Flowering phenology data was analyzed qualitatively, while flower morphology character data was analyzed quantitatively. The results show that the flowering phenology of melati putih takes place in an average of 26 days with environmental factors being light intensity 337.00-2639.00 lux, air temperature 27-34oC, humidity 61-82%, and rainfall 0.0–9.6 mm. Air temperature and humidity influence the process of bud emergence and the length of time for large buds to develop towards anthesis.
