Racemes extending from the branch end or leaf axils, flowers colored bright red to orange red with yellow and white markings, flower in a diameter of 7-10 cm. Pods flat, long and slightly curvy, 30-60 cm long and 3.5-5 cm wide. Flowering from June to September, and fruiting from August to October.

適合全日照且溫暖環境，植株耐乾燥，在乾溼季分明的環境下開花更繁盛。一般不進行縮短修剪，僅修除樹冠內的不良枝。繁殖採用播種法。

It suitably grows in full sun and warm environments; it’s resistant to dryness and blooms profusely in distinct dry and wet seasons. Generally, dwarf pruning is generally not necessary, only the unwanted branches within the crown need removed. Propagated by seeds.

枝葉平展，適合作為庭園樹以提供樹蔭。栽培地點較須開闊，以免與其它樹有樹冠重疊現象。根系容易隆起成板根，須預留較大樹穴並勿用水泥等硬鋪面覆蓋樹基部。

Featuring with flat and spreading crown, the plant is a great shade tree. The plantations must be open and broad enough to avoid overlapping with other trees. The roots easily rise and form buttress roots, therefore a larger tree well should be reserved in advance and never use hard pavement material such as cement to cover the tree base.
