長春花 madagascar rosy periwinkle / old maid (catharanthus roseus)

長春花有個有趣的英文俗名 – old maid老姑娘。名字印證了植物長年開花,太日常親切。大家其實都忽略她的美好。

native to madagascar, madagascar rosy periwinkles are also known as old maid. i believe it is because they are so common around the world in the warm areas and they flower and fruit whole year round.

你有認真欣賞過長春花嗎?紫粉紅如扇面的五塊花瓣,均勻大方。花筒結構別致,圓筒,喉部緊縮。雌雄蕊藏於花管內,所以採長春花都是有長舌的蛾和蝶。

i recommend you pay close attention to this lovely plant. immediately you will found it is no common lady.

the flowers are deep pink or white, comprising five petals spreading from a long, tubular throat. interestingly the pistil and stamen are all hiding inside the tube. the plant only entertains moths and butterflies with long tongue, as it has the ability to self-pollinate too.

其果,另有趣味。蓇葖雙生,直立,有條紋。

the fruit also has its character, made up of two narrow, cylindrical follicles which house many grooved seeds.

長春花原生馬達加斯加,現廣生於世界各地的溫暖地區。

平實是寶。上世紀醫學上一大突破,是發現長春花中可提取化學物質作治癌之用。

the plant has ‘superpower’ too. it is known as the source of chemical compounds now used in the treatment of cancer.
