Few flowers capture the summer spirit like sunflowers. Their golden faces, tall stature, and pollinator-friendly nature make them one of the most iconic and beloved flowers to grow. But not all sunflowers behave the same — some produce one large bloom, others produce dozens, and newer varieties like Sunfinity sunflowers produce hundreds of continuous flowers all season long.

This comprehensive guide will help gardeners, cut-flower growers, sunflower lovers, and beginners understand which sunflower varieties to plant, how to grow them from seed, and the best place to buy sunflower seeds for success.
