Growing Information
Planting:
Start inside in peat pots 6-8 weeks before last frost. Chip seeds or soak in warm water for 24 hours before sowing 1⁄8 inches deep. Provide cool temperatures (13-18 degrees C) and seed should germinate in 1-2 weeks. May also be direct seeded in very early spring or late fall. Seed rate for direct seeding of Lupins: 1 lb/1000 sq.ft. or 5 g/sq.meter. Frost will help break the hard seed coat. Transplant outside after last frost into full sun or light shade 12-18" apart.
Growing:
Plant in groups for best show. Water and deadhead regularly. Feed with a low-nitrogen, high-phosphorus fertilizer.
