How to Grow Rainbow Mixed Color Lupine Seeds:
Start by prepping seeds for better sprouting because the coat is hard. Lightly nick or rub each seed with sandpaper, then soak in room-temperature water for 8–12 hours and sow right after. Plant outdoors in early spring after frost (or late fall in cool areas), or start indoors 6–8 weeks before the last frost using deep pots to protect the taproot. Sow 0.5–1 cm (¼–½ in) deep, keep soil lightly moist but not wet, and expect germination in about 14–28 days in cool conditions. Choose full sun in cool climates; in hot climates give morning sun and light afternoon shade. Use loose, well-draining, slightly acidic to neutral soil—avoid heavy clay and soggy spots.

How to Care for Rainbow Mixed Color Lupines:
Water gently while seedlings are small, letting the surface dry a bit between waterings. Once established, water deeply 1–2 times per week during dry spells and avoid waterlogging. Feed sparingly with a low-nitrogen bloom fertilizer once in early spring; too much nitrogen makes leaves grow at the expense of flowers. Stake tall spikes if your area is windy, and deadhead spent flower stalks to encourage a second flush; leave a few pods only if you want self-seeding. Keep plants spaced for airflow and watch for aphids or slugs—treat early with simple methods like water spray, neem, or barriers. After flowering or first frost in perennial areas, cut stems down and mulch lightly to help the plant return stronger next season.
