Origin & Breeding History: 'Coast to Coast' resulted from a cross using the line crossing breeding method conducted in June 1998 at Valparaiso, Indiana, USA. The female parent was the variety 'Manhattan' and the male parent was the variety 'Golden Gate'. 'Coast to Coast' was selected in 2010 for its foliage colour, plant growth habit, plant size, and foliage texture. 'Coast to Coast' is primarily propagated asexually using plant divisions.

Tests & Trials: The comparative trial for 'Coast to Coast' was conducted in a polyhouse during the spring of 2015 at Variety Rights Management in Oxford Station, Ontario. There were 20 plants of both the candidate variety and the reference variety. Each plant was grown in a 16 cm diameter pot with 20 cm spacing between the pots. Observations and measurements were taken from 10 plants or parts of plants of each variety. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
