Nasturtium Seeds,
Orchid Flame

Plant Orchid Flame nasturtiums outdoors only after the last frost date in spring, as the plants are highly frost-sensitive. Direct sowing is recommended, but seeds can also be started indoors 4 weeks before the last frost using biodegradable pots to minimize root disturbance. In warmer climates (zones 9-11), this variety can be grown year-round or during the cooler months as a winter annual. For help determining your frost dates, refer to our blog post, 'Our Experts Answer Questions, Share Resources'.

Nasturtiums are best direct-sown into the garden. Soak seeds in warm water overnight before planting to improve germination. Sow seeds 1/2-1 inch deep and space them 8-12 inches apart. Germination typically takes 7-14 days. If starting seeds indoors, use biodegradable pots to prevent root damage when transplanting. Thin seedlings as needed to allow proper spacing and airflow once they emerge.

Orchid Flame nasturtiums perform best in full sun, needing 6-8 hours of sunlight daily for best flower production. Water deeply once a week, increasing frequency during hot or dry spells, but avoid overwatering, as the plant prefers well-draining soil. Fertilizing is unnecessary, as nutrient-rich soil may lead to excessive leaf growth at the expense of flowers. Deadhead spent blooms regularly to encourage continuous flowering throughout the growing season.

• Nasturtiums will often reseed, but to save seeds, allow the flowers to mature and let the petals fall to the ground.
• Collect the seeds from the plant before they fall.
• When the seeds are dry, label and store them in a cool, dark, dry place over the winter.
