Origin & Breeding History: 'Ross' (breeder's reference 'FK 4471') was developed by the breeder, Ike Vlielander at the FGB B.V. Research Facility, De Lier, The Netherlands. It originated from a cross between the female parent 'Leonardo' and the male parent 'Tenorio', made in September 1999. The new kalanchoe variety was selected in 2001 based on flower colour and a unique double-decorative flower type.

Tests & Trials: The detailed description is based on the UPOV report of Technical Examination, CPVO reference number 2004/0093, application number KAL 684, grant number 16094, purchased from the CPVO, Angers, France. The trials were conducted by the Bundessortenamt in Hannover, Germany, in 2004. Colour determinations were made using the 2001 Royal Horticultural Society (RHS) colour chart.
