'Hanabell' is a new ornamental crabapple cultivar bred in 2020 at the Apple Research Institute, National Institute of Horticultural and Herbal Science, Rural Development Administration. It was selected from seedlings obtained through the open-pollination of Malus baccata collected from Mt. Palgong, Gunwi-gun, and Gyeongsangbuk-do. Line selections were conducted from 2009 to 2016, and characteristic tests were evaluated from 2017 to 2019. The tree vigor and form of 'Hanabell' were determined to be medium and spreading, respectively. The flowering season of 'Hanabell' starts on April 17th and ends on May 2nd, lasting approximately 15 days. The size of 'Hanabell' flowers is approximately 48 mm, larger than that of general apple flowers, and they have a high ornamental value due to the abundance of blooms each year. Furthermore, 'Hanabell' possesses a distinct floral scent that releases a significant amount of benzyl acetate (C9H10O2) into the air during flowering, attracting bees. Subsequently, 'Hanabell' was officially submitted for variety protection to the KoreaSeed & Variety Service in 2021(Applicationno.2021-144).
