Black Lotus? Possible dying techniques?

Question

A dear friend of mine (or rather, a friend who has recently crossed the line to lover, but we are NOT a couple) has eyes for only one blossom. And that would be the serene beauty of the lotus.
However, my lover and I are two birds of the same, off-beat feather. We have a taste for the Dark and Gothic. As such, he has always wanted to see a black lotus.
I decided that I want to grow him a lotus now. But I need to ask, how on earth can I properly dye one black?

Answer 1

Maybe this will help

People dye flowers all the time, shouldn't be too hard to make one black.
