Description

(Tropaeolum majus). Shocking color that is quite unique to nasturtiums! Behold a bewitching color transformation as these bold burgundy-purple blooms evolve into a vintage dusty lavender-rose hue throughout the season. This semi-trailing type makes compact vines reaching 18-24 inches long. Tumbling vines of rose and wine-colored blooms make Purple Emperor the most incredible edible ornamental. Blooms and leaves are peppery and add kick to recipes while the green seed pods can be pickled into imitation capers.

Growing Tips, Tricks and FAQs

Growing Tips

Purple Emperor nasturtium is a perfect choice for flower beds, containers, and hanging baskets, combining beauty with functionality. It thrives in full sun but will tolerate partial shade in hot climates. It prefers lean, well-draining soil, as richer soils encourage excessive foliage growth rather than flowers.

When to Grow

Direct sow seeds outdoors in spring after the last frost date, when soil temperatures are consistently above 55 F. For a head start, start seeds indoors 4 weeks before the last frost date, and transplant them outdoors after hardening off. If you’re unsure of your last frost date, consult our blog post ‘Our Experts Answer Questions, Share Resources.’

How to Sow and Plant

Sow seeds 1/2-1 inch deep and space them 8–12 inches apart directly in the garden. To speed up germination, soak seeds overnight before planting. Germination takes 7–14 days. If starting indoors, use biodegradable pots to prevent root disturbance when transplanting. Choose a sunny location with well-draining soil for planting outdoors, as nasturtiums prefer poor to moderately fertile soil to encourage blooms.

How to Grow

Water sparingly, allowing the soil to dry slightly between watering, as overwatering can cause root rot or excessive foliage. Deadhead spent flowers for continuous blooming throughout the growing season. Avoid fertilizing, as nutrient-rich soil can reduce flower production. While nasturtiums are generally pest-resistant, they can attract aphids. If needed, treat infestations with a strong spray of water or neem oil.

How to Save

  • Nasturtiums will often reseed, but to save seeds, allow them to mature and fall to the ground.
  • Collect them and store them in a cool, dark, dry place over the winter.
