Pupils from St Hilda’s Primary School in Whitby gave up some of their lesson time to help plant 5,000 crocus corms around the play area in Pannett Park.
They were assisted by some of the Friends of Pannett Park group and Scarborough Borough Council gardening staff.
The project, Purple for Polio, involves Rotary International in Great Britain and Ireland in partnership with the Royal Horticultural Society.
Having been behind the massive reduction of polio-endemic countries over the past 30 years, The Rotary Foundation designed a campaign as, hopefully, a final push to eradicate polio completely.
The RHS joined the campaign as a means of brightening up public spaces with the crocus Ruby Giant, chosen to represent the purple dye used to mark the finger of children who have been immunised.
The planting also fits with the current RHS campaign Greening Grey Britain, with the two organisations aiming to get six million corms planted, adding a bright splash of colour to many areas in the spring for years to come.
