The new variety was discovered and selected by the breeder in December 2003, in Alva, Florida, USA. The selection of this variety was based on its early natural season flowering time, uniform plant growth habit, inflorescence form, inflorescence size and floret colour. Asexual reproduction by vegetative tip cuttings was first conducted in Alva, Florida, USA in February 2004.

Tests & Trials: Trials for 'Sunny Yoigloo' were conducted outdoors during the summer of 2008 in St. Thomas, Ontario. The trial consisted of a total of 15 plants per variety. All plants were grown from liners (cuttings were stuck on June 2, 2008). Observations and measurements were taken from 10 plants of each variety on September 15, 2008. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
