Planting & Care

Sow lupine seeds indoors 6–8 weeks before the last frost or directly outdoors in early spring after scarifying the seed coat. For best results, cold stratify seeds for 1–2 weeks before sowing. Press seeds into the soil surface and cover lightly, as light aids germination. Keep the soil consistently moist at around 65–70°F. Germination can be slow and uneven, taking 14–30 days.

Once seedlings have several true leaves, transplant them to the garden after hardening off. Space plants 12–18 inches apart in a sunny location with well-drained soil. Water regularly during establishment, then reduce frequency as plants mature. Mulch to retain moisture and suppress weeds. Deadhead spent blooms to encourage reblooming and prevent self-seeding if desired.
