Common name: Flaming Glorybower, Pagoda Flower, Bleeding Heart Vine.
Native to Western Africa. Flaming glorybower is a woody or semi-woody evergreen vine or running shrub that climbs by twining. The leaves are oval and arranged in opposite pairs. This particular vine had extended to the neighbouring house too. And it seems they were not unhappy about it and infact had allowed it to trail over their balcony.
Botanical name: Clerodendrum splendens Family: Verbenaceae (verbena family)
