Origin & Breeding History: 'Synpin Henfirst' originated from a naturally occurring whole plant mutation of the variety 'Yohenry the First'. The new variety was discovered and developed by the breeder Mark Smith in April 2008 in Alva, Florida, USA. 'Synpin Henfirst' was selected based on flower colour and plant growth habit.

Tests & Trials: Trials for 'Synpin Henfirst' were conducted in an outdoor irrigated trial during the summer of 2010 in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate and reference varieties. All plants were grown from a single rooted cutting transplanted into a 20 cm standard pot on June 29, 2010. Observations and measurements were taken from 10 plants of the candidate variety on September 23, 2010, 'Synhen Thefirst' on September 14, 2010 and 'Victoria Celeste' on October 6, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
