This flower is one of the loveliest flowers I have ever seen in the parks of Singapore. I first saw these flowers at Labrador Park along the sea front. I remember that they were high up on the branches and were difficult to photograph.
Recently, I saw a small tree in West Coast Park with a number of flowers that were within easy reach.
There were also many flowers on the grass as they bloom in the night and fall to the ground in the morning. I was lucky to find that most of them were still complete and not scattered about as would have been the case if the tree were taller like those at Labrador Park.
