2007, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Syndurango Dark’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘Syndurango Dark’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length.

A Plant Breeder's Right for this cultivar was applied for in CVPO on Sep. 4, 2009 (#2009-1681). ‘Syndurango Dark’ has not been made publicly available more than one year prior to the filing of this application.

The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Chrysanthemum as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical inflorescence and foliage characteristics of ‘Syndurango Dark’ with colors being as true as possible with an illustration of this type. The photographic drawing shows four flowering potted plants of the new variety and a close-up of the inflorencenses.

 DETAILED BOTANICAL DESCRIPTION

The plant descriptions, measurements and aforementioned photographs were taken in the first week of May 2010 in Gilroy, Calif. under natural light. These plants were started and grown in Nipomo, Calif. and were brought to Gilroy in the first week of May 2010. Plants were grown under conditions which approximate those generally used in commercial potted mum production. These plants used were approximately 10 weeks old.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.) 2001.
