Origin & Breeding History: 'Warm Yoigloo' was developed by the breeder, Mr. Mark A. Smith, an employee of Yoder Brothers, Inc. in Barberton, Ohio, USA. It originated from a cross pollination made in Salinas, California, USA, in December 2000 between a Chrysanthemum seedling with white decorative flowers designated '95-L464005' as the female parent and Chrysanthemum variety 'Mei Kyo' as the male parent. 'Warm Yoigloo' was selected in October 2001 in Alva, Florida, USA based on its early (natural season) flowering time, uniform plant growth habit, desirable inflorescence form, inflorescence size and floret colour. Asexual reproduction of 'Warm Yoigloo' by vegetative tip cuttings was first conducted in Alva, Florida, USA in January 2002.
Tests & Trials: Trials for 'Warm Yoigloo' were conducted outdoors during the summer of 2007 at BioFlora Inc. in St. Thomas, Ontario. Twenty liners of each variety were transplanted into 20 cm pots on June 7, 2007. The plants were grown outdoors with drip irrigation, in rows spaced 50 cm apart. Observations and measurements were taken from 10 plants of each variety on August 30. Flower characteristics were observed at full flower on October 18 & 25. All colour determinations were made using the 2001 Royal Horticulture Society (RHS) Colour Chart.
