      Hi iluvgok,
      Thanks for all your questions! They are really interesting.
      Flower colour in plants is something that is controlled by DNA so yes we can change it and change the colour of the flowers. There are two ways we can do it:
      We can breed two different flowers together to give us new flower colours or we can use biotechnology to put new genes into the plants genome for new flower colours.
