Kew Garden 一共有四個開放植物溫室，其中三個有規模的，一個是非常小的小池塘養荷花。從Vitoria Gate大門進入Kew Gardenu右轉沒多遠就到第一溫室"Palm Hourse"。在1844年和1848年之間建造的。婀娜的外觀和熱氣騰騰的空氣，Palm house內部早就作出一個圖標的花園。官方網站報導有"The Palm House has 16,000 panes of glass"，相當驚人。主要展示亞熱帶植物如非洲，印度和東南亞的植物。其實有許多在台灣是常見到的植物，但在此溫帶的國家，這些植物就很稀奇了，包括我們常見到"日日春"
以下是Kew Garden 網站的介紹。http://www.kew.org/visit-kew-gardens/garden-attractions-A-Z/Palm-House.htm
"Highlights in the South Wing, which contains plants from Africa and the Indian Ocean Islands, include the African oil palm (Elaeis guineensis) the most important oil-producing plantation palm in the Tropics and the rare triangle palm (Dypsis decaryi) from Madagascar. The main central section houses plants from the Americas, including many economically important species. You’ll find cocoa, rubber, banana and papaya plants growing here alongside the Mexican yam (Dioscorea macrostachya) which was used to develop the contraceptive pill. The North Wing showcases plants from Asia, Australasia and the Pacific, the region that contains the world’s greatest diversity of palms. Here you’ll find climbing palms called rattans from which cane furniture is made. Also, there are several Asian fruit trees including mango, starfruit, breadfruit and jackfruit."
