In an attempt to obtain the basic data for the development of Hanabusaya asiatica as horticultural plants, studies were conducted on the habitat environment, ecological characteristics, various treatments for breaking seed dormancy, and morphological and flowering characteristics of H. asiatica at different growth stages. Hanabusaya asiatica was distributed around areas of 850–1400 m above sea level with an inclination of 5–43°. The vegetation structure of H. asiatica was represented in groups as Quercus mongolica and H. asiatica. In a subgroup, Symplocos chinensis v. leucocarpa for. pilosa, Magnolia sieboldii, and Acer mono were included. Indication species of Quercus mongolica and H. asiatica were Quercus mongolica (B1 layer), Tilia amurensis (B2 layer), Rhododendron schlippenbachii (S layer), Ainsliaea acerifolia v. subapoda, Athyrium nipponicum, Spuriopimpinella brachycarpa, and Carex siderostica (K layer). Soil pH was about 5.4, and soil fertility was relatively in a good condition. The optimum conditions for seed germination was at 25Y.
