Origin & Breeding History: 'Avantgarde' was bred and developed by the breeder, Niels Arts, in Aalsmeer, Netherlands. It originated from a cross conducted on May 15, 2007, in De Kwakel, Netherlands, between the female parent designated '206255-01', and the male parent designated '2020611-01'. From the resulting progeny, 'Avantgarde' was selected on April 25, 2009, in Glandorf, Germany, for its inflorescence size and production without vernalisation, and overall plant growth habit. 'Avantgarde' was first asexually propagated by cuttings on April 20, 2010, in Glandorf, Germany.

Tests & Trials: The detailed description of 'Avantgarde' is based on the UPOV report of Technical Examination, application number 2008/1171, purchased from the Community Plant Variety Office, in Angers, France. The trial was conducted by the Groupe d'Étude et de contrôle des Variétés Et des Semences, in Brion, France, from 2009 to 2010. The colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
