This beautiful daylily combines Ontario hybridizer Brian Culver's 'Inspiration Road' with one of my best introductions 'Lavender Space Journey'. I am very pleased with the outcome.  The result is a beautiful purple bitone flower with lighter lilac sepals. It also has a soft lemon yellow applique throat. There is very good 4-5 way branching on the scapes and an average of 18 buds per scape.  The flowers begin in midseason and mature clumps have an outstanding display with the contrasting bitone colours. It is a full sibling to my 2020 introduction 'Pink Triangle'. For naming the plant, there actually is such a thing as a bitonal symphony, and a quick google search gives an adequate explanation. However, my use of the name 'Bitonal Symphony' also employs a secondary meaning for bitonal, that being two shades of the same colour. Since the flower is registered as a bitone (dark petals and lighter sepals in the same colour range)  I thought 'Bitonal Symphony' was appropriate even if it is a bit of play on words.         Double Fan (DF) $55.
