Making a Black rose?

Question

In science last year we conducted a small experiment (a rather boring one might I add) were we put celery in dyed water and the celery turned red. Is there anyway to perform such an experiment, only making a rose black because I know there isn't an actual "Black rose" in nature, only the baccara which is just a dark red. Is there anyway at all to make a black rose?

Answer 1

well, you can start from scratch yourself and put a rose in black die, just like you did with the celery. If this is a gift though,you'll have to make sure it doest die ( it probably takes time for this process). Maybe put it in a glass with it roots still? If your just experimenting, i encourage you to try it out though. And again, if it is a gift, you may want to try it out on a practise one, also to see how long it lasts.

If your just looking for one though, and your open to buying one, go to a local flourists' ( a good one) and ask what they have to say about your predicament. They might just make a custom order!

The search for black flowers is actually a search for ever and ever deeper shades of blue and purple. "True black", i.e. the absorption of all light, is rare in nature, except perhaps in the case of a black hole.    

There are a number of flowers commonly on sale at the florist which are coloured by dyed water, most classic of which are carnations and lilies. However, the colour does not penetrate all the cells on the petals evenly and the water conducting tissues, the xylem, are darker in colour than the rest of the petal. I cannot see why this should not work with roses.

However, as black pigment is not a single primary colour but is a mixture of different light absorbing pigments ensuring that a minimal amount of light is reflected back, I am not sure how well this will work. These different pigments may move through the stems at different rates and so you may get some interesting results.
