The leaf blades of 'Carpiswi' are divided, whereas those of 'Sunmarisakura' are not. The main colour of the upper side of the corolla of 'Carpiswi' is strongly fading to almost white with age, whereas it is darker and weakly fading in 'Verena', and moderately fading in 'Sunmarisakura'.

Origin & Breeding History: 'Carpiswi' was developed in Enkhuizen, The Netherlands, by the breeder Har Stemkens, an employee of Syngenta Seeds B.V. The new variety originated from a cross made in August 1999 in Enkhuizen, between the female parent 'Z0924-3' and the male parent 'Z0637-2'. A plant was selected from the resulting progeny in May 2001, based on criteria for early flowering, flower colour and plant habit. The variety has been propagated asexually through vegetative cuttings since June 2001.

Tests & Trials: The tests and trials for 'Carpiswi' were conducted in a polyhouse during the spring and summer of 2006, at BioFlora Inc. in St. Thomas, Ontario. The trial included 15 plants of each variety. Rooted cuttings were transplanted into 10 cm pots on April 18, 2006. Observations and measurements were taken from 10 plants of each variety on June 17 to 19, 2006. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
