Avicennia marina is the most widely distributed mangrove species in Taiwan. It has early mature seeds and seedlings. The hypocotyles can germinate and grow in 3 weeks after the fruit growth, yet the seed dispersal occurs 6-7 weeks after the fruit growth.

海茄苳具有早熟的種子與早熟的幼苗,果實內胚軸發育3週後即可發芽生長,但是種子則於6~7週後才自然掉落,所以稱之為「隱藏性胎生」。幼苗發育8~9個月即可開花,抽芽展葉全年都在進行,北臺灣冬季較寒冷,抽芽展葉較少,南臺灣於早春大量抽芽展葉。開花期於南臺灣(北緯23° 27’44.2”~22° 27’39.5”)幾乎同步於5月中旬至7月中旬,果實成熟期於8月至9月,果落期為8月至9月中旬;北臺灣(北緯24° 54’45.7”~24° 54’33.0”)則約晚2週,北臺灣之開花結實率遠低於南臺灣。海茄苳的花具有香
