My name has green, but my flower has violet

Well I will tell you the title of my post will be quite confusing and believe me I have no idea why I made it that way, hahah. But my intention is that the name of this particular flower is literally different from the color of its flower, will most plant is like that, isn't it? But anyway I will stick to that title, just because I like to make you confused also.

For today's post, I have a flower of a plant that is called green chireta or Andrographis paniculata and they are natives to India and Srilanka, but I found it here in Bali in an unattended bushy area.

Despite having to bear green on its name, they have a white color flower with a little bit of violet on its petals. It is said that they can be used to cure bacterial infections, but I have never tried it before.
