flower science experiment

I did a science experiment to see if white flowers would change colour if food colouring or dye was put in their water. 

I used 6 different white flowers and used green, blue, red, pink, yellow and black for the colours.

I thought the white flowers would change colour because they drink from their stems.

The first flower to change colour was the rose. It started to go green after about 17 minutes.  I think this is because the stem is softer than the other flowers or it may be a better drinker than
the other flowers.

The white alyssum (tiny flowers) turned blue but took a lot longer than the other flowers.  By the next day, the leaves had changed from green to blue too!

The white camellia didn’t change colour at all.

The flowers started to change colour from the outside of the petals and slowly went into the centre.  Some of the pollen in the middle also changed colours. At the end, some of the petals fell off.

Some of the photos below show that they changed colour.

At the beginning this is what the flowers looked like:

At the end of the experiment they looked like this:
