Origin & Breeding History: 'Rendia' was discovered and developed by the breeder, Jean Renault, in Gorron, France. It was discovered in 2007 as a whole plant mutation of an unnamed proprietary seedling. 'Rendia' was selected in 2007 for its panicles of flowers that emerge white and mature to red at the end of summer, early colour change of the inflorescences, compact and mounding plant growth habit, fertile flowers with large sepals, and reddish brown stem colour. 'Rendia' was first asexually propagated by softwood cuttings in May 2007, in Gorron, France.

Tests & Trials: The detailed description of 'Rendia' is based on the UPOV report of Technical Examination, application number 2011/0927, 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 2013. The colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
