It will grow best in a rather moist garden location. Fast growing and flowering; it can flower in the second year when grown from seeds.
Germination: best after providing 3-4 weeks of cold/moist stratification, then treated as a warm germinator. It can be started early at room temperature, or time the cold stratification accordingly and sow outdoors in the spring when weather allows.
