The garden centre is inviting teachers to register online for their free learning resource which illustrates how sunflowers can be used to link a multitude of subjects, from science and nature to famous artworks, geography, culture and foods.
The learning resource also includes the template for the seed packet design which will be at the heart of the competition. Entries will be displayed in the Hayes Garden World Ambleside store, where the public will be asked to vote for their favourites during the summer.
The competition runs untii 17th July 2015. The three winning entries will be announced during the week of 7th September, the first week of the Autumn school term, with the winning schools being awarded £1000, £750 or £500 as first, second or third prize winners.
Lyndan Orvis, digital media manager at Hayes Garden World, said: "Growing sunflowers from seed has always been one of our most popular Budding Young Gardeners activities and so this national schools initiative is a natural development for us and one that we are delighted to support in this, the Year of the Sunflower".
