Planting & Care

Sow Hartwegii Mix Lupine seeds indoors 6-8 weeks before the last frost or directly outdoors after the danger of frost has passed. Scarify seeds by nicking the hard coat or soaking in warm water for 24 hours to improve germination. Plant seeds 1/4 inch deep and keep the soil consistently moist until germination, which typically occurs in 14-21 days. Once seedlings have two sets of true leaves, thin or transplant to 12-18 inches apart.

Lupines prefer cool weather and may struggle in extreme heat. Water regularly during dry spells, but avoid overhead watering to prevent disease. Mulch around plants to retain moisture and suppress weeds. Deadhead spent flowers to encourage continued blooming, but allow some flowers to go to seed if you want them to self-sow for next year.
