I remember seeing these shrubs as a child always from a distance in a moving car and have wondered about these lovely flowers. I don't see them so often nowadays except on this particular occasion when I spotted a row of these shrubs in bloom below a block of HDB flats. Curious I went closer to examine them and found to my pleasant surprise that what I had always thought were petals of flowers were actually bracts and the flowers are small but delightful in shape and colour.
