Grow your own dahlias with seeds harvested from The Flowering Farmhouse! Unlike dahlia tubers, dahlia seeds will produce a new and unique variety. Dahlia seeds will produce tubers in one growing season. Each packet contains approximately 25 seeds harvested in 2022. Dahlia seeds have a lower germination success rate than most seeds. You can expect anywhere from a 20-80% germination rate. The range is so wide as larger dahlias and closed center dahlias tend to have lower success rates. I’ve done my best to hand select ripe and full dahlia seeds. There is no guarantee on size, shape, or color on dahlias grown from seed. Each one will be unique and beautiful. Most dahlias grown from seed will produce open centered dahlias. How to Grow: Sow dahlia seeds indoors 4-6 weeks before your last frost. Transplant out after danger of frost. Dahlias need at least 120 days of growing to produce viable tubers.
