Origin & Breeding History: 'Curtina' originated from a controlled cross between the female parent proprietary seedling designated 1998248-03 and the male parent proprietary seedling designated 1998231-02. The cross was conducted by the breeder, Leonardus Johannes Maria van der Knaap, in De Lier, The Netherlands on May 23, 2001. The new variety was selected on June 2, 2004 based on flower colour, leaf colour and suitability to grow as pot plant. 'Curtina' was first propagated in-vitro on July 16, 2003 in Maasdijk, The Netherlands.

Tests & Trials: The detailed description of 'Curtina' is based on the UPOV report of Technical Examination, reference number 2004/1516, purchased from the Community Plant Variety Office, Angers, France. The trials were conducted by Naktuinbouw in Wageningen, The Netherlands, in 2005. Colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
