„Anthesis begins between 1700 and 1800 h, and at thistime the flowers emit a perfumed, strong and sweetish odour, which is perceived at long distances. The odour is emitted mainly by the bract. The flowers are protandrous and last for 6 to 7 d (each phase lasts for 3 d, but the malestage sometimes lasted 4 d).“

The pleasent scent of the flowers seemed to be oscillating from one main note to another, floral or fruity, watery and spicy. From a headspace trapped sample, 83 constituents could be identified. It turned out that (E)-ocimene (53.9%), linalool (7.0%), dihydro-β-ionone (0.1%), β-ionone (0.3%), anethole (1.3%), (Z,Z)-deca-4,7-dienol (0.2%), γ-decalactone, and methyl (E)-3-methyldec-4-enoate (0.2%) were of special olfactory importance.
