Planting & Care

To start Russell Blue Lupine from seed, scarify the seeds by nicking the seed coat or soaking in warm water for 24 hours. For best results, cold stratify seeds by placing them in a moist medium in the refrigerator for 4–6 weeks before sowing. Sow seeds indoors 6–8 weeks before the last frost or directly outdoors in early spring. Press seeds into the soil surface and cover lightly with 1/8 inch of soil. Keep consistently moist at 65–70°F (18–21°C). Germination typically occurs in 14–30 days.

Transplant seedlings outdoors after the danger of frost has passed, spacing them 12–18 inches apart. Choose a location with full sun to partial shade and well-drained soil. Water regularly during establishment. Mulch around plants to retain moisture and suppress weeds. Deadhead spent flowers to encourage reblooming and prevent self-seeding if desired. In hot climates, provide afternoon shade. Lupines benefit from a layer of mulch in winter to protect crowns.
