Video by Champa lao. Dok Champa (Plumeria) is known as the national flower and official symbol of Laos.
Updated 2/24/2009: I also like this version of champa song, Noi Sengsourigna – Champa Meuang Lao.
According to Wikipedia, this flower has a different name depending on location, many other common names exist: “Kembang Kamboja” in Indonesia, “Temple Tree” or “Champa” in India, “Kalachuchi” in the Philippines, “Araliya” or “Pansal Mal” in Sri Lanka, “Champa” in Laos, “Lantom” or “Leelaawadee” in Thai. Many English speakers also simply use the generic name “plumeria”.
Interesting that Laos and India both called this flower ‘Champa’. I went through pictures of my Laos Trip, and realized that I took quite a bit of pictures of Dok Champa and Champa tree, here are some.
