今年加州的厄爾尼諾天氣讓俺家後院早春二月的花牆到三月初才形成，不過花的密度比往年有增無減，花香也越來越濃鬱。
說起茉莉花，想必大家都會想到那清香無比的白色小花，茉莉花茶更是人們再熟悉不過的了。自古國人就特別喜愛茉莉花，寫茉莉花的名詩更是無數。宋代詩人江奎更是將茉莉列為花王。
一般來講，茉莉花分為大花茉莉和小花茉莉兩類，大花茉莉包括摩洛哥茉莉（Jaminum officinale）印度茉莉（Jasminum grandiflorum），但如果從植物學上來講大花茉莉應該單指Jasminum officinale var. grandiflorum藥用茉莉大花變種（也稱印度茉莉）。
小花茉莉隻是相對大花茉莉的一個稱呼，其實它的花並不小。她的學名是：Jasminumsambac，一般翻譯為阿拉伯茉莉（以前有看到把她翻譯成印度茉莉的，那是錯的喲，可別搞混了，要看拉丁文的喲！）
有很多人會看到不同品牌的茉莉，中文名字有很多，如：摩洛哥茉莉，法國茉莉，印度茉莉，埃及茉莉，阿拉伯茉莉，估計一般人肯定暈了。其實最重要的就是看拉丁文和植物產地。
茉莉是公主型的植物，需要全神貫注的照顧才行。非常挑剔土壤，否則茉莉雖然不少開花，但香氣並不濃。
大花茉莉的味道與我們平時喝的茉莉花茶味道有著極大的區別。大花茉莉中含有高量的“吲哚”成份，是非常珍貴的成份喲！相比之下，小花茉莉也就是阿爾伯茉莉的味道就好聞多了，是雖然也是強烈的花香，但清純，淡雅了很多，帶著青綠的幽香，仿佛月光下的仙子（就是我們熟悉的茉莉花茶香味）。
來美國之前，在上海和江南見到的都是小花茉莉。第一次見到大花茉莉是搬到現在的家的第二年早春，在後院的牆上，零星的幾叢，年複一年，花開花落，到今年的春天已是一片茂密的花牆了。。。
謝謝觀貼！
原來中文名字叫多花素馨。多花素馨（學名：Jasminum polyanthum）是木犀科素馨屬的植物，是中國的特有植物。分布在中國大陸的雲南、貴州、四川等地，生長於海拔1,400米至3,000米的地區，一般生於灌叢、山穀及疏林，目前尚未由人工引種栽培。別名:素興花, 雞爪花、狗牙花（雲南）。多謝彩煙遊士！
Jasminum polyanthum, also known as Pink Jasmine (or White Jasmine), is an evergreen twining climber native to China and Burma (Myanmar). It produces an abundance of reddish-pink flower buds in late winter and early spring, followed by fragrant five-petalled star-like white flowers which are about 2 cm in diameter. It has compound leaves with 5 to 7 leaflets which are dark green on the upper surface and a lighter green on the lower surface. The terminal leaflet is noticeably larger than the other leaflets. The plant is very vigorous and can grow up to 6 metres in height when supported. Depending on the climate, this vine has a semi-deciduous to evergreen foliage.
Jasminum polyanthum is well known as a house plant in the USA and Europe. It can also grow in the garden, when climate conditions are good. USDA hardiness zones: 8 - 11. It grows fast and easily, and flowers nicely. Outside it can be used to cover walls and fences etc. It can grow in sun and light shade as well. It is propagated by seed and by suckers. Jasminum polyanthum was given the Award of Garden Merit (AGM) by the RHS in 1993. It was chosen on the Bicentenary list of 200 plants for the RHS: “This popular houseplant is an easily-grown, evergreen, half-hardy climber with loose panicles in summer of many strongly-fragrant pink-backed, white, trumpet-shaped flowers. It does not suffer pest or disease problems and is simple to propagate.
不過我覺得這是不是大花茉莉，而是粉茉莉（pink jasmine），學名Jasminum polyanthum，一種入侵性極強的外來物種。
