Origin & Breeding History: 'Minall2' originated from a cross-pollination conducted in May 2008 as part of a controlled breeding program in La Menitre, Maine-et-Loire, France, between a proprietary breeding selection designated '11078', as the female parent, and the variety 'Mindia' (Coppertina), as the male parent. From the resulting progeny, 'Minall2' was discovered and initially selected in August 2011 for its immature and mature foliage colour, and moderately vigorous, compact and upright plant growth habit.
Tests & Trials: The detailed description of 'Minall2' is based on the UPOV report of Technical Examination, application number 2014/1502, purchased from the Community Plant Variety Office, in Angers, France. The trials were conducted by the National Institute of Agricultural Botany in Cambridge, United Kingdom, in 2015 and 2016. The colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
