Origin & Breeding History: 'Scrivjean' originated as the result of a cross between 'Noatraum' as the female parent and 'Shine On' as the male parent. The cross was conducted in June 1995 in Kidderminster, England with the resulting variety selected in June 1996. Selection criteria included growth habit, attractive glossy foliage, flower colour and form, few thorns and good disease resistance. Asexual reproduction by budding and cuttings was first carried out in 1997 in Kidderminster, England.

Tests & Trials: Test and trials were conducted in the field during the summer of 2009, in St. Thomas, Ontario. The trial included 8 plants each of the candidate and reference varieties. Rooted plants were transplanted to the field in May 2007 spaced 60 cm apart, with rows 90 cm apart. All observations and measurements were taken on plants on September 23, 2009. All colour measurements were made using the 2001 Royal Horticultural Society colour chart.
