Origin & Breeding History: 'MIPEHR436' originated from a cross pollination conducted in August 2015 in Nagaizumicho, Shizuoka, Japan. The cross was made between two unpatented proprietary breeding selections coded 'P27-271-1', as the female parent, and 'P27-655-1', as the male parent. From the resulting progeny, the new variety 'MIPEHR436' was discovered and selected as a single flowering plant in August of 2016 based on its plant growth habit, flower colour and garden performance. Asexual propagation of the variety was first conducted through in vitro meristem culture in August 2017.

Tests & Trials: The detailed description of 'MIPEHR436' is based on the UPOV report of Technical Examination, application number 33137, purchased from the Plant Variety Protection Office of the Ministry of Agriculture, Forestry and Fisheries in Japan. The trials were conducted by the Nishi-Nihon Station in Ibaraki, Japan in 2020. Colour determinations were made using the 2015 Royal Horticultural Society (RHS) Colour Chart.
