Why Sunfire Coreopsis Seeds belong in Your Garden
If you need a reliable “workhorse” for your perennial border, Sunfire is a top contender. It is tough enough to withstand Zone 3 winters and unappealing to deer, making it perfect for rural or suburban gardens alike. Its exceptionally long bloom window—spanning from early summer until the first hard frost—ensures your garden remains a vibrant sanctuary for you and local pollinators for months on end.
