Gardeners are being encouraged to swap the traditional white rose of Yorkshire for yellow as the Tour de France comes to the Bradford district next July The Royal Horticultural Society (RHS), working in conjunction with Welcome to Yorkshire, has produced a factsheet to help people turn Yorkshire yellow next summer.

It contains information about more than 80 different kinds of plants with yellow flowers or yellow foliage – including four varieties of yellow rose – as well as tips on when to plant them and how to maintain them ahead of the weekend of July 5 and 6. Gary Verity, chief executive of Welcome to Yorkshire, said: “The Grand Départ provides Yorkshire with a unique opportunity to showcase what the county has to offer.

“We understand the economic advantages of attractive places and with the help of the RHS we want to enhance the county, creating show stopping floral displays that will wow the crowds next summer.”
