From the resulting progeny, 'Agrihydrazestien' was selected on April 25, 2009, in Glandorf, Germany, for its "mop-head" type inflorescence, inflorescence colour, and vigorous plant growth. 'Agrihydrazestien' was first asexually propagated by cuttings on April 20, 2010, in Glandorf, Germany.
Tests & Trials: The detailed description of 'Agrihydrazestien' is based on the UPOV report of Technical Examination, application number 2009/2617, 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 2011 to 2012. The colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
