Lilium longiflorum often called the Easter lily or November lily, is a plant native to the Ryukyu Islands (Japan) and Taiwan. It is a stem rooting lily, growing up to 1 m high. It bears a number of trumpet shaped, white, fragrant, and outward facing flowers. It is extensively cultivated for cut flowers. It has irregular blooming periods in nature, and this is exploited in cultivation, allowing it to be forced for flowering at particular periods, such as Easter. However, it can be induced to flower over a much wider period. This variety is sometimes called the Bermuda lily because it has been much cultivated in Bermuda. From the 1890s to the early 1920s, there was a thriving export trade of bulbs from Bermuda to New York. A disease affected the Bermuda lilies: this was identified by Lawrence Ogilvie. Then most Easter lily bulbs arriving in the United States were imported from Japan before 1940s. The supply of bulbs was suddenly cut off after the attack on Pearl Harbor and Easter lilies became extremely valuable in the United States.
The Easter lily is a rich source of steroidal glycosides, a group of compounds that may be responsible for some of the traditional medicinal uses of lilies.In Chinese Medicine, Bai he (the scales from tiger lily bulbs) is said to nourish lung yin, stop cough, clear heat and calm the spirit.
