Origin & Breeding History: 'Art Boe' originated from an open pollinated cross made by Arthur A. Boe between the female parent 'Hetz Wintergreen' and pollen from an unknown male parent in 1998 in Faribault, Michigan, USA. The new variety was selected in 2001 in Faribault, Michigan based on winter hardiness, plant habit, growth rate and no leaf bronzing in the winter.

Tests & Trials: Trials 'Art Boe' were conducted in an outdoor irrigated container trial during the summer of 2009 in St. Thomas, Ontario. The trial included a total of 8 plants of the candidate variety and the reference variety. All plants were grown from 3.8 litre plants transplanted to 11.4 litre containers in the spring of 2009. Observations and measurements were taken on September 25, 2009. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
