Clitheroe is being turned Purple4Polio by the Rotary Clubs of Clitheroe and Ribblesdale together with the pupils of Ribblesdale High School.
Ruby giant crocus corms have been planted in open green spaces in Clitheroe to raise awareness of Rotary International’s campaign to fight polio.
It is hoped the purple crocuses will add a splash of colour and vibrancy to the town.
Rotary and its members have been committed to fighting to eradicate polio across the world for more than 30 years.
The amount of polio-endemic countries has dropped from 125 to just two, with more than 2.5 billion children receiving vaccinations thanks to the help of Rotary.
