'Sunsenebaibai' has weaker anthocyanin colouration of the petiole and a weaker degree of lobing of the leaf blades than both reference varieties. The flowers of 'Sunsenebaibai' are smaller in diameter than those of both reference varieties. The main colour on the upper side of the ray florets of 'Sunsenebaibai' is blue violet with violet in the area of transition to the secondary colour while it is blue violet for 'Senetti Blue Bicolor' and violet but redder for 'Sunsenereba'.

Origin & Breeding History: 'Sunsenebaibai' originated from a cross made in January 1995 between the female parent, a breeding line designated 'BW131', and the male parent, a seedling of Senecio heritieri. The cross was conducted in Hokuto-shi, Yamanashi, Japan. The resultant seedlings were grown in pots in a glasshouse and evaluated. In February 2004, 'Sunsenebaibai' was selected based on its plant growth habit, flower size and flower colour. It was later propagated by cuttings and grown in pots in Hokuto-shi, Yamanashi, Japan where it was subjected to trials starting in July 2005.

Tests & Trials: Trials for 'Sunsenebaibai' were conducted in a polyhouse during the winter and spring of 2008 at BioFlora Inc. in St. Thomas, Ontario. The trial included 15 plants per variety. The plants were grown from rooted cuttings which were transplanted into 15 cm pots on March 19, 2008. The plants were provided a natural cold treatment for approximately 5 weeks at 10°C until flower buds were visible and then grown further at 18°C. Measured characteristics were based on measurements taken from 10 plants or parts of plants on May 27, 2008. All colour determinations were made using the 2001 Royal Horticulture Society (RHS) Colour Chart.
