Russell Hybrid Mix Lupins
Lupinus polyphyllus. This popular and colourful perennial blooms throughout June and July. Tall graceful spikes in shades of red, yellow, rose, and blue. Lupins grow nicely in slightly acidic soil. Height 2-3 feet. Start seed indoors 6-8 weeks before planting out. Approximately 65 seeds/pkg.
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.
Plant in groups for best show. Water and deadhead regularly. Feed with a low-nitrogen, high-phosphorus fertilizer. Lupins are short-lived (3-4 years), but they self-seed reliably although the new plants often revert to blue.
