Planning to grow sunflowers this year? Wait until after the last frost (usually around April or May), then find a sunny spot with rich, well-draining soil to plant the sunflower seeds in. Monitor them on a daily basis over a cup of tea in your Sunflower 1/2 Pint Mug. Or, if planning a sunflower competition this year, this hand-decorated floral mug will make the perfect prize for whoever manages to grow the tallest sunflower.
