Santan flowers are beautiful and vivid. Depending on cultivars, the colors may be white, red, orange, pink or yellow.
Children collect the little santan flowers and create necklaces with them.
Adults, however, obtain and use them for treatment of dysentery and other diseases.
I remember when I was little kid, together with my brothers and my friends,
We pick-up those little flowers and start plucking those thin needle-like structure from its stem
and start drinking its sweet nectar liquid.
