Dye flowers

The highly colourful flowers have been developed by a Dutch businessman who dyes each bloom in the colours of the rainbow.
The dyes are produced from natural plant extracts and are absorbed by the flowers as they grow.The 'Happy Flowers' were designed by Peter Van de Werken, who owns a flower company close to Den Bosch in southern Holland.
The firm sells only multi-coloured roses and chrysanthemums but is also looking to do pot plants.
Mr Van de Werken, 36, said: 'We used to only sell single colour flowers but the market for them took a dip.
'Myself and my colleagues started looking for something a bit different and came up with the idea of having different-coloured flowers. 'First of all we tried spraying the flowers but that did not work. Then we tried the dye. It took us about six months to get it right and we still make mistakes.'
