Title: Chrysanthemum plant named ‘Yogigi Snow’

Description:
Latin name of the genus and species of the plant claimed:  Chrysanthemum×morifolium.    
     Varietal denomination: ‘Yogigi Snow’. 
     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 ‘Yogigi Snow.’ 
     ‘Yogigi Snow’ is a product of a planned breeding program. The new cultivar has small white flowers with strong stiff plants, short, compact and mounded plant habit with a natural flowering season about the middle of September. 
     ‘Yogigi Snow’ originates as a natural whole plant mutation of ‘Yogigi White,’ U.S. Plant Pat. No. 20,435, and 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 Alva, Fla., in April 2007. The parent cultivar ‘Yogigi White’ has wider ray florets, shorter peduncles, and a couple days slower flowering response time. 
     The first act of asexual reproduction of ‘Yogigi Snow’ was accomplished when vegetative cuttings were propagated from the initial selection in April 2007 in a controlled environment in Alva, Fla. 
     BRIEF SUMMARY OF INVENTION 
     Horticultural examination of plants grown from cuttings of the plant initiated in April 2007, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Yogigi Snow’ are firmly fixed and are retained through successive generations of asexual reproduction. 
     ‘Yogigi Snow’ 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. 
     Plant Breeder&#39;s Rights for this cultivar were applied for in the European Union on Nov. 26, 2008 and in Canada on Oct. 30, 2009. ‘Yogigi Snow’ 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 flower and foliage characteristics of ‘Yogigi Snow’ with colors being as true as possible with an illustration of this type. The photographic drawing shows a flowering potted plant of the new variety, and a close-up of the flowers. 
     
    
    
     DETAILED BOTANICAL DESCRIPTION 
     The plant descriptions, measurements and aforementioned photographs were taken outdoors in Gilroy, Calif. in late October 2009. These plants were approximately 12-14 weeks of age. The plants were propagated in Alva, Fla., then shipped to California at about 3-4 weeks of age, potted up and set outdoors in a trial. 
     Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.) 2001.
