Growing Instructions

Direct sow outdoors in early spring or fall, or start indoors 6–8 weeks before last frost. Lightly cover seeds and keep soil evenly moist during germination. Seeds benefit from soaking in warm water for 12–24 hours or gently nicking the seed coat to improve sprouting. Transplant carefully, as lupines develop deep taproots and dislike disturbance. Prefers well-drained, slightly acidic soil and moderate watering. Deadhead spent blooms for a possible lighter second flush or leave pods to self-seed naturally.
