The margins of the corolla lobes are moderately undulating. The corolla tube is violet with moderately conspicuous veins. Before pollen dehiscence the anthers are medium blue.

Origin & Breeding History: The variety 'Suncopablue' originated from the crossing of a variety called 'Fantasy Blue' as the female parent and 'PAB2' as the male parent. The crossing was conducted at the Omi R&D Centre, Suntory Flowers Limited, in July 2000. In April 2001, 80 seedlings were obtained from that crossing. These seedlings were grown in pots in glasshouses and were evaluated. In September 2001, one seedling was selected in view of its growth habit, flower size and colour. That seedling was propagated by cuttings and a trial was carried out to examine the botanical characteristics of the selection. The new variety was named 'Suncopablue'.

Tests & Trials: Tests and trials for 'Suncopablue' were conducted in a polyhouse during the spring and summer of 2005 in St. Thomas, Ontario. The trials included a total of 15 plants of each variety. All plants were grown from rooted cuttings, planted into 15 cm pots on April 29, 2005. Observations and measurements were taken from 10 plants of each variety on June 14, 2005. All colour measurements were made using the RHS Colour Chart 2001.
