Variety History

Nasturtiums are native to the Andes and were brought to Europe by Spanish conquistadors in the 16th century. The name comes from the Latin "nasus tortus" (twisted nose) referring to their peppery bite. They became enormously popular in Victorian gardens.

Regional Context

Nasturtiums are one of the most rewarding flowers for PNW gardens. They bloom prolifically from June through first frost with essentially no care. Plant them along the edges of vegetable beds — they cascade beautifully and protect your crops. Jewel Mix includes red, orange, yellow, and peach blooms. The peppery flowers make any salad look like a restaurant dish. They self-sow enthusiastically and will return year after year.

Growing Technique

Direct sow after last frost (mid-May). Push large seeds 1" deep, 4 seeds per sq ft. Nasturtiums thrive on neglect — rich soil produces all leaves and few flowers; lean soil produces abundant blooms. Full sun to partial shade. Do not fertilize. They are trailing or mounding plants — Jewel Mix is a compact bush type. Water sparingly once established. Nasturtiums are the ultimate companion plant: they act as a trap crop for aphids (aphids prefer them over vegetables), attract pollinators, and repel some pests. Every part of the plant is edible — leaves, flowers, and seed pods all have a peppery, watercress-like flavor.

Watch For

  • Too much nitrogen produces lush leaves and zero flowers — this is the #1 complaint. Plant in lean soil and NEVER fertilize. Aphids love nasturtiums (this is a feature as a trap crop, but can look alarming — just let them be or spray with water). Slugs at seedling stage. Powdery mildew in late season — cosmetic only.
