Origin & Breeding History: 'Leading Lady Orchid' originated from a cross conducted in the summer of 2012, in Zeeland, Michigan, USA. The cross was made between the female parent, an unreleased proprietary hybrid of Monarda didyma and Monarda bradburiana, and pollen from an unknown sibling of the cross. 'Leading Lady Orchid' was initially selected in the summer of 2014 for its growth habit, disease resistance, flower colour and performance. 'Leading Lady Orchid' was first propagated by stem cuttings in 2015.

Tests & Trials: The comparative trial for 'Leading Lady Orchid' was conducted outdoors under a galvanized steel structure covered with black mesh shade fabric during the summer of 2021 at Variety Rights Management in Oxford Station, Ontario. The trial included a total of 15 plants each of the candidate and reference variety. All plants were grown as 1 plant per 16 cm pot and the pots were spaced 40 cm apart. Observations and measurements were taken from 10 plants, or parts of plants, of the candidate and reference variety. All colour determinations were made using the 2015 Royal Horticultural Society (RHS) Colour Chart.
