This study was performed to investigate the most suitable environment conditions of Hepatica asiatica on the position, vegetation, weather and soil conditions around Hepatica asiatica habitats. The survey location were selected at the Anilsa and Daeducksa temple areas of Mt. Daeduck and Pukjijangsa temple area of Mt. Palgong located in Taegu, Korea. Vertical distribution area of Hepatica asiatica was ranged from 200m to 500m above the sea level. Most of the habitats faced toward the north and the gradient was about 30 degree. Total species at all the survey locations were 38 woody plants and 56 herbaceous plants. 98.4 % of total woody plants was deciduous broad leaved tree. Dominant species was Indigofera kirilowii and Lespedeza maximowiczii var. tomentella at the Anilsa temple area, Stephanandra incisa and Lindera erythrocarpa at the Daeducksa temple area and Lespedeza maximowiczii and Viburnum punctatum at the Pukjijangsa temple area. Monthly average air temperature was ranged -5deg C - 5deg C in winter, 18deg C - 24deg C in summer and 10deg C - 15deg C in spring and autumn. Light intensity in the growing place of habitat was 10,000lux from Nov. to March, 4,000lux from Apr. to May and 1,200lux from June to September. Soil acidity at the survey location was pH 5.1 - 5.3. Total nitrogen contents, organic matter, P2O5, K, Ca, Mg, Na and CEC were 0.07 %, 21.1 %, 38ppm, 0.83m.e/100g, 8.1m.e/100g, 3.8m.e/100g, 0.56m.e/100g and 20.4m.e/100g, respectively. Soil texture was sandy loam and average soil moisture content was 23.3 % in March and 50.2 % in July
