We investigated the blooming period and the morphology of the flowers in Camellia hiemalis for the plants grown under several controlled temperature conditions of the outdoor temperature altered by+4.5°C, +3.0°C, +1.5°C, ±0.0°C and -1.5°C. The results showed that the blooming period began earlier under cool conditions. There were a greater number of fruitful flowers under warmer conditions, with a greater number of petals and stamen, and longer pistils. Thus, the development of flower buds was encouraged but resulted in inhibited sprouting under warmer conditions. It was thought that the blooming period and morphology of the flowers of Camellia hiemalis should change under warmer conditions.
