Untouched Original colour/color Photograph by J. McCombie. Sunflowers are the kings of the natural sunny summer garden, attracting butterflies and birds. They’re wonderfully easy to grow—just direct-sow the large seeds after all danger of frost. Not picky about soil type, they need direct sun. Thin the plants to 2 to 4 feet apart so that they can show off their foliage a bit as they grow. The Color Fashion Mix is a beautiful blend of yellow, red and brown single flowered sunflowers which provide excellent cutting material and a tall border. They have medium sized 4 inch blooms on 6 foot stalks.
