Origin & Breeding History: 'SHIMRV24' originated from a cross conducted by the breeder, Kyung-Ku Shim, in Suwon, South Korea. The cross was made in July 2002 between the Hibiscus syriacus variety 'Antong Two', as the female parent, and the Hibiscus variety 'Busae', as the male parent. From the resulting progeny, 'SHIMRV24' was selected in July 2008 based on its dwarf habit, flower colour and appearance and dark green foliage. 'SHIMRV24' was first asexually propagated by softwood cuttings and grafting in June 2009 in Suwon, South Korea.

Tests & Trials: The comparative trial of 'SHIMRV24' was conducted in an outdoor irrigated container trial during the spring and summer of 2018, at BioFlora Inc., in St. Thomas, Ontario. The trial included a total of 12 shrubs each of the candidate and reference variety. All shrubs were grown from 5.7 cm liners, planted into 9 litre containers on July 19, 2017. The plants were overwintered in an un-heated polyhouse. The observations and measurements were taken from 10 plants, or parts of plants, of each variety on July 11, 2018. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
