Description

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

Varietal denomination: ‘Bronze Yochatham’.

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 ‘Bronze Yochatham’.

‘Bronze Yochatham’ is a product of a planned breeding program. The new cultivar has medium sized, greyed-orange ray florets, good floriferousness, compact and easily controlled uniform habit with excellent branching, and dark foliage.

‘Bronze Yochatham’ originates as a natural whole plant mutation of ‘Yochatham,’ U.S. Plant Pat. No. 17,927. ‘Bronze Yochatham’ was discovered and selected by the inventor as a single flowering plant within a population of the parent cultivar grown outdoors in a field covered by saran in Fort Myers, Fla., in March 2005. The parent cultivar ‘Yochatham’ has light purple floret color. ‘Yochatham’ has a taller plant habit, smaller foliage size, and more ray florets than ‘Bronze Yochatham’.

The first act of asexual reproduction of ‘Bronze Yochatham’ was accomplished when vegetative cuttings were propagated from the initial selection in March 2005 in a controlled environment in Fort Myers, Fla.

A Plant Breeder's Right for this cultivar was applied for in Canada in October 2008. ‘Bronze Yochatham’ has not been made publicly available more than one year prior to the filing of this application.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in March 2005, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Bronze Yochatham’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘Bronze Yochatham’ 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.

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 flower and foliage characteristics of ‘Bronze Yochatham’ 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 growing in a five inch pot, and a close-up of the flowers.

 DETAILED BOTANICAL DESCRIPTION

The plant descriptions, measurements and aforementioned photographs were taken in Gilroy, Calif. in April 2009 under greenhouse conditions. These plants were started and grown in central coastal California, then shipped to Gilroy, Calif. in April 2009. Plants were grown under conditions which approximate those generally used in commercial potted chrysanthemum production and were about 9 weeks of age. Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.) 2001.
