Zinnia Seeds,
Polar Bear

Plant Polar Bear zinnia seeds after the last frost in spring, when soil temperatures have warmed. In most USDA zones, this typically means planting in late spring. In warmer climates, succession planting every few weeks can extend blooming well into autumn. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

Directly sow the seeds in a sunny, well-draining location, about 1/4 inch deep and spaced 9-12 inches apart. This will provide good airflow and reduce the risk of mildew. For earlier blooms, you can start seeds indoors about 4 weeks before the last frost and transplant them once the soil has warmed up. Use biodegradable pots or other means to minimize root disturbance when transplanting​.

Polar Bear zinnia requires 6-8 hours of full sun daily and consistent watering. You can apply a balanced fertilizer once a month during the growing season. Cut frequently or remove spent flowers for the highest production.

• Allow the flowerhead containing the seeds to mature and dry on the plant.
• Clip off the flowerhead and place it in a paper bag or other container.
• Working over the top of another clean, opened container, rub the flowerheads between the palms to break them apart.
• The seeds can be separated from the chaff by first screening and then winnowing.
• Store in a cool, dry, dark place over winter.
