Now there is no need to replace your sunflower plants over and over to enjoy their sunny disposition all summer long because Sunfinity boasts continuous growth and blooming all season long! Sunfinity keeps on growing long after traditional single-stem sunflowers have bloomed and died. Throughout the season, you can cut Sunfinity sunflower stems and bring them into your home to enjoy. They leave no messy pollen on your tables and will keep for 7 days or more in tap water.
