With Dahlias being Octoploids growing them from seed is always somewhat of a mystery. Every seed will have its own unique flowers that do not already exist. Growing: starting the seed indoors (recommended) up to 4-6 weeks before your regions last frost date. Cover seed with growing medium and keep moist until germination approximately 3-5 days under optimal conditions. Requires soil temperatures of 65-70. Do not start too early as root bound plants will have trouble during transition. Root disturbance can impact plant health. Harden off plants before transplanting outdoors. Direct seeding can be done once all danger of frost has passed and soil temps have warmed to at least 65. If this method is chosen you may get later blooms than if started indoors/transplanted. From seed to maturity is around 90 days. Plants will produce tubers which can be dug and saved to plant out again the following spring. In fall once plants have started to die back but before any major frost cut plants stems back to about 2" above soil line. Gently dig up tubers and remove as much soil as possible. Before final winter storage let them dry out up to 4 days in a warm location without direct sunlight and sufficient airflow. There are a few different storage methods.
