Description

(Tropaeolum nanum). Compact plants produce loads of citrus-hued orange blooms with a brilliant burst of flavor. The Whirlybird nasturtium is both ornamental and edible; its flowers and leaves offer a peppery flavor for salads and garnishes.

Growing Tips: The Whirlybird Tangerine nasturtium thrives in well-draining soil and full sun but can tolerate light shade. They are fairly drought-tolerant and grow well in a variety of soils, including low-fertility soil, as long as it is well-draining. Avoid fertilizing or planting in overly rich soil, as this will encourage more leaves at the expense of flowers.

When to Grow

Start seeds indoors 4 weeks before your last frost date or direct sow outdoors after the last frost has passed. Check your local area's frost dates and plan accordingly. The ideal germination temperature is 55-65 F, so ensure soil temperatures fall within this range for successful germination. In warmer climates, nasturtiums can also be sown in the fall for winter blooms. If you're unsure of your last frost date, consult our blog post 'Our Experts Answer Questions, Share Resources'.

How to Sow and Plant

Soak nasturtium seeds overnight in warm water to soften the seed coat and improve germination rates. Plant seeds 1/2-1 inch deep in well-draining soil. Space plants 8-12 inches apart to give them enough room for growth and airflow. Nasturtiums grow best in full sun but can tolerate some light shade. While they prefer dry, low-fertility soil, ensure it is well-draining to prevent root rot. Seeds typically germinate within 7-14 days when sown at the proper soil temperature.

How to Grow

Water sparingly once plants are established, as nasturtiums are fairly drought-tolerant. Avoid overwatering to prevent root rot and excessive foliage growth. Deadhead flowers to encourage continuous blooming. These plants are also great companion plants, as they attract pollinators such as bees and butterflies while helping repel some pests. If aphids appear, simply spray plants with water or apply insecticidal soap to manage them.

How to Save Seeds

  • 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.
