I love growing mammoth sunflowers! Plus my bees love it too!
Put 2 cups of sunflower petals in a pot of water to cover and bring to a boil. Turn off heat and let petals seep for one hour. Strain petals and put 3 cups of the water in a large pot. Add a package of pectin and 1 teaspoon of lemon juice. Bring to a boil and add 3 1/2 cups of sugar. Bring mixture back to a boil and boil for two minutes. Turn of heat! Pour jelly into prepared jars. Enjoy!!!
