An excellent shade tree, the Angsana can grow up to 40m tall. It was planted extensively in the 1960s and 1970s as part of Singapore's efforts to green up the country. It has yellow flowers that grow in large bunches. Its fruits are flattened disc-shaped pods with papery wings. One of the largest roadside trees in Singapore is an Angsana Heritage Tree with a girth of 7.7m. It can be seen along the road verge of Upper Serangoon Road, between Woodleigh Park and Woodleigh Close and is about 60 years old.
