Moonlight Nasturtium spills over the garden with a cool, luminous presence—delicate blossoms in pale, creamy tones that feel like moonlight caught on the vine. The tender leaves and succulent, peppery seed pods bring a crisp, juicy bite with a gentle heat, ideal for bright garnishes and quick pickling. Grow it for a long season of trailing color and a harvest that’s as lively in flavor as it is in form.

Frequently Asked Questions

What’s the most common disease pest issue for Tropaeolum majus (moonlight nasturtium), and how can I prevent it?
Nasturtiums are frequently affected by aphids and sometimes bacterial leaf spot under warm, humid conditions. Spray plants with a strong jet of water to knock off aphids, then use insecticidal soap if they persist, and remove badly spotted leaves to keep airflow high. Water at the soil line (not on foliage) to reduce disease spread, and avoid crowding so leaves dry quickly after rain or irrigation.
How can I tell when moonlight nasturtium (Tropaeolum majus) is ready to harvest?
Harvest is typically ready around 50 days from sowing when plants have abundant open flowers and the foliage is lush and healthy. For flowers, pick blooms as soon as they open fully—regular harvesting encourages more flowering. If you’re harvesting seeds, wait until seed pods turn greenish-brown and rattle slightly when dry, then collect them before they fully scatter.

Sowing Tips

Soil Temperature

Direct sow or transplant when soil at planting depth holds 55°F for reliable germination and early growth.

Expert Note

Sow directly after the last frost (or in warm pockets earlier), since nasturtium roots dislike transplanting and plants flower best in full sun.
