The study aim was to observe the flowering process by descriptive observational method. The results showed that the flowers bloomed at 42 to 43 days after shooting (DAS), the scent smell began wafted at 32 to 43 DAS, and the length time of blooming flowers was 10-21 days long. The length time of flowering set was 29-30 days after the appearance of flower buds. Flowering process include three phases: Shoots, flower buds and bloom. Sharp tip shoots appear on the stem nodes and growth horizontally forming an angle 90⸰ to stem. The flower bud shapes were right-angled triangle and bow.
