Description

(Tropaeolum majus). Leaves shaped like English ivy and flame-shaped flower petals make Phoenix a unique twist on our favorite edible ornamental. The colors are a mix of warm shades, from scarlet to bronze, mahogany, and apricot. These plants are semi-trailing; they will cascade from hanging baskets or sit compactly in beds. The unusual ivy leaf and flower shape can be traced back to seed catalog offerings of the early 1900s, often listed simply as ivy-leaved nasturtium; this is a new spin on an antique novelty.

Growing Tips: The Phoenix nasturtium is an heirloom variety that prefers full sun but also tolerates partial shade in hot climates. It thrives in poor to moderately fertile, well-draining soil, with minimal care and no fertilization needed.

When to Grow

Sow seeds outdoors in the spring after the last frost when soil temperatures reach at least 55 F. For earlier flowering, seeds can be started indoors 4 weeks before the last frost date, then transplanted carefully after hardening off. Checking your region's frost dates will help determine the best planting time. If you're unsure of your last frost date, consult our blog post 'Our Experts Answer Questions, Share Resources'.

How to Sow and Plant

Nasturtiums are best direct sown in the garden, planting seeds 1/2-1 inch deep and spacing them 8–12 inches apart. To speed up germination, soak seeds in warm water overnight before planting. Seeds germinate best at 55-65 F. For indoor starts, use small pots or biodegradable containers to minimize root disturbance when transplanting into a sunny, well-draining garden spot.

How to Grow

Once established, Phoenix nasturtiums require minimal watering and care, as they are drought-tolerant and thrive in lean soil. Water sparingly, allowing the soil to dry slightly between waterings, and avoid overwatering, which can lead to root rot or excess foliage growth. Deadheading spent flowers will encourage continuous blooming, and pests like aphids can be managed with water sprays or neem oil.

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.
