影樹（鳳凰木）花期結束 《維園火焰 》，到雙翼豆吐艷。將兩者相提，因她們同目同科（豆），傘形樹冠，二回偶數羽狀複葉都相似。且兩者英文俗名均取材火焰，一紅一黃。
yellow flame trees just started blossoming. i have spotted quite many of them these few days on hong kong island. at victoria park, in central. if you see some handsome-built trees around the city, rich in bipinnate leaves and attractive yellow flowers in large compound racemes, they are the one.
yellow flame trees and the flame of forest look alike. the latter just finished their fire-hot flowering season 《 red hot victoria park》 . they belong to the same order and family, thus the similarities in the apprearances. both have feathery leaflets. yellow flame tree’s leaflets are however relatively bigger and with smaller number in each leaf.
it has another common name – yellow poinciana. poinciana refers to fruit with wings. yellow flame trees produce copper-coloured pods and ripen in black. the pods are a bit flat in the middle with the edges look like wings.
one note, yellow flame tree was popular as a cultivated species but not any more. therefore, most of the trees we now appreciate their glory blooms are tall and big, meaning they are an aging species in this city.
