In honour of this landmark anniversary, ‘Growing for Gold' is the 2014 theme of RHS Britain in Bloom. Many of the 300,000 volunteers will be sowing a variety of pollinator-friendly sunflowers including the Giant Single, the Moonwalker, Taiyo and Vanilla Ice, all provided for free by the RHS.
RHS community horticulture manager Stephanie Eynon said: "What better way to celebrate this huge anniversary for Britain than a mass planting of beautiful golden sunflowers. These gorgeous and uplifting plants have been known to grow an astonishing 20 feet high, which reflects the sort of spirit and drive we associate with RHS Britain in Bloom volunteers.
"We're providing the seeds as a big ‘thank you' to all the industrious and passionate people who work year-round to make the UK clean, green and beautiful. It is also a chance to do something big for the environment. As well as being symbolic of RHS Britain in Bloom's 50th year, these glorious fields of gold will provide vital food for pollinators this summer."
