Solanum macranthum: Flowers with different colours?

[Navin]

I was walking around in school when I came across this plant which I identified as Solanum macranthum or also known as Giant Star Potato Tree. I think it belongs to the same family as the eggplant or aubergine.

I found it had interestingly shaped leaves but the unique thing was that it had clusters of flowers with different colours on them. Some were dark purple some were white and some were in between.

Could anyone explain to me how this is possible.

I don't know the plant you discussed, but I do know that lots of flowers change color when they stop producing pollen--families as diverse as Cactaceae, Verbenaceae, Polygalaceae, etc.

[MrMistery]

your plant belongs to the family Solanacee
I have flowers in my front yard that show the exact same trait(flowers of different colors on the same plant)
i atributes this to some unequal distribution of cellular components in the initial division that gave rise to the new flower. But i was probably wrong.
