Origin & Breeding History: 'Antong Two' originated from a naturally occurring branch mutation of a Hibiscus syriacus seedling. The new variety was discovered and selected by the breeder Dr. Shim Kyong-ku in 1995, in Andong Province, South Korea. It was selected based on flower colour, flower size, foliage colour and dwarf growth habit. The variety was first propagated by softwood cuttings and grafting in 1996, in Seoul, South Korea.
Tests & Trials: Trials were conducted as a container trial during the summer of 2007 in St. Thomas, Ontario. The trial included a total of 15 plants of the candidate variety and 8 plants of the reference variety. All plants were grown in 7.5 litre containers during the summer of 2007. Observations and measurements were taken from 2 year old plants, 10 plants or 10 parts of plants of each variety on July 31, 2007. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
